The electric dipole moment of a dipole in a 300 n/c electric field is initially perpendicular to the field, but it rotates so it is in the same direction as the field. if the electric dipole moment has magnitude 2.0 x 10- cm, what is the work done by the field? a) w12 x 10-7j b) w-6.0 x 10-7j c) w +6.0 x10-? j d) w +12 x 10-7 j =

During takeoff, the sound intensity level of a jet engine is 170db at a distance of 34 m. what's the sound intensity level at a distance of 1.0 km?

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?

Positrons are spontaneously emitted from the nuclei of
