Jupiter because of its strong gravitational force
Explanation:
Jupiter planet has the most important role in changing the direction of a comet's path. The correct option is C.
What are gravity and gravitational force?Gravity is a fundamental force in the universe that causes objects with mass or energy to attract one another. It is a force of attraction between any two objects in the universe that have mass. The force of gravity is directly proportional to the masses of the objects and inversely proportional to the distance between them.
Mathematically,
F=G×m1×m2/r²
The gravitational force is the force of attraction between two objects due to their masses. It is the force that causes objects to be drawn toward one another.
The strength of the gravitational force between two objects is determined by the mass of each object and the distance between them. The larger the mass of an object, the greater its gravitational force, and the closer two objects are, the greater their gravitational force.
Gravitational force is responsible for keeping the planets in orbit around the sun, for the tides on Earth, and for many other natural phenomena. The gravitational force is one of the four fundamental forces of nature, along with the strong nuclear force, the weak nuclear force, and the electromagnetic force.
Here in the question
Jupiter's strong gravitational force can significantly influence the trajectory of a comet, causing it to change direction or even collide with the planet. This is due to Jupiter's massive size, which creates a powerful gravitational pull that can affect objects within its vicinity. In fact, Jupiter is often referred to as the "vacuum cleaner of the solar system" because it has such a strong gravitational pull that it can attract and capture comets and asteroids.
Hence C. Jupiter because of its strong gravitational force, plays a most important role in changing the direction of a comet's path.

An 8.8-magnitude earthquake in Chile in 2010 killed more than 700 people. On January 12, 2010, a less powerful earthquake, measuring 7.0, killed more than 200,000 in Haiti. Why do you think this happened?
Answer:
The main reason for this is the engineering and technology driven building construction in Chile than in Haiti
Explanation:
The main reason for this is the engineering and technology driven building construction in Chile than in Haiti. Most of the buildings in Haiti do not fit in the building byelaws norms as most of them were constructed in a short period of time with less engineering and at cheaper rate. While building in Chile were built adhering to the building codes and byelaws.
The base of the building is Chile were separated from each other using the “base isolation” technology and the were also more flexible as compared to the buildings in Haiti.
The skyscrapers in Chile were constructed in a way that they can float on the arrangements of ball bearings and padded cylinders

The smaller the mass of an object, the _____ its inertia
Answer:
larger
Explanation:
just trust me
The smaller the mass of an object, the smaller its inertia, because the inertia of any object is directly proportional to the mass of the object
What is inertia?The ability of an object to resist changes in motion is known as inertia. The amount of inertia is directly related to an object's mass; in fact, as we frequently observe, the heavier an object is, the harder it is to change its direction of motion.
A straightforward illustration: While it is relatively simple to stop a tennis ball that has been thrown in our direction, we are aware that it is more difficult to stop a large truck that is moving in the same direction at the same speed. This is because the truck has a much higher mass than the tennis ball and a higher moment of inertia. As a result, inertia rises as mass does.
Since the inertia of any object is directly proportional to its mass, the smaller its mass, the less inertia it will have.

The conversion of sugar to energy in the presence of oxygen is
A.
respiration
B.
protein synthesis
C.
binary fission
D.
photosynthesis
Answer:
A. respiration.
Explanation:
Cellular respiration can be defined as a series of metabolic reactions that typically occur in cells so as to produce energy in the form of adenosine triphosphate (ATP). During cellular respiration, high energy intermediates are created that can then be oxidized to make adenosine triphosphate (ATP). Therefore, the intermediary products are produced at the glycolysis and citric acid cycle stage.
Additionally, mitochondria provides all the energy required in the cell by transforming energy forms through series of chemical reactions; breaking down of glucose into Adenosine Triphosphate (ATP) used for providing energy for cellular activities in the body of living organisms.
Basically, oxygen goes into the body of a living organism such as plants, humans and animals when they breathe while glucose is absorbed by the body when they eat.
Hence, the conversion of sugar to energy in the presence of oxygen is respiration.

