Her magnitude of deceleration on the ice would be 15.126m/s
-- heat the magnet red-hot in a flame
-- drop it on the floor several times, or beat it with a hammer
-- place it in a strong, rapidly alternating external magnetic field
Answer:
The bones aren't as strong as a younger person, because an older person, ages due to time and it also depend on what they do in their past.
Does this help? ^-^"
The answer is 36 kilometers per hour, or 10 meters per second.
Answer:
Number of turns per unit length will be 
Explanation:
We have given that strength of the magnetic field produced by the solenoid B = 7 T
Current in the solenoid i = 200 A
Let the number of turns per unit length is n
Magnetic field due to solenoid is given as 
here 
is permeability of free space n is number of turns per unit length and i is current
So
