Two point charges q1 and q2 are held in place 4.50 cm apart. Another point charge Q = -1.75 mC, of mass 5.00 g, is initially located 3.00 cm from both of these charges and released from rest. You observe that the initial acceleration of Q is 324 m>s2 upward, parallel to the line connecting the two point charges. Find q1 and q2.

Tafari worked one summer on a ship that set weather buoys in the ocean. he watched how one of the buoys moved in the water. describe which parts of the wave would cause the buoy to bob up and down. which wave property determined how fast the buoys bobbed in the water? he observed that when the wind blew harder, the ocean waves were larger, and the buoys moved away from the ship. what effect, if any, did the waves have on how far the buoys moved? explain your answer.

How does the entropy of steam compare to the entropy of ice?

Alarge cruise ship of mass 7.00 ✕ 107 kg has a speed of 11.6 m/s at some instant. (a) what is the ship's kinetic energy at this time? (b) how much work is required to stop it? (give the work done on the ship. include the sign of the value in your answer.) (c) what is the magnitude of the constant force required to stop it as it undergoes a displacement of 3.00 km?
