The electric potential inside a charged spherical conductor of radius R is given by V = keQ/R, and potential outside is given by V = keQ/r. Using Er = -dV/dr, derive the electric field (a) inside and (b) outside this charge distribution.

Critical mass is the of material required to produce a chain reaction. a.) minimum amount b.) atomic mass c.) precise amount d.) maximum amount

If y gets smaller as x gets bigger and y have an relationship?

The california mussel (mytilus californianus) attaches itself to a rock or other solid surface with a bundle of filaments known as the byssus. imagine that 15.0 j of work is done to stretch the distal end of the byssus. it releases 10.8 j of thermal energy as it relaxes. what is the resilience of the distal end of the byssus?
