You lift a 44 N box from the floor and place it on a shelf that is 1.5 m above the ground. How much work did you use in lifting the box?

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be

explanation:

considering the bohr theory, the type of connection that requires the transfer the answer conuldn't be right

find the surface area of the sphere to the nearest square unit. use a calculator.

a. 254 in.2

b. 64 in.2

c. 127 in.2

d. 1,018 in.2
