Answer:
2C
Explanation:
The equivalent capacitance of a parallel combination of capacitors is the sum of their capacitance.
So, if the capacitance of each capacitor is half the previous one, we have a geometric series with first term = C and rate = 0.5.
Using the formula for the sum of the infinite terms of a geometric series, we have:
Sum = First term / (1 - rate)
Sum = C / (1 - 0.5)
Sum = C / 0.5 = 2C
So the equivalent capacitance of this parallel connection is 2C.
Answer:
133.33 miles per hour
Explanation:
There are many students who can not get answers step by step and on time
So there are a wats up group where you can get help step by step and well explained.
Infra-red radiation has a slightly longer wavelength than red light ...
the longest wavelength that is visible to the human eye.
Although infrared can't be detected by the eye, we do have other
receptors that CAN detect it. They are some of the nerve endings
in our skin. When infrared radiation hits these, it produces the feeling
of warmth. Infrared radiation carries heat energy.
Answer:
Volume charge density: When the charge density is throughout the volume of a body, then the charge per unit volume is called volume charge density and it is represented by ρ.
∴ρ=
Hence the unit of ρ is Cm
−3
Example: If a charge q is uniformly distributed in the whole volume of a
sphere of radius R, then p =
=3q/4πR-3
