Electrons in the picture tube of an old-style television travel at 1.25 × 108 m/s. At this speed, how much time does it take the electrons to travel 11.5 inches? State your answer in microseconds (µs).

DCM¹ Consider a DCM from ê to ê' that equals to the following: 0.6124 -0.2803 0.7392 0.7071 0.6124 -0.3536 0.7392 X 0.5732 Compute x, give the result with 4 decimals and verify that the properties of the DCM are satisfied.

In this problem we will observe how the momentum of an electron changes as its velocity approaches the speed of light. The mass of an electron is 9.109 × 10-31 kg.   Part (a)  First, what is the momentum of an electron which is moving at the speed of a car on a highway, say 29 m/s, in kilogram meters per second?

Part C: Sig fig Recognition: Determine the number of sig figs for the measured values listed below. Measurement 8m 1023 kg 0.0023 A 100.0 V 50 s 2.00000 F 101 kV 22.600 x 10-² J Number of Sig Figs 002

If velocity =−12i + 21.5j m/s, how fast is it moving? (Express the answer to two significant figures).

hello, I have this physics book and I want to ask how to do this problem. Hopefully you guys can reply fast because I have a test coming up soon and I cannot grasp this question.

the average density of an atom is approximately 103 kg/m3. The nucleus of an atom has a radius about 10-5 times that of the entire atom, and contains nearly all the mass of the atom.  What is the approximate density, in kilograms per cubic meter, of a nucleus?
