An electron with kinetic energy of 6.0 x 10-16 J is moving to the right along the axis of a cathode-ray tube. There is an electric field vector = (2.0 x 104 N/C) j in the region between the deflection plates. Everywhere else, vector = 0. Feedback: 2) At what angle is the electron moving with respect to the axis? (Positive angle measured counterclockwise with respect to the axis) 3) At what distance from the axis will the electron strike the fluorescent screen?
Assume a uniform mass distribution before and after. Icm for a solid sphere of uniform density is 2/5 mr2.
what is the final position of the man. What is the magnitude of the electric field (in N/C) at the point (-2.0 m, 3.0 m).
Water runs out of the horizontal drainpipe at the rate of 120 liters per minute. It falls 3.20 m to the ground. Assume the water doesn't splash up, what average force does it exert on the ground? (1 liter = 1 kg.)
Two parallel plates are charged to a voltage of 50V. If the separation between the plates is 0.05m, what is the electric field between them?
A 220 g block on a 50 cm long string swings in a circle on a horizontal, frictionless table at 95.0 rpm. what is the tension on the string.
Differentiate between the following three types of plain carbon steels.
Estimate, from these data, the effective distance between the atoms.
To which, according to the rotational analog of Newton's second law, is the angular acceleration experienced by an object directly proportional?
An insulated Thermos contains 110cm3 of hot coffee at 90 °C. You put a 12g ice cube at its melting point to cool the coffee. By how many degrees has the coffee cooled once the ice has melted and equilibrium is reached? Care for the coffee as thoug..
A bat flying in a cave emits a sound and receives its echo 0.37s later. How far away is the cave wall? (Hint: The sound has to travel to the wall and then back again. Use 340 m/s for the speed of sound.)
The escape speed from the Earth is 1.12 × 10^4 m/s, so a gas molecule traveling away from Earth near the outer boundary of the Earth's atmosphere would, at this speed, be able to escape from Earth's gravitational field.
River Pascal with a volume flow rate of 3.3×10^5 joins with River Archimedes, that carries 1.09×106 , to form the Bernoulli River. The Bernoulli River is 120 wide and 20 deep.
