Please help the fossil evidence show is useful for supporting the idea of continental drift because-

A ) The fossil show how the animals could swim from one continent to the next.
B ) The fossil are found in layers of sedimentary rocks that were deposited on separate continents.
C ) The fossil show that the animals once lived on a joined super continent.
D ) Fossil can be formed in a relatively short amount of time.

When person is standing on a bathroom scale

then the reading of the scale is the measurement of normal force on the scale

so here we can see that normal force is 0.64 times the weight of the person

This shows that the normal force is less than the weight

It shows that elevator must have to accelerated downward direction

so here we will use the force equation

here we know that

also we know that

now we have

so acceleration of elevator will be 3.53 m/s^2 in downward direction
