A water pump takes water through 12m. Water is discharged at the surface at the rate of 2Kg/s, and the discharge speed of each drop is 3m/s. Find the minimum power of the pump

d

explanation:

i think the answer is d. but im not sure!

it is very well related to a lot of things but with my limited knowledge i can confidently say that the answer is space.

layers of the earth affect the waves and these effects are seen on instruiments such as seimometers

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
