A13 g bullet traveling 213 m/s penetrates a 2.0 kg block of wood and emerges cleanly at 152m/s. if the block is stationary on a frictionless surface when hit, how fast does it move after the bullet emerges?

Individuals who live below the poverty line get seriously ill more often than those who do not what could be the hidden variable in this situation?

Two 1.20-m nonconducting wires meet at a right angle. one segment carries + 2.50 µc of charge distributed uniformly along its length, and the other carries - 2.50 µc distributed uniformly along it, as shown in fig. 21.50. ( a. find the magnitude and direction of the electric field these wires produce at point p, which is 60.0 cm from each wire. ( b. if an electron is released at p, what are the magnitude and direction of the net force that these wires exert on it?

A2.0 μf capacitor and a 4.0 μf capacitor are connected in series across a 0.827-kv potential. the charged capacitors are then disconnected from the source and connected to each other with terminals of like sign together. find the voltage across each capacitor.
