In the Bohr theory of the hydrogen atom, an electron moves with constant speed in a circular orbit about a proton, where the radius of the orbit is 0.53 x 10-10 m.
a) Determine the electrostatic force (magnitude and direction) exerted by the proton on the electron.
b) Determine the electrostatic force (magnitude and direction) exerted by the electron on the proton.
c) If this force causes the centripetal acceleration of the electron, what is the speed of the electron? (The mass of the electron is m=9.11*10^-31 kg.)
A spring with spring constant k = 210N/m is at first compressed x = 1.90 cm. It is now allowed to relax back to its equilibrium length and then it is stretched an additional 2.30 cm. How much work is completed by the spring during this process.
An airplane is flying with a velocity of 90 m/s at an angle of 25 above the horizontal. When the plane is a distance 126 straight above a dog that is standing on level ground, a suitcase drops out of the luggage compartment.
a transformer has N^1 =350 turns and N^2 =2000 turns. If the input voltage is 170V, what voltage is developed across the secondary coil?
An ocean liner leaves New York City and travels 37.0° north of east for 171 km. How far east and how far north has it disappeared? In other words, what are the magnitudes of the components of the ship's displacement vector in the directions.
A parachutist with a camera, both descending at a speed of 11 m/s, releases that camera at an altitude of 140 m. Explain how long does it take the camera to reach the ground?
A jet plane lands with a speed of 98 m/s and can accelerate at a maximum rate of 5.90 m/s2 as it comes to rest. (a) From the instant the plane touches the runway.
The department actually completed 10,000 hours of production. Illustrate what is the appropriate total budget for the department, assuming it uses flexible budgeting?
You're carrying a 4.0-m-long, 25 poles to a construction site when you choose to stop for a rest. You place one end of the pole on a fence post and hold the other end of the pole 35 from its tip. How much force should you exert to keep pole motionles..
You place one end of the pole on a fence post and hold the other end of the pole 35 from its tip. Explain how much force must you exert to keep the pole motionless in a horizontal position
