Answer:
The tendency of an object to resist changes in its state of motion varies with mass. Mass is that quantity that is solely dependent upon the inertia of an object. The more inertia that an object has, the more mass that it has. A more massive object has a greater tendency to resist changes in its state of motion.
Form of body conditioning endurance training or resistance training using high intensity
The answer is C. Infrared Rays.
Option D, the sentence that best describes the object is the material of the object can be magnetized.
<h3>Atoms of magnetic material</h3>
The direction of the magnetic fields of the atoms that make up an object is always aligned towards the north pole or south of the material.
Objects that are made of unmagnetised materials such iron, cobalt and nickel are attracted to either pole of a magnet, but not repelled.
The diagram given shows unmagnetised material, and hence the material of the object can be magnetized.

<h2>The work done is 3 S</h2>
Explanation:
A constant force of 4.9 N is applied on the body in the horizontal and positive direction .
The object moves in x-y plane making an angle of 130° with horizontal .
Thus the work done can be calculated by the dot product of force and displacement S ( say )
Thus the work done = F . S = F S cos 130
= - 4.9 x 0.6 x S = - 3 S approx
