Answer:
Radius, r = 0.00523 meters
Explanation:
It is given that,
Magnetic field, 
Current in the toroid, I = 9.6 A
Number of turns, N = 6
We need to find the radius of the toroid. The magnetic field at the center of the toroid is given by :

r = 0.00523 m
or

So, the radius of the toroid is 0.00523 meters. Hence, this is the required solution.
Answer:
3.5 seconds of flight time; 13.9 m from the base of the cliff
Explanation:
<u>Acceleration</u> is the rate at which <u>velocity</u> changes.
25 x 10^-5
= 0.00025
25 cm
= 0.00025 km
