A train is traveling at 10m/s comes to a complete stop in 40 sec. how far did the train go during the deceleration

Space vehicles traveling through earth's radiation belts can intercept a significant number of electrons. the resulting charge buildup can damage electronic components and disrupt operations. suppose a spherical metallic satellite 1.3 m in diameter accumulates 3.0 µc of charge in one orbital revolution. (a) find the resulting surface charge density. (b) calculate the magnitude of the electric field just outside the surface of the satellite, due to the surface charge.

Curious carl calculated the density of a cube to be 4.50 g/cm3. what is the density of the cube in g/l?

What is a carrier wave and how does it affect what you hear on the radio
