Which of the following is the shortest wavelength of light? Group of answer choices blue visible light gamma rays radio red visible light x-rays

the area between the graph and the t axis

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
