Answer:
Explanation:
Resistivity is given by where A is cross-sectional area, R is resistance, L is the length and is the reistivity. Substituting 0.0625 for R, 3.14 × 10-6 for A and 3.5 m for L then the resistivity is equivalent to

➷ When electrons are lost, a positive ion is formed. This is because there are now more protons than electrons causing the overall charge to be positive.
When electrons are gained, a negative ion is formed. This is because there are now more electrons than protons causing the overall charge to be negative.

Air moving across your skin promotes evaporation of the moisture on
your skin, and evaporation always carries heat energy away with it.
That's the whole purpose of sweating ... Your insides say to each other:
"We're burning up in here and we've got to get some relief ! Pump that
moisture out to the skin where it can evaporate and carry away some of
this heat energy that's building up in here!"
That's why you feel even hotter on a very humid day ... because you're
not able to evaporate as much moisture into air that's already very humid,
even if it's moving.
Well,
We know that microwaves and infrared waves (C and D) have longer wavelengths than visible light.
We know that UV light will give you a sunburn if you get too much of it.
Therefore, UV light has more energy, and thus a shorter wavelength than visible light.
Option B is the correct answer.
Higher frequencies are present in more dramatic events and have thus been the first to be noticed, but the frequencies of ordinary gravitational waves are relatively low and considerably more difficult to detect.
A gamma-ray burst (GRB), which was discovered by the orbiting Fermi gamma-ray burst monitor on 2017 August 17 at 12:41:06 UTC, triggered an automatic notice throughout the world in addition to a merger of black holes. Six minutes later, a gravitational-wave observatory in Hanford, Washington, detected a gravitational-wave candidate that occurred 2 seconds before the gamma-ray explosion.
This collection of data supports the merger of two neutron stars, as shown by a multi-messenger transient event that was detected by gravitational waves as well as electromagnetic (gamma-ray burst, optical, and infrared) spectrum observations.
