<u>Answer:</u>
Chipmunk's average acceleration during the 2.07 s time interval = 0.1256
<u>Explanation:</u>
We have equation of motion, v = u + at, where v is the final velocity, u is the initial velocity, a is the acceleration and t is the time taken.
In this case we need to find acceleration value, we have initial velocity = 1.47 m/s, final velocity = 1.73 m/s and time taken = 2.07 seconds.
Substituting
1.73 = 1.47 + a * 2.07
a = 0.1256
Chipmunk's average acceleration during the 2.07 s time interval = 0.1256
The magnetic field at the center of the 2nd loop is half the magnetic field at the center of the 1st loop.
Explanation:
The magnetic field strength at the center of a current-carrying circular loop is
where
is the vacuum permeability
I is the current
R is the radius of the loop
For the first circular loop, we have
The second loop has
(same current)
(twice the radius)
So, the magnetic field at the centre of the second loop is
So, the magnetic field at the center of the 2nd loop is half the magnetic field at the center of the 1st loop.
