In 1911, Ernest Rutherford discovered the nucleus of the atom by observing the scattering of helium nuclei from gold nuclei. If a helium nucleus with a mass of 6.68 10-27 kg, a charge of +2e, and an initial velocity of 1.98 107 m/s is projected head-on toward a gold nucleus with a charge of +79e, how close will the helium atom come to the gold nucleus before it stops and turns around? (Assume the gold nucleus is held in place by other gold atoms and does not move.)
A stretched rubber band has the length of 0.04 m and a fundamental frequency of 462 Hz. What is the speed at which waves travel on the rubber band.
A 0.144 kg baseball is moving towards home plate with a speed of 43.0 m/s when it is bunted. The bat exerts an average force of 6.50 Ã? 103 N on the ball for 1.30 ms, What is the final speed of the ball
Having taken a nap under a tree only 20 m from the finish line, Rabbit wakes up to find Turtle 19.5 m beyond him, grinding along at 1/4 m/s. If the bewildered hare can accelerate at 8 m/s2 up to his top speed of 17 m/s (38 mi/h) and sustain that s..
