Stopped at the end of the tracks by a spg-damper system, as shown in fig. 1
Answer:
The statement that the net magnetic field at the center of this square is zero is false.
The net magnetic field inside a conductor must be zero - This is a true statement
Explanation:
The net magnetic field at the center of this square is not equal to zero.
The net magnetic field at the center of this square is given by the equation below:
B = 2√2μ₀I/πₐ
Where a = the side of the loop, and I is the current.
Thus, the statement that the net magnetic field at the center of this square is zero is false.
The net magnetic field inside a conductor must be zero - This is a true statement because the total charge on the conductor must be equal to zero.
Answer:
starting position: 3 m
velocity: 3 m/s
Explanation:
at t=0 position= 3 m
velocity: (delta)position/(delta)time
(delta=change in)
velocity= (15-3)/(4-0)
velocity= 12/4
velocity= 3 m/s
The answer to question one would be Ethier A or D and the answer to question number 2 is B friction the answer to question number 3 is B kinetic energy
<span>The rate at which energy is transferred is called "power."</span>
