As the plates continues to grind against each other, what geologic events could take place

Enise is riding her bike and falls to the ground. During the collision, she hits both grass and cement. Which best explains why Denise had fewer injuries to the area of her body that hit the grass?

A grinding wheel, initially at rest, is rotated with constant angular acceleration of 7.36 rad/s 2 for 5.73 s. The wheel is then brought to rest with uniform deceleration in 8.37 rev. Find the angular acceleration required to bring the wheel to rest.

When is the force on a current-carrying wire in a magnetic field at its strongest? -when the current is at a 0-degree angle to the field -when the current is at a 30-degree angle to the field -when the current is at a 45-degree angle to the field
