Asmall mass m hangs at rest from a vertical rope of length ℓ that is xed to the ceiling. a force then pushes on the
mass, perpendicular to the taut rope at all times, until the rope is oriented at an angle θ = θ0 and the mass has been
raised by a vertical distance h. assume the force’s magnitude f is adjusted so that the mass moves at constant
speed along its curved trajectory. show that the work done by during this process equals mgh, which is equivalent to the amount of work it takes to slowly lift a mass m straight up by a height h. [hint: when the angle is increased by dθ (in radians), the mass moves along an arc length ds = ℓ dθ.]

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.

the moon affects the earth gravitation ally, causing certain motions of that body and also producing tides in its ocean and atmosphere. the tidal wave in our atmosphere is, however, far too minute to be an effective cause in any known meteorological phenomenon.

does anyone know or what?

your answer is, orbit around the nucleus
