So, if you have a a radius of 16 m, and it takes 12.56 seconds to travel circle, what is the centripetal acceleration? a =
m/s^2

How does the amount of energy required to hold each proton and neutron in the nucleus compare to the energy released when they are removed?

Two polarizers are oriented at 70∘∘ to one another. unpolarized light falls on them. what fraction of the light intensity is transmitted?

Unpolarized light of intensity so passes through two sheets of polarizing material whose transmission axes make an angle of 60∘ with each other as shown in the figure. what is the intensity of the transmitted beam, st?