Consider again the civilization described in the previous question. (They live on a planet orbiting 10 AU from a close binary star system that consists of a 15 MSun red giant star and a 10 MSun black hole surrounded by an accretion disk.) Through a bizarre (and scientifically unexplainable) fluctuation in the space-time continuum, a copy of a book from that civilization arrives on your desk; it is entitled Iguoonos: How We Evolved. In the first chapter, you learn that these beings evolved from organisms that lived 5 billion years ago. Which of the following statements should you expect to find as you continue to read this book?
A. Their immediate ancestors were chimpanzees.
B. As a result of traumatic experiences to their evolutionary ancestors, they dislike television.
C. They evolved on a different planet in a different star system, and moved to their current location.
D. They evolved from primitive wormlike creatures that had 13 legs, 4 eyes, and bald heads, thus explaining why such critters are now considered a spectacular delicacy.
E. They believe that the presence of two stars in their system was critical to their evolution.
A car travels in 300 km in 3 hours. What can be determined?
Answer: If a car travels 300 km in 3 hours, then it’s speed will will be 100 km/hr. But in practical it depends upon type of car, condition of car, car's maximum speed and also the path in which car is travelling.. Because car can't travel in constant speed of 100 km/hr. So, if car have 120 km/hr as maximum speed than it's minimum speed will be 85–95 km/hr. And so the car travel 300 km in around 5 or 5 and half hours.
Luna and Angela are competitors in a running competition. Both are leading the race and enter at the same time the last 30 meters. Angela enters the final segment runnning at 4 m/s and "applies" an acceleration of 2 m/s2 while Luna enters the final segment at 3m/s but "applies " an acceleration of 3 m/s2. (a) Who finishes the race first? (Do the calculations) (b) Who is running faster at the end of the race?
Answer:
(a) Luna
(b) Luna
Explanation:
(b)
The final speed can be found by using the third equation of motion:
[tex]2as = v_f^2 - v_i^2\\[/tex]
where,
a = acceleration
s = distance covered
vf = final speed
vi = initial speed
For Angela:
a = 2 m/s²
s = 30 m
vi = 4 m/s
vf = v_fa
therefore,
[tex]2(2\ m/s^2)(30\ m) = (v_{fa})^2 - (4\ m/s)^2\\v_{fa}^2 = 120 m^2/s^2 + 16\ m^2/s^2\\v_{fa} = 11.66\ m/s\\[/tex]
For Luna:
a = 3 m/s²
s = 30 m
vi = 3 m/s
vf = v_fl
therefore,
[tex]2(3\ m/s^2)(30\ m) = (v_{fa})^2 - (3\ m/s)^2\\v_{fa}^2 = 180 m^2/s^2 + 9\ m^2/s^2\\v_{fa} = 13.74\ m/s\\[/tex]
Therefore, Luna will be running faster at the end of the race.
(b)
To calculate the time of completion we will use the first equation of motion:
[tex]v_f = v_i + at[/tex]
FOR ANGELA:
[tex]11.66\ m/s = 4\ m/s + (2\ m/s^2)t_a\\t_a = \frac{7.66\ m/s}{2\ m/s^2}\\\\t_a = 3.83\ s[/tex]
FOR LUNA:
[tex]13.74\ m/s = 3\ m/s + (3\ m/s^2)t_l\\t_l = \frac{10.74\ m/s}{3\ m/s^2}\\\\t_l = 3.58\ s[/tex]
Hence, LUNA finishes the race first.

Calculate the force exerted by a boxing glove on an opponent's face, if the glove and face compress 8.50 cm during a blow in which the 7.00-kg arm and glove are brought to rest from an initial speed of 10.0 m/s. Give your answer in Newtons, do not include the unit in your answer.
Answer:
F = 4117.64
Explanation:
First, we will calculate the acceleration of the hand, by using the third equation of motion:
[tex]2as = v_f^2 - v_i^2\\[/tex]
where,
a = acceleration = ?
s = distance covered = compression = 8.5 cm = 0.085 m
vf = final speed = 0 m/s
vi = iniial speed = 10 m/s
Therefore,
[tex]2a(0.085\ m) = (0\ m/s)^2-(10\ m/s)^2\\a = - 588.23\ m/s^2[/tex]
negative sign hows deceleration.
Now, we will calculate the force exerted by the hand:
[tex]F = ma = (7\ kg)(588.23\ m/s^2)\\[/tex]
F = 4117.64 N

As Jack pulls his wagon down the street it moves faster and faster. Jill, sitting a few meters ahead on the sidewalk, wants to slow Jack's wagon down so that it travels with a constant speed. How can Jill accomplish her goal? A) Push the wagon with a force greater than Jack. B) Push Jack away from the wagon so that he is no longer pulling it. C) Pull on the wagon in the opposite direction with twice Jack's force. D) Push the wagon in the opposite direction at a constant force less than Jack.
Answer:
The correct answer is NONE the two forces must be equal and of opposite direction, the closest answer is D
Explanation:
In this exercise it is indicated that Jack pushes a car, it is desired that Jill pushes the car so that the speed is constant
take as positive the direction of Jack's thrust
F_jack - F_jill = 0
F_jill = F_jack
therefore the push of the two must be equal and Jill's push must have the opposite direction to Jack's push.
The correct answer is NONE the two forces must be equal and of opposite direction, the closest answer is D

