Current Attempt in Progress Earth's atmosphere is constantly bombarded by cosmic ray protons that originate somewhere in space. If the protons all passed through the atmosphere, each square meter of Earth's surface would intercept protons at the average rate of 1900 protons per second. What would be the electric current in amperes intercepted by 2 40 % 107 km? area on the planet?

Particle 1 of charge 40.1 UC is located at x - -31.1 cm; particle 2 of charge Q is located at x - 29.8 cm. Particle 3 of charge magnitude 30.0 JC is released from rest on the y axis at y - 31.1 cm. What is the value of Q if the initial acceleration of particle 3 is in the positive direction of (a) the x axis and (b) the y axis?

Suppose, however, that these magnitudes differ from each other by 000082 %, With what force would two copper coins, placed (.82 m apart, repel each other? Assume that each coin contains 2.5 = 103 copper atoms. (Hint: A neutral copper atom contains 2% protons and 29 electrons.) Mumber n Units v eTextbook and Media Save for Later Attempts: 0 of 3 used
