Angelina jumps off a stool. as she is falling, the earth’s gravitational force on her is larger in magnitude than the gravitational force she is exerting on the earth. 1. false 2. this may happen in many cases, but not in every case. 3. true 4. none of these 5. this may happen in a few cases, but it is very rare.

1. False

Explanation:

As per law of gravitational attraction force we know that

where we know that

= masses of two point mass

= distance between two masses

so here we know that as the force does not depend on individual mass but it will depend on the product of two masses

so here the gravitational force is same in magnitude on both the bodies

so when Angelina jumps off the stool the gravitational force on Earth and on Angelina must be of same magnitude

the best answer for these questions would be:

1.            c. is smaller

2.            d) concrete operational

3.            b) interaction with the environment – the children interact with their environment can them learn more.

4.            a) parents who reason openly with children can limit a child’s cognitive ability.
