An electron is accelerated horizontally from rest in a television picture tube by a potential difference of 5500V. It then passes between two horizontal plates 6.5cm long and 1.3 cm apart that have a potential difference of 250V. At what angle will the electron be traveling after it passes between the plates?
A) Assuming that the Styrofoam absorbs a negligibly small amount of heat and that no heat was lost to the surroundings, what is the specific heat of the metal? B) Which is more useful for storing heat, this metal or an equal weight of water? defin..

Physics: Standing Waves, Second Harmonic, Two pieces of steel wire with identical cross-sections have lengths of L and 2L. Each of the wires is fixed at both ends and stretched so that the tension in the longer wire is three times greater than tha..
Consider a too-small space station that consists of a 2.7m radius rotating sphere. A man standing inside is 1.9m tall and his feet are at 1g. What is the acceleration of his head.
If a person radiates about 65.00 W of power at room temperature, how long does it take for a person to radiate away the energy acquired by consuming a 230 Calorie donut.
A body of mass 200 g is acted upon by a force of 20 n. Find the acceleration of the body. If the body above is having a volume of 1000 cm3 estimate its density in kg/m2.
A string is wrapped around the disk of mass m = 1.8 kg and radius R = 0.11 m. Starting from rest, you pull the string with a constant force F = 8 N along the nearly frictionless surface. At an instant when the center of the disk has moved a distan..
