A3.50-g bullet, traveling horizontally with a velocity of magnitude 400 m/s, is fired into a wooden block with mass 0.750 kg , initially at rest on a level surface. the bullet passes through the block and emerges with its speed reduced to 190 m/s. the block slides a distance of 72.0 cm along the surface from its initial position. (a) what is the coefficient of kinetic friction between block and surface? (b) what is the decrease in kinetic energy of the bullet? (c) what is the kinetic energy of the block at the instant after the bullet passes through it?

the journeys of marquette, joliet and la salle a) new france expand.

all three of these explorers explored the midwest and the area around the great lakes, which they subsequently claimed for france.

this was a big portion of territory and expanded new france which before then only consisted of quebec province in northeastern canada

the answer is the first electromagnet (a). this is because it has more coils around the ferromagnetic material. increasing the number of coils increases the surface area in which the metal interacts with the current in the coil. this enables more atoms in the metal to become aligned hence becoming more magnetized.
