In a spherical metal shell of radius r, an electron is shot from the center directly toward a tiny hole in the shell, through which it escapes. the shell is negatively charged with a surface charge density (charge per unit area) of 6.40 × 10^-13 c/m^2. what is the magnitude of the electron's acceleration when it reaches radial distances (a) r = 0.690 r and (b) 2.00r?

layers of the earth affect the waves and these effects are seen on instruiments such as seimometers

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.

c because the news are a source of information of things that happen on the daily and shows evidence about that particular topic

force tends to be low and long diustance masses are high
