A 50-turn circular wire loop has a radius 3 cm and is located in a uniform magnetic field. The magnetic field lines are perpendicular to the plane of the circular loop. Suppose that the magnetic field is varied so that BBB increases from 0.1 T to 0.35 T in 1.95 ms. Part A Find the average induced emf in the coil (including sign of the emf). View Available Hint(s)

Arunner is jogging at a steady 3.6 km/hr. when the runner is 2.9 km from the finish line, a bird begins flying from the runner to the finish line at 14.4 km/hr (4 times as fast as the runner). when the bird reaches the finish line, it turns around and flies back to the runner. even though the bird is a dodo, we will assume that it occupies only one point in space, i.e., a zero-length bird. how far does the bird travel? (b) after this first encounter, the bird then turns around and flies from the runner back to the finish line, turns around again and flies back to the runner. the bird repeats the back and forth trips until the runner reaches the finish line. how far does the bird travel from the beginning? (i.e. include the distance traveled to the first encounter)

A10nc charge sits at a point in space where the magnitude of the electric field is 1500 n/c. what will the magnitude of the field be if the 10 nc charge is replaced by a 20 nc charge? assume the system is big enough to consider the charges as small test charges.

Mechanical energy is when the amount of kinetic and potential energies added together remains the same. conserved created lost
