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

answer: d. a cme increases the amount of energy in the solar wind

explanation:

coronal mass ejections, also called cmes, are large clouds of plasma and magnetic field that erupt from the sun. only when the cloud is aimed at earth will the cme hit earth and therefore cause impacts. high-speed solar wind streams come from areas on the sun known as coronal holes.

real, smaller and upside-down.   so the answer should be b.
