Answer:

Explanation:
In a uniform circular motion, since a complete revolution represents 2π radians, the angular velocity, which is defined as the angle rotated by a unit of time, is given by:

Here T is the period, that is, the time taken to complete onee revolution:

Replacing (2) in (1):

The relationship between frequency and wavelength for an electromagnetic wave is

where
f is the frequency

is the wavelength

is the speed of light.
For the light in our problem, the frequency is

, so its wavelength is (re-arranging the previous formula)
Answer:
l=3.5 x 10^-10m
Explanation:
just toook the test got it right good luck!
Answer:
A
Explanation:
potential energy is energy due to position
shm
displacement is A*sin 2pi f t
vel =( A*2*pi*f*)*cos 2 pi f t
accn =-( A*2*pi*f*)^2*sin 2 pi f t
accn = (0.01*2*3*5)
accn = (0.01x30)^2=9
