Two parallel wires of length 17 m are separated by a distance of a = 0.13 cm, What is the magnetic force on each wire
An ion source is producing 6Li ions, which have mass 9.99 x10-27 kg and charge +e. The ions are accelerated by a potential difference of 30 kV and pass horizontally into the region in which there is a uniform vertical magnetic field of magnitude B..
What is linear acceleration
An ?-particle has a charge of +2e and a mass of 6.64 ? 10-27 kg. It is accelerated from rest through a potential difference that has a value of 1.06 X 106 V, What is the speed of the ?-particle
A hot-air balloon is travelling upwards with a constant speed of 12 m/s. An object fell from the balloon when it was at the height of 1000 m
To stop a car, first you require a certain reaction time to begin braking; then the car slows under the constant braking deceleration. Suppose that the total distance moved by your car during these two phases is 50.6 m when its initial speed is 79..
Two charged bodies exert a force of 0.790N on each other. If they are moved so that they are one-fourth as far apart, what force is exerted.
Two charged dust particles exert a force of 4.30×10-2 N on each other. What would be the force if they are moved so they are only one-sixth as far apart.
A 18 liter tank of helium is at a pressure of 192 kPa at a temperature of 0 C. A.) How many moles of helium are there in the tank? B.) If the volume of the tank expands to twice its initial volume at constant pressure, what is the new temperature?..
An Australian emu is running due east in a straight line at a speed of 17.5 m/s and slows down to a speed of 12.2 m/s in 4.1 s. (a) What is the direction of the bird's acceleration? (b) Assuming that the acceleration remains the same, what is the ..
A particle has an acceleration of 6.19 m/s^2 for 0.350 s . At the end of this time the particle's velocity is 9.26 m/s What was the particle's initial velocity?
