Two satellites are in orbit around the same planet. satellite a has a mass of 1.5 x 10^2 kg and satellite b has a mass of 4.5 x 10^3 kg. the mass of the planet is 6.6 x 10^24 kg. both satellites have the same orbital radius of 6.8 x 10^6 m. what is the difference in the orbital periods of the satellites?

The difference in the orbital periods of the satellites is zero.

Explanation:

Given data,

The mass of the planet A is, m = 1.5 x 10² kg

The mass of the planet B is, m' = 4.5 x 10³ kg

The mass of the planet is, M = 6.6 x 10²⁴ kg

The orbital radius of the satellites are, R = 6.8 x 10⁶ m

The orbital period of the satellite is given by,

From the above equation, it is evident that the period of the satellite is independent of the mass of the satellite.

Since the radius of the orbit of the satellites A and B are the same, the difference in the orbital periods of the satellites is zero.

freezing

deposition

condensation

explanation;

melting also called fusion is the process where solid becomes liquid, sublimation is the process where solid becomes gaseous without first changing to liquid, deposition involves change from gaseous to solid state, freezing involves change from liquid to solid, boiling or evaporation involves change of liquid to gaseous state, while condensation is the change from gaseous state to liquid state.

endothermic reactions involves absorption of heat from the surroundings or the environment while exothermic reactions involves loss of heat energy to the surroundings.

in this case, sublimation, evaporation and melting are endothermic reactions (gain energy from the environment) while, freezing, deposition and condensation are exothermic (loss of energy to the surroundings) reactions.
