An approximation for the magnetic field at the edge of a certain C-shaped magnet is Show that this approximation is consistent with Maxwell’s equations in free space.
Find the magnitude and direction of the force on a square loop of current which has sides length b = 10 cm, positioned with its left edge a distance c = 12 cm from the magnet opening, and carrying a current of 2.6 A counterclockwise. Let and a = 30 cm.
If the loop is rotated by an angle 20º about the x axis, how much torque does it experience and it which direction?

Write short note on the following ; collision theory, rotation angle and angular velocity, centripetal acceleration, coriolis force, and newton's law of gravitation.

At very high pressures, gases become and will eventually a) more dense; become hotter b) more dense; change to a liquid or solid c) less dense; combust d) less dense; turn into a liquid

Astone is thrown with a speed v0 and returns to earth, as the drawing shows. ignore friction and air resistance, and consider the initial and final locations of the stone. which one of the following correctly describes the change δpe in the gravitational potential energy and the change δke in the kinetic energy of the stone as it moves from its initial to its final location? options a.δpe = 0 j and δke = 0 j b.δpe is positive and δke is negative c.δpe = 0 j and δke is positive d.δpe is negative and δke is positive e.δpe = 0 j and δke is negative
