Explanation:
Diameter of toroid is 15 cm =0.15 m
So length of the toroid is 
Number of turns of the toriod is given as 555
Current through the toroid is 0.670 A
Magnetic field

Answer:
There are areas in California that use the heat from deep in the Earth to generate electricity.
Explanation:
It comes from the earth itself and we use a lot of things that comes from the earth and deep within it.
Answer:
The final velocity of the ball is 7m/s
Explanation:
M1=8kg, V1 =10m/s
, M2=2kg
, V2=-5m/s
initial momentum before collison
m1v1+m2v2
=8×10 +2×(-5) =80-10 = 70kg m/s
final momentum after collison
=(m1+m2)×v
=(8+2)×v
=10v
According to the law of conversion of momentum
initial momentum =final momentum
70=10v
10v=70
v=70/10
v=7m/s
