A wheel, 0.2 m in radius starts from rest and accelerates uniformly to an angular velocity of 50 rads' in 5 sec. Find the angular acceleration and the angle turned through. [10 rads? 125 rad

it breaks and dirupture other materials and other sencews from the bottom

d) physical means can be used to separate the components of air.

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
