Potential energy is the energy by virtue of object's height & kinetic energy by virtue of it's motion!
Hope this helps!
Answer:
r₂/r₁ = 1.82
Explanation:
The electric field due to a point charge, has the following expression:
For a distance r₁, the magnitude of the electric field is 395 N/C, so we can solve for r₁², as follows:
r₁² = (1)
For a distance r2, the magnitude of the electric field is 119 N/C, so we can solve for r₂², as follows:
r₂² =
We can find the quotient r₂/r₁, from (1) and (2):
r₂/r₁ = = 1.82
Explanation:
Since, it is given that one hand completes 3.19 vibrations in 8.46 sec. Therefore, in one second the number of vibrations will be as follows.
= 0.377 vibrations
Hence, frequency (f) = 0.38 Hz
Now, formula to calculate the speed is as follows.
v =
or,
=
= 1.57 cm
Thus, we can conclude that the wavelength is 1.57 cm.
Answer:
B
Explanation:
Sunlight comes in the form of light energy. Upon striking the solar panels, it converts the light energy into electrical energy so as to run throughout the circuits. Then since it's used to power light, the electrical energy will be converted back into light energy
The atmosphere is made up of layers which vary in temperature and other characteristics.
<h3>Layers of the atmosphere</h3>
The atmosphere is divided into several layers. The atmosphere refers to the thin layer of air that lies above the earth crust. The following describes the layers of the atmosphere.
- The troposphere refers to the layer where weather changes largely occur and clouds form.
- The stratosphere has an average temperature of about 270 K (−3°C or 26.6°F). The ozone layer is found in the stratosphere.
- The temperature in he mesosphere is about − 85°C (− 120°F).
- The thermosphere has a temperature of 200° C (360° F). The ionosphere is found within the thermosphere.
