A large artery has a diameter of mm. This artery divides into two identical smaller arteries, the velocity of the blood in the smaller arteries is the same as the velocity of the blood in the larger arteryWhat is the diameter of the smaller arteries ?

unbalanced force

explanation:

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

i think the answer is a and b

i wish you luck
