A proton moving in the positive x direction with a speed of 9.4 105 m/s experiences zero magnetic force. When it moves in the positive y direction it experiences a force of 2.5 10-13 N that points in the positive z direction. Determine the magnitude and direction of the magnetic field.

The law of the conservation of momentum says that the total momentum of any closed and isolated system cannot

Antireflective coatings on solar cells are often made by applying a thin film of silicon nitride (sinx), which has an index of refractive of 1.2, on the top of the silicon solar cell, which has a refractive index of about 3.5. however, the sun emits radiation of various wavelengths which the solar cell absorbs, and the antireflective coating can only absolutely minimize the reflection of one of these wavelengths. the coating thickness is chosen to reduce the reflection of green/yellow light (e = 2.2 ev), which is the most intense color in the solar spectrum (shown below). which of the following coatings would minimize reflection of green/yellow light? the answer is 820 nm how? what is the angular width of the central maximum of an electron traveling at 2 x 108 m/s going through a single slit of width 1 mm.

You are waiting in line to use the diving board at your local pool.while watching people dive into the pool from the board,you realize that using a diving board to spring into the air before a dive is good example newton's third law of motion.explain how a diving board illustrated newton's law of motion
