The force that the spring exerts is = 1.31 N
<h3>How can we calculate the force that the spring exerts?</h3>
The spring force in the spring depends on the spring's displacement and the force constant of the particular spring. The below expressions show the force that the spring exerts,
![F=kx](https://tex.z-dn.net/?f=F%3Dkx)
Here, we are given,
k= The spring constant of a spring = 8.75 N/m.
x= The displacement of the string is = 0.150 m
Now, we replace the known values in the above equation, we can find :
![F=kx](https://tex.z-dn.net/?f=F%3Dkx)
Or, ![F= 8.75 \times 0.150](https://tex.z-dn.net/?f=F%3D%208.75%20%5Ctimes%200.150)
Or, ![F= 1.3125 N](https://tex.z-dn.net/?f=F%3D%201.3125%20N)
Or, F≈ 1.31 N
Now, from the above calculation we can conclude that the force that the spring exerts is 1.31 N.

Energy is given off because it loses it by emitting photons/light.
Answer:
(a) Brightness if the bulb will reduce.
(b) The bulb will remain the same
(c) The brightness of the bulb will increase
The direction of friction force is always the opposite of the direction of the movement.
In this problem, we have an applied force of 20N and this creates a movement. Then, the friction comes in and applies a force of 2.4N.
Because they are in different directions, we need to subtract them:
![20 - 2.4 = x \\ \\ x = 17.6](https://tex.z-dn.net/?f=20%20-%202.4%20%3D%20x%20%5C%5C%20%20%5C%5C%20x%20%3D%2017.6)
We don't know the direction because there is no picture (at least I can't see ☺️). But the movement will be to the direction of the 20N.
