lesha says that a ball dropped from a height of 3.0 meters would have less than 96
joules of kinetic energy when it hits the ground. Is she correct and why?
She is correct because the higher the ball is dropped from, the
A
less kinetic energy it will have when it hits the ground
She is correct because the higher the ball is dropped from the
greater kinetic energy it will have when it hits the ground
She is incorrect because the higher the ball is dropped from the
greater kinetic energy it will have when it hits the ground.
D
She is incorrect because the higher the ball is dropped from the
less kinetic energy it will have when it hits the ground.

the body's situation won't change the forces are equal opposit and on the same body

get the total number of pieces of fruit and divide it by 4 to get the average. the result is the answer to the problem. 14 total number of fruits and there are 4 members. 14 divided by 4 is equals to 3.5.

you'd use the equation that establishes a relationship between  energy  and  wavelength, which looks like this

e=h⋅cλ, where

λ  - the wavelength of the photon; c  - the speed of light, usually given as  3⋅108m/s; h  -  planck's constant, equal to  6.626⋅10−34j s

plug the value you were given for the energy of the photon in the above equation to get the wavelength

e=h⋅cλ⇒λ=h⋅ce

λ=6.626⋅10−34js⋅3⋅108ms−1.257⋅10−24j=1.581⋅10−1m
