The object shown is moving in a horizontal, uniform, circular motion while on a rope. How does the centripetal force compare if the mass and radius stay constant, but the tangential velocity is changed from 2 m/s so that it spins at 4 m/s?
2 m/s

answer: the correct answer id option(d).

explanation:

snell's law refraction:

the angle of refraction =

the angle of incidence =

refractive index of air = = 1

refractive index of glycerol = 1.47

from the given options, the most closest answer to 63.72° is 65° of option (d).

answer; /// the above statement is (true);

are there options? cause you ain’t. real specific

no. dot product   =0 when vecs at right angles
