How would you calculate how many electrons are transferred with each rotation by the Van de Graff generator? As is known, the Van De Graff generator is spherical and the one I used in particular had a circular summit that stuck out from the very top. I put a packing peanut on top of it, and it only took one rotation--or crank--to knock the material off from the machine and onto the ground. mass of the peanut=.001 kg, distance from the machine to the peanut=.0005m.
NASA sends a satellite to another planet by placing the satellite in a Keplerian orbit (around the sun) such that the perihelion is at the radius of the Earth's orbit (1 AU) and the aphelion is at the radius of the planet's orbit. Most of the trip is..
Illustrate a new gravitational potential energy
The K-shell ionization energy of copper is 8979 eV. The L-shell ionization energy is 951 eV. Determine the wavelength of the Kα emission line of copper. What should be the minimum voltage be on an x-ray tube with a copper target in order to see the K..
If a 2.00{rm kg} mass is now attached to the end of the spring, where will the end of the spring line up with the ruler marks?
Starting with the three particle system, find the change in electric potential energy if the alpha particle is allowed to escape to infinity while the two protons remain fixed in place. (Throughout, neglect any radiation effects.)
A proton is placed in an electric field of intensity 700 N/C. What is magnitude and direction (towards or away from the field) of the acceleration of this proton because of this field? The charge on a proton is +1.6 x 10-19 C and the mass of a prot..
A 2.30-? F capacitor is fully charged by being connected to a 6.0-V battery. The fully charged capacitor is then connected to a 0.250-H inductor.
A cannonball shot with the initial velocity of 129 m/s at an angle of 36° follows a parabolic path and hits a balloon at the top of its trajectory. Neglect air resistance, how fast is the cannonball going as it hits the balloon.
The magnetic field has been measured to be horizontal everywhere along a rectangular path x = 22 cm long and y = 5 cm high. Along the bottom the average magnetic field B1 = 1.3 10-4 tesla, along the sides an average magnetic field B2 = 1.0 10-4 te..
An opera singer in a convertible sings a note at 419 Hz as cruising down the highway at 81.0 km/hr. What is the frequency (in Hz) heard by a person standing beside road in front of the car? suppose that the speed of sound is 343 m/s.
What is the temperature of the outside air. What are the components of the displacement vector from camp to summit? What is its magnitude? select the x axis east, y axis north, and z axis up.
A flight attendant pulls her 72-N flight bag a distance of 265-m along a level airport floor at a constant velocity. The force she exerts is 44-N at an angle of 57° above the horizontal.
