A75 kg box slides down a 25.0 degree ramp with an acceleration of 3.60 m/s^2.
find coefficient between the box and the ramp. what acceleration would a 175 kg box have on this ramp?

The coefficient and acceleration are 0.061 and 8.284 m/s².

Explanation:

Given that,

Mass = 75 kg

Angle = 25.0°

Acceleration = 3.60 m/s²

We need to find the force

Now, we need to calculate the parallel force

We calculate the friction force

If the box is moving in an angle, then the weight

If it is horizontally then

So, The normal force is

We need to calculate the coefficient between the box and ramp

Where, =friction coefficient

=frictional force

F''=normal force

Put the value into the formula

We need to calculate the acceleration

Hence, The coefficient and acceleration are 0.061 and 8.284 m/s².

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.

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
