Aconcrete slab 20 m long and weighing 400,000 n is supported by one pillar. a 19,600 n car is parked 8 meters from one end, where should the pillar be so the slab is balanced?

let the distance of pillar is "r" from one end of the slab

So here net torque must be balance with respect to pillar to be in balanced state

So here we will have

here we know that

mg = 19600 N

Mg = 400,000 N

L = 20 m

from above equation we have

so pillar is at distance 10.098 m from one end of the slab

report!

explanation:

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."

no. bullets are macro objects. wave nature is for light waves, extremely tiny particles. if a light particle was the size of your finger, the bullet would be the size of the universe. so basically, that huge difference in size makes the wave nature of matter insignificant.
