Which do you think requires more Work, lifting a 100 N load a vertical distance of 2 m or lifting a 10 N load a vertical distance of 4 m?
Answer:
Lifting 100 N 2 meters is much more work.
Explanation:
Remark
The formula is F * d = W
Givens
F = 100 N
D = 2 m
or
F = 10 N
D = 4 m
Solution
Work = 100 * 2
Work = 200 Joules
Work = 10 * 4
Work = 40 J

explain about the laws of reflection
Answer:
The law of reflection states that the angle of reflection equals the angle of incidence—θr = θi. The angles are measured relative to the perpendicular to the surface at the point where the ray strikes the surface.

Point P is located 1.7 m from fixed point charge q. The electric field Ē at point P is 8.6 x
10-2 N/C, directed away from the point charge. What is the magnitude of q? Let the
electrostatic constant k = 8.99 x 10°N • m²/C2.
O
A. 2.8 10-11 C
0
B. 4.8 * 10-11 C
O.C. -4.8 x 10-11 C
D. 1.5 x 10-10
Answer:
2.8 × 10^-11 C
Explanation:
The computation of the magnitude of q is shown below;
The electric field at point P because of point charge Q is provided by,
E = 8.6 × 10^-2 N/C
And, the separation between charge Q and P is r = 1.7m
Now According to the Coulomb's law,
E = kQ ÷ r²
8.6 × 10^-2 = 9 × 10^9 × Q ÷ (1.7)²
8.6 × 10^-2 × 2.89 ÷ 9 × 10^9 = Q
Q = (8.6 × 2.89 ÷ 9) × 10^-11
Q = 2.76 × 10^-11 C
= 2.8 × 10^-11 C

Ted lifts a 10N weight at a height of 1.5 m in 1 second. Johnny lifts a 10N weight at a height of 1.5 m in 2 second. Which statements are correct? A. Johnny and Ted did the same amount of work B. Ted did more work C. Johnny and Ted expanded the same power D. Ted expanded more power E Johnny did more work F. Johnny expanded more power
Answer:
he affirmations the correct ones are: A and D
Explanation:
To find out which expressions are correct, let's calculate the work and power done by each person
the expression for work is W = F and
the expression for power is P = W / t
In this case the work is positive because the beast is in the same direction of displacement.
Ted
W₁ = 10 1.5
W₁ = 15 J
P₁ = 15/1
P₁ = 15 w
Johnny
the job
W₂ = 10 1.5
W₂ = 15 J
the potential
P₂ = 15/2
P₂ = 7.5 w
therefore we see that the work of both is the same, but Ted developed twice as much power as Johnny
when resisting the affirmations the correct ones are: A and D
Camina con otro compañero, al mismo tiempo y al mismo paso. Quién se mueve tú o tu compañero? Razona tu respuesta
Answer:
Fricción.
Explicación:
Caminando con otro compañero al mismo tiempo y al mismo ritmo, el movimiento se produce debido a la fricción del suelo y la suela de los zapatos porque la fricción es la fuerza que ayuda en el movimiento de los objetos de un lugar a otro. Si no hay fricción entre el suelo y la suela de los zapatos, no podemos dar un paso por lo que podemos decir que la fricción nos mueve hacia adelante.
What is "Motion?"
Any physical movement or change of position of an object
When an object is square
When An object is standing still
[tex] \\ [/tex]
In physics, motion is the phenomenon in which an object changes its position over time. Motion is mathematically described in terms of displacement, distance, velocity, acceleration, speed, and time. One can also speak of motion of images, shapes, and boundaries.
Movement of any object from one position to another position with respect to the observer is called as Motion. Motion Along a Straight Line: When an object moves along a straight line, the motion of the object is called rectilinear motion. For example; motion of a car on highway.
In physics, motion is the change in position of an object with respect to its surroundings in a given interval of time. Motion is mathematically described in terms of displacement, distance, velocity, acceleration, and speed. An object's motion cannot change unless it is acted upon by a force.

