Answer:
The number of turns in the second coil is more than the coil 1.
Explanation:
The magnetic field lines are the imaginary path on which an isolated north pole moves if it is free to do so.
The tangent at any point to the magnetic field line, gives the direction of magnetic field at that point.
More be the crowd ness of magnetic field lines more is the strength of magnetic field.
Here the crowd ness of magnetic field lines is more in figure 2 , so the magnetic filed in figure 2 is more than 1. It shows that the number of turns in the second coil is more than the 1 and also the current in the coil 2 is more than 1 .
The PWC must be slowed to "slow, no wake" speed when the operator is within 50 feet of the swimmer.
"Slow, no wake" speed means the boat is at its slowest needed to keep steerage, reducing or getting rid of waves that comes out as white water trailing the boat.
Answer:
520000 or 520000 pa
Force = 520N
Area of contact = 0.001
Pressure: 520000 or 520000
Answer:
43 revolutions.
Explanation:
The time it takes for the car to stop is
The distance it travels in that time is
The number of revolutions that the tires make is then
<em>The last calculation just asks the question "how many tire circumferences fit into d=113 meters?"</em>
