Answer: No, the student does not do any work on the wall.
Explanation: The work is defined as the movement of an object done/caused by a force.
And it can be calculated as:
W = F*d
where W is work, F is force and d is the displacement of the object
In this case, the student is applying force on the wall, so we have the first part, but we also know that the wall does not move, so in this case, d = 0, which would imply that the work applied to the wall must be equal to zero
(because W = F*0 = 0)
So the answer is no, the student does not do any work on the wall.
The displacement of an object in relation to time is velocity.
Speed is similar, but it is actually the distance traveled in relation to time. The difference is that say if an object is spinning at one revolution per second, the speed of the edge is 'x' mps. The velocity on the other hand is 0 mps because the disk rotates at 1 rotation per second the displacement after one second is 0.
Answer with Explanation:
We are given that
Distance,r=0.27 m
Tangential speed=v=0.49 m/s
a.Angular speed ,
Using the formula
Time period,
b.Amplitude,A=Distance of small eraser from the center of a turnable =0.27 m
c.Maximum speed,
d.Maximum acceleration=

If the wall doesn't move, its mean that <u>the work he did is 0 J</u>.
<h3>Introduction</h3>
Hello my friend ! Here, I will help you. Alright, before it, I will to introduce to you about work (physics). In the world of physics, <u>work is the amount of force exerted to cause an object to move a certain distance from its starting point</u>. The amount of work will be proportional to the increase in force and increase in displacement. Amount of work can be calculated by this equation :
With the following condition :
- W = work (J)
- F = force (N)
- s = shift or displacement (m)
<h3>Proof</h3>
How about a stationary object like a wall pushed by Mr. Avalos ? Yes it is 0 J. Let's prove it!
Give :
- F = force of Mr. Avalos = 150 N
- s = displacement of wall = 0 m
- t = interval of the time = 60 s
Asked : W = work = ... J
Proven :
