Answer:
I think it should be D
Explanation:
This is because the arrow pointing right is bigger than the arrow pointing left. Hence we can conclude the the force acting on the right is greater and hence it is accelerating
Work can be calculated with the equation: Work = Force × Distance. The SI unit for work is the joule (J), or Newton. meter (N. ... One joule equals the amount of work that is done when 1 N of force moves an object over a distance of 1 m

Answer:
1. B- kinetic to gravitational potential energy
2. A-gravitational to kinetic energy
Explanation:
When the train goes up the hill, the kinetic energy decreases (the speed decreased) due to the pull of gravity.
When the train goes down the hill, the speed increases (kinetic energy increases) and since the object is coming downwards the gravitational potential energy decreases
Answer:
B. solar energy → electric energy → light and heat energy
Explanation:
The solar energy received from the solar rays is transformed into electrical energy, through a photovoltaic process that is part of the solar panel and other elements. Then the electric energy generates currents that pass through the electrical circuit and this transformation generates light in electric bulbs. Since energy conversion processes are never 100% efficient for the electric energy in the bulb is transformed into heat, for that reason the electric bulb emits part of its energy in the form of light and heat.
