explanation:

considering the bohr theory, the type of connection that requires the transfer the answer conuldn't be right

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.

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
