Fusion occurs in the D. core of the Sun, where the pressure and temperature are very high.
This process happens in the very center of this star, which is known as the place where the temperature is the highest.
The motion would be best described as B) an up-and-down motion on the surface of the earth
Other characteristics that Nima can share with her students are as follows:
- Visible light ranges in wavelength of 400 - 700nm
- Visible light is between the ultraviolet and infrared rays of the EM spectrum.
<h3>What is visible light?</h3>
Visible light is one of the components of the electromagnetic spectrum (EM). It is the only part of the EM spectrum that is visible to human eyes.
According to this question, Nima has already shared this characteristics of visible light with her student.
Other characteristics that Nima can share with her students are as follows:
- Visible light ranges in wavelength of 400 - 700nm
- Visible light is between the ultraviolet and infrared rays of the EM spectrum.

Taking the distance of Tarzan from the ground before and after he makes the swing:
Ho (initial height) = L(1 - cos45) = 20 (1 - 0.707) = 5.86 meters
Hf (final height) = L(1 - cos30) = 20 (1 - 0.866<span>) = 2.68 meters
</span>
Difference in height = 5.86 - 2.68 = 3.18 meters
PE = KE
mgh = (1/2)mv^2
Solving for v:
v = sqrt (2*g*h)
v = sqrt (2*9.8*3.18)
v = 7.89 m/s
With Tarzan going that fast, it is likely that he will knock Jane off.
