The correct answer is  "c".  it is "c" because melting is an endothermic change, and endothermic get's energy from surroundings. 

Because the sun is the biggest and if the sun orbits the earth we will be dead probably

The force is push or pull

107.1 mhz has higher energy photons. the photon energy increases directly proportional to frequency. however if the station operating on 90.5 mhz transmitter's power is 1.184 times or higher than that of the station operating on 107.1 mhz transmitter's power, then the 90.5 mhz signal will have higher energy because the additional photons makeup the difference. the total energy in electromagnetic radiation is the product of the energy per photon and the number of photons (i.e. amplitude of the wave) in the radiation.