The lower the efficiency of a ____, the ______ the percentage of energy that is degraded tp _____ energy.
Answer:
Machine; greater; thermal.
Explanation:
Conduction can be defined as the transfer of electric charge or thermal energy as a result of the movement of particles. When the conduction relates to electric charge, it is known as electrical conduction while when it relates to thermal energy, it is known as heat conduction.
In the process of heat conduction, thermal energy is usually transferred from fast moving particles to slow moving particles during the collision of these particles. Also, thermal energy is typically transferred between objects that has different degrees of temperature and materials (particles) that are directly in contact with each other but differ in their ability to accept or give up electrons.
Mathematically, the efficiency of a machine is given by the formula;
[tex] Efficiency = \frac {Mechanical \; advantage}{Velocity \; ratio} * 100 [/tex]
Hence, the lower the efficiency of a machine, the greater the percentage of energy that is degraded to thermal energy. We experience inefficiency in machines due to the fact that energy are being transformed or converted from one form to another.

If a car has a velocity of 85 km/hr, how long will it take to accelerate to 45 km/hr if the acceleration is -3 km/hr/sec?
Answer:
Time, t = 13.34 seconds.
Explanation:
Given the following data;
Initial velocity, u = 85km/hr to meters per seconds = 85*1000/3600 = 23.61 m/s
Final velocity, v = 45km/hr to meters per seconds = 45*1000/3600 = 12.5 m/s
Acceleration, a = -3 km/hr/sec to meters per seconds square = -3*1000/3600 = -0.833m/s²
To find the time;
Acceleration = (v - u)/t
-0.833 = (12.5 - 23.61)/t
-0.833t = -11.11
t = 11.11/0.833
Time, t = 13.34 seconds.

If a cliff jumper leaps off the edge of a 100m cliff, how long does she fall before hitting the water? (assume zero air resistance)
Hello,
QUESTION)Assuming that the initial velocity of the jumper is zero, on Earth any freely falling object has an acceleration of 9.8 m/s².
✔ We have : a = v/Δt = ⇔ Δt = v/a
Δt = (√2xgxh)/9,8 Δt = (14√10)/9,8Δt ≈ 4,5 sIf a cliff jumper leaps off the edge of a 100 m cliff , then she would have fallen 4.51 seconds before hitting the water.
What are the three equations of motion?There are three equations of motion given by Newton,
v = u + at
S = ut + 1/2 × a × t²
v² - u² = 2 × a × s
As given in the problem If a cliff jumper leaps off the edge of a 100 m cliff, then we have to find out how long she falls before hitting the water.
By using the second equation of the motion,
S = ut + 1/2 × a × t²
100 = 0 + 0.5 × 9.8 × t²
t² = 100 / 4.9
t = 4.51 seconds
Thus, If a cliff jumper leaps off the edge of a 100 m cliff, then she would have fallen 4.51 seconds before hitting the water.

A)This part controls the amount of light entering the eyes. A= Iris B= Pupil Give reason for your answer.
Answer:
Iris
Explanation:
Iris can be described as a part of the eyes which regulates the amount of light that enters the eye. The iris is made up of various muscles that control the size of the pupil
When a person is in a well-lighted room, the iris decreases the size of the pupil so that a low amount or medium amount of light is absorbed into the pupil. Also when an individual steps into a dark room the iris increases the size of the pupil so that a high amount of light penetrates the pupil.
Hence without the iris the amount of light that enters the eye cannot be controlled.

Why are very high temperatures and pressures required for fusion to occur?
to generate the neutrons that are needed to break the nuclei
to overcome the repulsion between the protons in the nuclei that join
to maintain the proper conditions to keep the chain reaction going
to keep the uranium fuel separate from the control rods
Answer:
so as to over come the repulsion between the protons in nuclei that join
Explanation:
it requires high temperature so that the nucleus starts moving at rapid speed which in turn increases their kinetic
In nuclear reactions, very high temperatures and pressures required for fusion to occur so as to to overcome the repulsion between the protons in the nuclei that join.
What are nuclear reactions?There are two types of nuclear reactions which are nuclear fusion and nuclear fission .They involve the combination and disintegration of the element's nucleus respectively.
In nuclear fission, the nucleus of the atom is bombarded with electrons of low energy which splits the nucleus in to two parts .Large amount of energy is released in the process.It is used in nuclear power reactors as it produces large amount of energy.
In nuclear fusion,on the other hand, is a reaction which occurs when two or more atoms combine to form a heavy nucleus.Large amount of energy is released in the process which is greater than that of the energy which is released in nuclear fission process.
