Consider a coil lying in the plane of the screen and the external magnetic field pointing into the screen. As the external magnetic field decreases, an induced current flows in the coil.
What is the direction of the induced magnetic field caused by this current?

How does convection affect our atmosphere? our layers of earth? our oceans?

Determine the maximum r-value of the polar equation r =3+3 cos 0

Boxing gloves are padded to lessen the force of a blow. (a) calculate the force exerted by a boxing glove on an opponent’s face, if the glove and face compress 7.50 cm during a blow in which the 7.00-kg arm and glove are brought to rest from an initial speed of 10.0 m/s. (b) calculate the force exerted by an identical blow in the gory old days when no gloves were used and the knuckles and face would compress only 2.00 cm. (c) discuss the magnitude of the force with glove on. does it seem high enough to cause damage even though it is lower than the force with no glove?
