Suppose one of the global positioning system satellites has a speed of 4.42km/s at perigee and a speed of 3.64km/s at apogee. if the distance from the center of the earth to the satellite at perigee is 2.24×104 , what is the corresponding distance at apogee?

Explanation:

Given

Speed of satellite At Perigee

Speed at apogee

Distance from center to Perigee

Let be the distance of Apogee

According to Kepler's Second law angular Momentum is conserved

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.

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper.
