Suppose that she pushes on the sphere tangent to its surface with a steady force of FFF = 65 NN and that the pressured water provides a frictionless support. How long will it take her to rotate the sphere one time, starting from rest?

a, c, d, e are all applying about success strategies.

gravity

explanation:

radiation

explanation:

heat is transmitted by radiation

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
