Tennis balls with a diameter of 2.5 inches are sold in cans of three. The can is a cylinder. What is the volume of the space NOT
katrin2010 [14]
We know that
volume of a sphere=(4/3)*pi*r³------> volume of a tennis ball
for r=2.5/2-----> 1.25 in
volume of a sphere=(4/3)*pi*1.25³------> 8.18 in³
volume of 3 tennis ball=3*8.18-----> 24.54 in³

volume of a cylinder=pi*r²*h
r=1.25 in
h=2.5*3-----> 7.5 in
volume of a cylinder=pi*1.25²*7.5-----> 36.82 in³

<span>the volume of the space NOT occupied by the tennis balls=36.82-24.54
</span><span>the volume of the space NOT occupied by the tennis balls=12.28 in</span>³

the answer is

If light travels at 3. 108 m/s and its frequency is 6. 1015 Hz, then its wavelength is:
Sergio039 [100]

Answer:

5 * 10^{-8} m

Step-by-step explanation:

The speed of light is 3 * 10^8 m/s and its frequency is 6 * 10^{15} Hz.

The speed of light is given as:

c = λ * f

where λ = wavelength of light

f = frequency of light

Therefore, the wavelength is given as:

λ = c / f

=> λ = \frac{3 * 10^8}{6 * 10^{15}}

=> λ = 5 * 10^{-8} m

The wavelength of the light is 5 * 10^{-8} m
