Answer:
5. Solenoid B’s magnetic field is 2.7 times greater than solenoid A's magnetic field.
Explanation:
The magnetic field produced by a solenoid depends on number of coils, the length of the solenoid and the amount of current flowing through the coil.
Current in solenoid B is 2 times greater than the current in solenoid A.
Number of coils in B is 4 times greater than coils in A
Length of the solenoid B is 3 times greater than solenoid A
Thus, solenoid B's magnetic field is 2.7 times greater than magnetic field of solenoid A.
122.65 or 122 kilometers per hour
This is an example of Newton's first law of motion:
An object at rest will remain at rest unless an unbalanced force acts upon it. Similarly, a moving object will remain moving in a straight line at constant velocity unless an unbalanced force acts upon it.
The answer is C.
Acceleration is the way the motion is changing.
