Answer:
In both cases, energy will move from an area of higher temperature to an area of lower temperature. So, the energy from room-temperature air will move into the cold water, which warms the water.
Explanation:
this is the answer okkkkkkkkkkkkkkkk
a).β=0.53 T
a).β=0.40 T
The magnetic field at distance 'r' from the center of toroid is given by:
a).
b).
The distance is the radius add the cross section so:
13.23J
PE = m*g*h
PE = (3 kg ) * (9.8 m/s/s) * (0.45 m)
1500 north
L=F•d=>d=L/F=40,000/20=2,000 m
Be pushed away from each other.
