Answer:
e. All of these statements are false.
Explanation:
As we know that heat transfer take place from high temperature to low temperature.
It is possible to convert all work into heat but it is not possible to convert all heat in to work some heat will be reject to the surrounding.
The first law of thermodynamics is the energy conservation law.
Second law of thermodynamics states that it is impossible to construct a device which convert all energy into work without rejecting the heat to the surrounding.
By using heat pump ,heat can transfer from cooler body to the hotter body.
Therefore all the answer is False.
Answer:
3600 J
Explanation:
Kinetic energy of an object is the energy posses by an object solely due to its motion.
It can also be defined as the amount of work that can be done when an moving object come to test.
Kinetic energy of an object can be calculated by the equation,
K.E. = ½mv²
Where m = mass, v = velocity
So you get,
K.E. = ½×0.5×(120)² = 3600 J
The power output is, 2800 watt. Power is defined as the rate of the work done.
<h3>What is force?</h3>
Force is defined as the push or pull applied to the body. Sometimes it is used to change the shape, size, and direction of the body. Force is defined as the product of mass and acceleration. Its unit is Newton.
The power output is found as;
Hence,the power output is, 2800 watt.

No, Alec has not.
The force due to gravity is the same on all objects, regardless of shape and size. The acceleration caused by this force is 9.81 m/s². So if there are two identical pieces of paper, both will experience an equal force of gravity.
The difference in the papers' flight paths is due to the greater air resistance that the flat paper experiences. If the same experiment were to be repeated in a vacuum chamber, both of the pieces of paper would fall at the same rate
