Answer:
ac = 124.6 m/s²
Explanation:
When an object executes a uniform circular motion, acceleration is produced in it due to a change in its direction during the motion. This acceleration is called the centripetal acceleration. The formula used to find this acceleration is given as follows:
where,
ac = centripetal acceleration = ?
v = speed = 9 m/s
r = radius = 0.65 m
Therefore,
<u>ac = 124.6 m/s²</u>
The ranges of frequency are:
UVA:
UVB:
Explanation:
The relationship between frequency and wavelength for an electromagnetic wave is the following:
where
f is the frequency
is the speed of light
is the wavelength
For the UVA, the range of wavelength is 320 nm - 400 nm, so
So the corresponding frequencies are
For the UVB, the range of wavelength is 280 nm - 320 nm, so
So the corresponding frequencies are
So the ranges of frequency are:
UVA:
UVB:
