Left block: f k=0.462(2.45N)=1.13N. The maximum static friction force would be larger, so the spring force would produce no motion of this block or the right-hand block, which could feel even more friction force. For both, a=0.
<h3>What is kinetic energy?</h3>
- A particle or an item that is in motion has a sort of energy called kinetic energy. An item accumulates kinetic energy when work, which involves the transfer of energy, is done on it by exerting a net force.
- Kinetic energy comes in five forms: radiant, thermal, acoustic, electrical, and mechanical.
- The energy of a body in motion, or kinetic energy (KE), is essentially the energy of all moving objects. Along with potential energy, which is the stored energy present in objects at rest, it is one of the two primary types of energy.
- Explain that a moving object's mass and speed are two factors that impact the amount of kinetic energy it will possess.
(c) 0.462:
Frictional force is the one which opposes the motion of an object. Here, the force of kinetic friction on the heavier block is greater than the force exerted by the spring on the block. Hence, the block will not move and the acceleration is zero.
F k=0.462(2.45N)=1.13N for the left block. Because the maximum static friction force would be higher, neither this block nor the right-hand block, which might experience even greater static friction force, would move in response to the spring force. A=0 for both.

Answer:
![E=54V/cm](https://tex.z-dn.net/?f=E%3D54V%2Fcm)
between the plates.
Explanation:
The equation for change of voltage between two points separated a distance d inside parallel conducting plates (<em>which have between them constant electric field</em>) is:
![\Delta V=Ed](https://tex.z-dn.net/?f=%5CDelta%20V%3DEd)
So to calculate our electric field strength we use the fact that the potential 8.8 cm from the zero volt plate is 475 V:
![E=\frac{\Delta V}{d}=\frac{475 V}{8.8cm}=54V/cm](https://tex.z-dn.net/?f=E%3D%5Cfrac%7B%5CDelta%20V%7D%7Bd%7D%3D%5Cfrac%7B475%20V%7D%7B8.8cm%7D%3D54V%2Fcm)
And we use the fact that the plates are 9.2cm apart to calculate the voltage between them:
![\Delta V=Ed=(54V/cm)(9.2cm)=496.8V](https://tex.z-dn.net/?f=%5CDelta%20V%3DEd%3D%2854V%2Fcm%29%289.2cm%29%3D496.8V)
Answer:
4. Energy can be created and destroyed
Explanation:
Reason being it tells you a part of the definition of energy while all the other answers tell you why the sun is not the only source of energy.
The force is zero force
Inertia keeps objects traveling in a straight line until some net non zero force causes it to change course and/or speed