What is the quality of the sound of an ambulance's siren when it moves toward a stationary hearer? What is the quality of the sound of an ambulance's siren when it moves away from a stationary hearer?
Answer:
A) As the ambulance's siren moves toward a stationary hearer, the quality of sound will have a higher pitch
B) As the ambulance's siren moves away from a stationary hearer, the quality of sound will have a lower pitch.
Explanation:
From Doppler effect, the closer the source of sound gets to the observer, the higher the frequency and in turn the higher the pitch.
Meanwhile, the farther a source goes from an observer, the lower the frequency of the sound and also the lower the pitch.
Thus, as the ambulance's siren moves toward a stationary hearer, the quality of sound will have a higher pitch.
As the ambulance's siren moves away from a stationary hearer, the quality of sound will have a lower pitch.
Answer:
a. The quality of the sound would have a high pitch and thus be loud.
b. The quality of the sound would have a low pitch and thus would have a lower volume than the sound from the source.
Explanation:
Using the formula for Doppler shift f' = (v ± v')f/(v ± v") where v = speed of sound in air, v'= speed of hearer = 0 m/s (since he is stationary), v" = speed of ambulance and f = frequency of sound from ambulance
So, f' = (v ± v')f/(v ± v")
f' = (v ± 0)f/(v ± v")
f' = vf/(v ± v")
a. What is the quality of the sound of an ambulance's siren when it moves toward a stationary hearer?
Since the source (ambulance) moves towards the detector, (hearer), we would get an upwards shift in frequency. (Since our denominator has to be a minimum, so we use the minus sign for v"). So, the quality of the sound would have a high pitch and thus be loud.
b. What is the quality of the sound of an ambulance's siren when it moves away from a stationary hearer?
Since the source (ambulance) moves away the detector, (hearer), we would get a downward shift in frequency. (Since our denominator has to be a maximum, so we use the plus sign for v"). So, the quality of the sound would have a low pitch and thus would have a lower volume than the sound from the source.
Two identical resistors connected in series have an equivalent resistance of 4 ohms. The same two resistors, when connected in parallel, have an equivalent resistance of:
Answer:
1 ohm
Explanation:
since there are two identical resistors, one resistor will be
R = [tex]\frac{4}{2}[/tex] =2ohm [ proven as in series [tex]R_{e} = 2 + 2 = 4ohm[/tex] ]
to calculate the equivalent resistance when in parallel:
[tex]\frac{1}{R_{e} } = \frac{1}{R_{1} } + \frac{1}{R_{2}}[/tex]
so,
[tex]\frac{1}{R_{e} } = \frac{1}{2} + \frac{1}{2}[/tex]
[tex]R_{e} = 1ohm[/tex]
Two identical resistors connected in series have an equivalent resistance of 4 ohms. The same two resistors, when connected in parallel, have an equivalent resistance of 1 ohm.
What is ohm?In a parallel circuit, voltage is thee same across each component in the circuit. The sum of the currents through each path is equal to the current from the source. However, the resistance cannot be added directly. It is calculated as:
1/Rt = 1/R1 + 1/R2 + 1/R3 1/Rt = 1/6.8 + 1/9.0 + 1/15
Rt = 3.08 ohms.
When resistors are connected in parallel, the equivalent resistance R will be less than the least resistance.
1/R = 1/R1 + 1/R2 + 1/R3 + 1/R4 + 1/R5
Since the 5 resistors are 10 ohms each, substitute them in to the formula
1/R = 1/10 + 1/10 +1/10 + 1/10 + 1/10
The LCM = 10
1/R = 5/10
Reciprocate both sides
R = 10/5 = 2 ohms
Therefore, Two identical resistors connected in series have an equivalent resistance of 4 ohms. The same two resistors, when connected in parallel, have an equivalent resistance of 1 ohm.

Resolver: Una bala de 0.8 de masa se mueve horizontalmente con una velocidad de 30 m/s y se introduce en un bloque de 4kg, inicialmente en reposo. ¿Cuál es la velocidad de la bala y el bloque después del impacto?
Answer:
La velocidad del sistema bala-bloque es 5 metros por segundo.
Explanation:
El enunciado tiene una omisión gramatical. La forma correcta es la siguiente:
Una bala de 0.8 kilogramos de masa se mueve horizontalmente con una velocidad de 30 metros por segundo y se introduce en un bloque de 4 kilogramos, inicialmente en reposo. ¿Cuál es la velocidad de la bala y el bloque después del impacto?
Esta situación es un caso clásico de colisión enteramente inelástica, en donde el sistema bala-bloque no tiene influencia de fuerzas externas, entonces la situación queda descrita por la siguiente ecuación:
[tex]m_{b}\cdot v_{b,o} = (m_{b}+m_{B})\cdot v[/tex] (1)
Donde:
[tex]m_{b}[/tex] - Masa de la bala, en kilogramos.
[tex]v_{b,o}[/tex] - Velocidad inicial de la bala, en metros por segundo.
[tex]m_{B}[/tex] - Masa del bloque, en kilogramos.
[tex]v[/tex] - Velocidad del sistema bala-bloque, en metros por segundo.
Si sabemos que [tex]v_{b,o} = 30\,\frac{m}{s}[/tex], [tex]m_{b} = 0.8\,kg[/tex] y [tex]m_{B} = 4\,kg[/tex], entonces la velocidad del sistema masa-bloque es:
[tex]v = \frac{m_{b}}{m_{b}+m_{B}}\cdot v_{b,o}[/tex]
[tex]v = 5\,\frac{m}{s}[/tex]
La velocidad del sistema bala-bloque es 5 metros por segundo.
