)a stone is dropped from the top of a cliff. it is seen to hit the ground below after 3.55 s. how high is the cliff?

We use kinematic equation of motion,

Here, s is distance traveled, u is the initial velocity, t is time taken and g is acceleration due to gravity.

Given, .

We take,   because stone has no initial velocity.

Therefore,

Thus,  the height of cliff is approximately 61.75 m.

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.
