AYUDAAAAAAA Un ciclista de montaña se mueve cuesta abajo por la pendiente, si acelera a 3 m/s2 y se demora en bajar 15 minutos (900 segundos) ¿Qué distancia recorre? AYUDENME PORFAVOOOR
The question is: HELPAAAAAAA A mountain biker moves downhill if he accelerates at 3 m / s2 and takes 15 minutes (900 seconds) down, how far does he travel? HELP ME PLEASE
Answer: The distance travelled by the mountain biker is 2430 km.
Explanation:
Given: Acceleration = [tex]3 m/s^{2}[/tex]
Time = 15 minutes (900 sec)
Displacement = ?
Formula used to calculate the final velocity is as follows.
[tex]v = u + at[/tex]
where,
v = final velocity
u = initial velocity = 0 m/s (here)
t = time
a = acceleration
Substitute the values into above formula as follows.
[tex]v = u + a \times t\\v = 0 + 3 m/s^{2} \times 900 s\\= 2700 m/s[/tex]
The relation between velocity (speed) and distance is as follows.
[tex]Speed = \frac{Distance}{time}\\2700 m/s = \frac{Distance}{900 s}\\Distance = 2430000 m (1 m = 0.001)\\= 2430 km[/tex]
Thus, we can conclude that distance travelled by the mountain biker is 2430 km.

Which is not true about the role of gravity in the formation of planets?
Dust and gas particles that were attracted to each other began to rotate into a protoplanetary disk.
Gravity between planetesimals caused them to join together into conglomerate clumps. Our solar system is the only place in the universe where gravity played a key part in the formation of planets.
Gravity of larger objects in orbit around the sun attracted, and cleared the orbital path of, smaller planetesimals, gas, and dust.
Our solar system is the only place in the universe where gravity played a key part in the formation of planets.

It increases.
The force of gravity between two masses increases as they are moved closer together.
option D.
What is Newton's law of universal gravitation?Newton's law of universal gravitation states that the magnitude of the force between two masses is directly proportional to the product of the two masses and inversely proportional to the square of the distance between them.
F = GM²/R²
where;
M is massR is the distance between the massesThe force of gravity between two masses increases as they are moved closer together. This is because gravity is an attractive force that depends on the distance between the masses.

9. Bryce drove his car 10 km from his house to Belle Plaine. It took him 8 minutes. He got stopped at a long
traffic light on the return home and so he took 2 minutes longer on the return trip. What was Bryce's average
speed in km per minute? (3 pt)
Answer:
2 km/minuteExplanation:
Here, we are asked to calculate the average speed in km/minute.
As we know that,
Average speed = Total distance ÷ Total time takenHere,
→ Total distance = 10 km + 10 km
Because, he first drove 10 km from his house to Belle Plaine and then he again came back to his house.→ Total distance = 20 km
→ Total time = 8 minutes + 2 minutes
→ Total time = 10 minutes
Substitute the values in the formula of average speed,
→ Average speed = Total distance ÷ Total time taken
→ Average speed = 20km ÷ 10 minutes
→ Average speed = 2 km per minuteA solid metal ball with a mass of 10.0 kg is placed on a smooth floor what force would be needed to accelerate the ball at a rate of 2.0 m/s2.

The diagram below shows a periodic wave. Which two points on the wave are 180 degrees out of phase?
Please explain as well, thanks so much
Answer:
A and C are 180 deg out of phase (opposite points on a 360 deg wave)
The two points on the periodic wave which are 180 degrees out of phase are point A and Point C.
When two points of wave are out of phase?The two points of a wave is said to be out of phase when they show up or down motion at different times.
If a point on the wave, say (X) is reached to the maximum or minimum point before the other point. Then these two points are said to be out of phase.
Also, when the points are 180 degree apart from each other. Which means if a point is in the crest of the wave and other is on the through.
The diagram below shows a periodic wave. In this diagram,
A and I are the end points of the periodic wave.B,C,D,E,F and G are the other points on the periodic wave.Here, the point A and C are opposite point of each other. So they are 180 degrees out of phase.Hence, the two points on the periodic wave which are 180 degrees out of phase are point A and Point C.

What is the intensity of sound produced by an elephant's call if it has a power of 0.45 W and you are standing 32.5 m away from the lumbering beast
Answer:
I = 1.36 x 10⁻⁴ W/m²
Explanation:
The intensity of the sound produced by the Elephant can be calculated by using the following formula:
[tex]I = \frac{P}{A} \\\\[/tex]
where,
I = Intensity of sound = ?
P = power of sound = 0.45 W
A = area = πr² = π(32.5 m)² = 3318.3 m²
Therefore,
[tex]I = \frac{0.45\ W}{3318.3\ m^2} \\\\[/tex]
I = 1.36 x 10⁻⁴ W/m²
According to the graph, how many atoms would remain after two half-lives?
20 atoms
80 atoms
40 atoms
50 atoms
Answer:
Let No be initial no of atoms
N = N0 / 2 after 1 half-life
N = N0 / 4 after 2 half-lives
So after 2 half-lives 20 of the 80 atoms remain

A resistor is connected to a 36v power supply. An ammeter measures a current of 2.0 A going through it. Determine the resistance in ohm
R = 18 ohms
Explanation:
Given:
V = 36 volts
I = 2.0 A
R = ?
Use Ohm's law to solve for the resistance:
V = IR
or
R = V/I
= (36 volts)/(2.0 A)
= 18 ohms
How does the current in a circuit change if the resistance is doubled? The current is halved. The current is doubled. The current is multiplied by four. The current stays the same.
Answer:
The current is halved
Explanation:
The relationship between the current and the resistance is given by Ohm's Law, as follows:
[tex]V = IR\\I = \frac{V}{R}[/tex]
where,
V = Voltage
I = Current
R = Resistance
Therefore, if we double the resistance:
[tex]I' = \frac{V}{2R}\\\\I' = \frac{1}{2}I[/tex]
Hence the correct option is:
The current is halved

How much work is done by 0.070 m3 of gas, when the volume remains constant with pressure of 63 x 105 Pa?
Answer:
W = 0 J
Explanation:
The amount of work done by gas at constant pressure is given by the following formula:
[tex]W = P\Delta V[/tex]
where,
W = Work done by the gas
P = Pressure of the gas
ΔV = Change in the volume of the gas
Since the volume of the gas is constant. Therefore, there is no change in the volume of the gas:
[tex]W = P(0\ m^3)\\[/tex]
W = 0 J

A ___ is a large ball of gas that generates its own energy. This energy is created by the fusion of ___ atoms to make ___.
Answer:
Star, hydrogen and energy
Explanation:
A star is a large ball of gas that generates its own energy by fusing hydrogen atoms to make helium. It is held together by its own gravity. This process emits a tremendous amount of energy, and some of the energy is in the form of light.
The energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. When the core is hot enough, nuclear fusion commences. Fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.
