A golf ball with a mass of 45 g is dropped from a height of 1 m. From last semester, you could figure out that its velocity right before it hits the ground is .44 m/s.

explanation:

v=uf/(u-f)

= 5.-10/(5+10) convex lens has negative focal length

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.

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.
