Raindrops of mass 5*10 power-7 kg fall vertically in still air with a uniform speed of 3m/s If such drops are falling when the wind is blowing with a speed of 2m/s, what is the angle that the path of the drops make with the vertical? Determine the kinetic energy of the drops.

f=ma a/f/m a= 480/60 a = 8m/s/s that is quick wow

close lines strong magnet less close weaker

if they have a finite resultant

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
