It is approximately 238,900 miles away from Earth.
one disadvantage is that magnets the opposites attract so the same type of magnets like n+n will keep repelling unless you use the opposite side of the magnet the it will attract
Kinetic energy is the energy of an object due to its motion. An object sitting still isn't moving, therefore it has no kinetic energy. The statement in the question is false.
A heat pump is a device used to heat something, in this case water. Heat pump takes heat from colder object and transfers it to warmer object. This is opposite to <span>direction of spontaneous heat transfer which from warmer to colder object.
In this problem a room got colder while water got warmer. This is due to work done by heat pump. This is what is described in correct answer c).
a) is not correct because it shows </span>direction of spontaneous heat transfer. It also says that <span>Aleksei’s family purchased a new water heater and in description givne in a) it would mean that water got colder.
b) is not correct because if the </span><span>burning fuel increased the thermal energy in the air it would mean that this room got warmer than rest of house.
d) is not correct because burning fuel does not absorb </span><span>thermal energy. It releases it.</span>
