Answer:
The electric field inside the wire will remain the same or constant, while the drift velocity will by a factor of four.
Explanation:
Electron mobility, μ = 
where
= Drift velocity
E = Electric field
Given that the electric field strength = 1.48 V/m,
Therefore since the electric potential depends on the length of the wire and the attached potential difference, then when the electron mobility is increased 4 times the Electric field E will be the same but the drift velocity will increase four times. That is
4·μ = 
Answer:
I matched the answers you requested above
Answer:
his results in the final angle after the collision of 37.2 degrees basically what we did there is turn the vector into a right triangle. We use sohcahtoa to solve for the angle. Being.
Explanation:
During a total lunar eclipse, Earth completely blocks direct sunlight from reaching the Moon. The only light reflected from the lunar surface has been refracted by Earth's atmosphere. ... Due to this reddish color, a totally eclipsed Moon is sometimes called a blood moon.
Answer:
9.0 m/s
Explanation:
The problem can be solved by using the following suvat equation:
where
v is the final velocity
u is the initial velocity
is the acceleration of gravity
t is the time
When the ball reaches the maximum height, the velocity becomes zero. If we consider this as initial point of the motion, we can write
u = 0
The time it takes for the ball to go down from the maximum heigth to the ground is half the total time, so
And solving the formula for v, we find the final velocity:
So, the final speed is 9.0 m/s.
