Answer:
Inertia is the resistance of any physical object to any change in its velocity. This includes changes to the object's speed, or direction of motion. An aspect of this property is the tendency of objects to keep moving in a straight line at a constant speed, when no forces act upon them.

What is the multiple choice???
Answer:
time period is increased so the clock will become SLOW
Explanation:
As we know that the time period of the simple pendulum is given by the formula

here we know that
L = distance of the pendulum bob from the hinge
g = acceleration due to gravity
now here the bob slide down so that the length of the pendulum is being increased
so time period T of the pendulum is also increased
so here the pendulum will take more time to oscillate or to complete one oscillation
so clock will become SLOW
The efficiency of the engine at the given useful energy and input energy is 28%.
The given parameters:
- <em>Input energy of the engine, = 125 J</em>
- <em>Useful energy of the engine, 35 J</em>
The efficiency of the engine is defined as the ratio of the output energy (useful energy) to the input energy and it is calculated as follows;

Thus, the efficiency of the engine at the given useful energy and input energy is 28%.
