an army tank weigh more than 1000 kg and rests upon a continuous chain.why?

The weight of an army tank is very large. This weight will exert a large pressure on the ground due to which it wont be able to run on loose surface. It may be able to run on solid land but not on desert soil or loose marshy soil. Hence, it rests upon a continuous chain. This arrangement increases the area of contact with the ground. Due to this, the pressure reduces and the tank is able to move freely.

A boy throws a steel ball straight up. Consider the motion of the ball only after it has left the boy's hand but before it touches the ground and assume that forces exerted by the air are negligible. For these conditions, the force(s) acting on the ball is (are): a. A downward force of gravity along with a steadily decreasing upward force b. A steadily decreasing upward force from the moment it leaves the boy's hand until it reaches its highest point on the way down there is a steadily increasing downward force of gravity as the object gets closer to the earth c. Constant downward force of gravity along with an upward force that steadily decreases until the ball reaches it highest point on the way down there is only a constant downward force of gravity d. Constant downward force of gravity only
