Answer:
Yes it is true because static friction help us to make grip between the foot and the ground surface
Explanation:
Yes, as we know that the friction between two surface is of two types
1) Static friction
2) Kinetic friction
When two surface moves relative to each other then the friction force between two surface is kinetic friction and it always opposes the relative motion of two rough surface
While when one surface has tendency to move with respect to its contact surface but if it can not move on it then in this case it is static friction
So relative motion is not possible in this type of friction
So static friction helps to prevent slipping
If it's a small object near another gigantic object, then we usually call that the small object's "weight".
The strength of the electromagnet depends on how many coils you wrap round and how high the voltage is. ... N Increasing the number of coils, which adds more field lines and makes the electromagnet stronger. This is the magnetic field around a piece of wire, compared to a magnetic field on a loop or solenoid it is weak.
