Usually when heat is transferred to a substance, the temperature of the substance increases. However, while a substance is melting or boiling, its temperature does not change, even though heat is being transferred to it. What is the scientific term used for the heat transferred in this situation?

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards

can u provide the graph and if its not possible

then i can tell u the segment where the

average time interval starts degrading is the segment where the car is slowing down
