Answer:

Decrease
Explanation:
I = Current = 3.7 A
e = Charge of electron = 
n = Conduction electron density in copper = 
= Drift velocity of electrons
r = Radius = 1.23 mm
Current is given by

The drift speed of the electrons is 

From the equation we can see the following

So, if the number of conduction electrons per atom is higher than that of copper the drift velocity will decrease.

Answer:
They can be rank in the following way:
- A radio signal from an AM radio station at 680 kHz on the dial
- Radiation from an FM radio station at 93.1 MHz on the dial
- The red light of a light-emitting diode, such as in a calculator
- The yellow light from sodium vapor streetlights
- The gamma rays produced by a radioactive nuclide used in medical
Explanation:
The electromagnetic spectrum is the distribution of radiation due to the different frequencies at which it radiates and its different intensities, that radiation is formed by electromagnetic waves, which are transverse waves formed by an electric field and a magnetic field perpendicular to it.
Radiation is distributed along that electromagnetic spectrum according to the wavelength or frequency.
Highest frequencies
X-rays
Ultraviolet rays
Visible region
Lower frequencies
Infrared
Microwave
Radio waves
Radio waves and the visible region (yellow light, red light) are part of the electromagnetic spectrum, any radiation of that electromagnetic spectrum has a speed of 3.00x10^{8}m/s in vacuum.
However, the following equation relates the velocity, the frequency, and the wavelength:
(1)
(2)
It can be see in equation 2 that the frequency and the wavelength are inversely proportional (when the frequency increases the wavelength decreases).
Therefore, for what was already discussed, they can be rank in the next way:
- A radio signal from an AM radio station at 680 kHz on the dial
- Radiation from an FM radio station at 93.1 MHz on the dial
- The red light of a light-emitting diode, such as in a calculator
- The yellow light from sodium vapor streetlights
- The gamma rays produced by a radioactive nuclide used in medical
Summary:
In the case of the radio waves can be used:

First of all, don't forget that the sun is 400 times farther from us than the moon is. That fact alone tells us that anything on the earth is attracted to each kilogram of the moon with a force that's 160,000 times stronger than the force that attracts it to each kilogram of the Sun.
But more to your point ... The tides ARE greatly influenced by the sun. That's why tides are considerably higher at New Moon, when the sun and moon are both pulling in the same direction.
They are relatively straight or as straight as they are going to get during a given month that is when a full moon occurs.
