1. T
2. F
3. T
4. sorry I am not sure about this one
5. T
Answer:
1) false
2)false
3)true
4)false
5)true
Explanation:
1)The statement a book lying on the study table has no energy if wrong because book has potential energy because of the gravitational force that pull the book in the downward direction.
2) The statement that the energy cannot be transformed from one form to another form is wrong because the law of conservation of energy states that energy can neither be created nor destroyed as it can only converted from one form of energy to another.
3)The statement that A book lying on the study A solar cell converts the light energy to electrical energy is correct as the Solar technologies convert sunlight into electrical energy either through photovoltaic (PV) panels or through mirrors that concentrate solar radiation.
4)The statement that Greater the mass of the body lower is the kinetic energy of the body is wrong because kinetic energy of a body is directly proportional to the mass of the body
5) The statement that The muscular energy is derived from the chemical energy stored in the food that we eat is correct
