Acylindrical shell of radius 7.00 cm and length 2.55 m has its charge uniformly distributed on its curved surface. the magnitude of the electric field at a point 17.2 cm radially outward from its axis (measured from the midpoint of the shell) is 36.0 kn/c. (a) find the net charge on the shell.
nc (b) find the electric field at a point 4.00 cm from the axis, measured radially outward from the midpoint of the shell.
kn/c

Who was the first scientist to measure speed as distance over time?

Because air contracts as it cools, the air pressure inside a freezer is typically lower than on the outside. why do ice cubes inside a freezer tend to shrink over time? a. the ice dissolves oxygen from the air, forming a denser crystalline matrix.b. the ice reacts chemically with carbon dioxide in the air, forming gaseous carbon compounds.c. the ice melts, and then the liquid freezes as ice crystals on the bottom of the freezer.d. the ice sublimes, and then the water vapor deposits as ice crystals on the sides of the freezer.

In a classical model of the hydrogen atom, the electron moves around the proton in a circular orbit of radius 0.053 nm. what is the electron's orbital frequency? what is the effective current of the electron?
