A point particle that has a charge of 18.5 µC is located at x = 0, y = 0 and a point particle that has a charge q is located at x = 14.8 cm, y = 0. The electric force on a point particle that has a charge of 7.4 µC at x = 29.6 cm, y = 0 is -(19.7) N ihatbold. Determine the charge q.
A toy spacecraft is launched directly upward. When toy reaches its highest point, a spring is released and the toy splits into two parts with masses of .c2 kg and .08 kg.
how to calculate the average velocity between to minutes. Estimate how for you can throw a ball if you throw it in the following situations.
A broad beam of light of wavelength 485nm is incident at 90° on a thin, wedge-shaped film with index of refraction 1.50. An observer intercepting the light transmitted by the film sees 17 bright and 16 dark fringes along the length of the film. By..
find the vertical component of a baseball's velocity if the ball is thrown at a 28m/sec at an angle of 37 degrees with the horizontal.
a 500 g ball swings in a vertical circle at the end of a 1.5-m-long string. When the ball is at the bottom of the circle the tension in the string is 15 N. What is the speed of the ball at that point?
An airplane is flying in a horizontal circle at a speed of 100 m/s. The 80.0-kg pilot does not want her radial acceleration to exceed 7g. (a) What is the least radius of the circular path? (b) At this radius, what is the force causing the centripe..
If the charge of the point charge in the figure were -2Q (instead of +Q), by what factor would the magnitude of the force on the point charge due to the dipole change.
A train is travelling up a 4.0 incline at the speed of 3.25 when the last car breaks free and begins to coast without friction. How long does it take for the last car to come to rest momentarily.
Sit on a rotating chair. Slowly twist your body in one direction and after that rapidly twist it in the other. What is going to happen? Is angular momentum conserved and if not why.
What value does this give for the speed of sound in air. What is the speed of the ball at that point.
