Rotation. The Earth rotates around the sun on it’s axis. Depending how far north or south you live, and the angle of the sun at different times of year gives you the amount of daylight or darkness you will receive. So the length of day or night depends on how much the sun is able to reach the spot on a round object such as the planet Earth.

Calculate the wavelength of the electromagentic waves with the given frequencies, and determine the type of electromagnetic radi
ololo11 [35]

To develop this problem we require the concepts related to wavelength and its expression to calculate it.

The wavelength is given by

\lambda =\frac{c}{f}

Where,

c=3*10^8 m/s light velocity

f = frequency.

Our values are given by,

f_1=4.38*10^{14}Hz

f_2= 4.14*10^{20}Hz

f_3 = 3.24*10^{12}Hz

Then,

\lambda_1=\frac{3*10^8}{4.38*10^{14}}= 6.8493*10^{-7}m Visible

\lambda_2=\frac{3*10^8}{4.14*10^{20}}= 7.24*10^{-13}m Gamma Ray

\lambda_3=\frac{3*10^8}{3.24*10^{12}}= 9.259*10^{-5}m Infrared

<em>*Note the designation on the type of rays that are, can be found in consulted via On-line or in the optical books referring to the electromagnetic spectrum table with their respective ranges.</em>

A compressed spring has elastic potential energy. Please select the best answer from the choices provided T F
riadik2000 [5.3K]

Answer: True

Explanation:

As the spring is compressed, it acumulates energy, and the spring "wants to release that energy". This acumulated energy, (potential energy) is called "elastic potential energy" because of the elastical nature of the spring, that when compressed it wants to return to the original shape. So the sentence is true
