A 2.15 kg block of iron at 415 C is put in 0.625 kg of water at 15.0 C. They come to equilibrium at 100C, and some (but not all) of the water boils off. How much steam boils off? PLEASE HELP

if you answer my question i will answer yours

double the distance = divide strength by 4

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
