Answer: A 60 g golf ball is dropped from a level of 2 m high. It rebounds to 1.5 m. Energy loss will be 0.29J
Explanation: To find the correct answer, we have to know more about the Gravitational potential energy.
<h3>What is gravitational potential energy?</h3>
- The energy possessed by a body by virtue of its position in gravitational field of earth is called gravitational potential energy.
- The gravitational potential energy of a body at a height h with respect to the height h will be,
- Expression for gravitational potential energy loss will be,
<h3>How to solve the problem?</h3>
- The total energy before the ball dropped will be,
- The total energy after when the ball rebounds to 1.5m will be,
- The total energy loss will be,
Thus, we can conclude that, the energy loss will be,0.294J.

I believe this question should be in Health, however, I'll answer it to the best of my ability.
Answer: Physical fitness.
Physical fitness can be achieved through a set diet, physical excersise (of course), rest, and many cardiovascular exercises. It is the ability of the body to successfully function efficiently during PA.
Voltage is given by the formula
V = IR (Ohms law)
where V is the Voltage
I is the current
and R is the Resistance
Here it is given that the current is I=11
Resistance is R =12
so plugging this in the formula
V = IR
V= 11 * 12
V= 132 Volts
So the Voltage for the given dryer is 132 Volts
