A red laser from the physics lab is marked as producing 632.8-nm light. When light from this laser falls on two closely spaced slits, an interference pattern formed on a wall several meters away has bright red fringes spaced 5.00mm apart near the center of the pattern. When the laser is replaced by a small laser pointer, the fringes are 5.19mm apart. What is the wavelength of light produced by the pointer?
Two identical point charges are fixed distance from one another. If one of their charges was doubled an the other was halved, how would the electric force be affected.
A parallel-plate capacitor has plate area 2.5×10?3m2 and plate spacing 3.0×10?2m, Find the stored charge and energy when this capacitor is connected across a 60V battery
Four charges are placed in a three-dimensional space. The charges have magnitudes 2 nC, -4 nC, 1 nC, and -9 nC. If a Gaussian surface encloses all the charges, what will be the electric flux through that surface?
Blocks with masses of 2.0 , 4.0 , and 6.0 are lined up in a row on a frictionless table. All three are pushed forward by a 57 N force applied to the 2kg block.How much force does the 4 block exert on the 6.0 block.
A car traveling at 21 {rm m/s} runs out of gas while traveling up a 25^circ slope. How far up the hill would it coast before starting to roll back down.
Illustrate what is the magnitude of the apparent weight of a 79 kg astronaut 5100 km from the center of the Earth's Moon in a space vehicle moving at constant velocity?
A spring has a force constant of 323 N/m and an unstretched length of 6 cm. One end is attached to a post that is free to rotate in the center of a smooth table, as shown in the top view below. The other end is attached to a 4-kg disk moving in un..
