Particles of charge Q1 = +69 µC, Q2 = +51 µC, and Q3 = -80 µC are placed in a line (see figure). The center one is 0.35 m from each of the others. Calculate the net force on each charge due to the other two. (Assume the positive direction is to the right.)
Calculate the vertical component of its velocity by the time it hits the ground
Suppose the amount of heat added to the ice block is doubled. By what factor must the mass of the ice be increased if the system is to have the same final temperature
Consider a fish of average size swimming near the bottom of a lake of depth 46 m. What is the water pressure next to the fish
A soccer player kicks a ball that is on the ground down the field. The balls initial velocity is 10 m/s, 30 degrees above the horizontal. How long does is take for the ball to land down the field
A gun shoots bullets that leave the muzzle with a speed of 205m/s. If a bullet is to hit a target 151m away at the level of the muzzle, the gun must be aimed at a point above target.
Besides the gravitational force, a 3.40-kg object is subjected to one other constant force. The object starts from rest and in 1.20 s experiences a displacement of (5.50 - 3.30) m, where the direction of is the upward vertical direction. find the ..
