Professor goetz took a heavy marine 100 foot, 0.75 lb per foot rope and through it through his office window. one end of the rope touches the ground. professor goetz missed his lunch and can only exert 300kcal (the equivalent of a healthy sandwich). he realized he does not know if he has enough energy to lift the rope back into his office. a) how much energy in kcalories is needed to lift the rope half way from the ground. b) calculate whether he is capable of lifting the rope all the way up. c) a person who eat a candy gains extra 50kcal. if this energy is used to lift the rope, how many feet will it be lifted from the ground.

An isolated conducting spherical shell carries a positive charge. part a which statement (or statements) about the electric field and the electric potential inside and outside the spherical shell is correct? which statement (or statements) about the electric field and the electric potential inside and outside the spherical shell is correct? electric potential inside the shell is constant and outside the shell is changing as 1/r2 both the electric potential and the electric field does change with r inside and outside the spherical shell electric potential inside and outside the shell is constant, but not zero electric potential inside the shell is constant and outside the shell is equal to zero electric field inside and outside the shell is constant (does not change with the position r), but is not equal to zero electric field inside and outside the shell is changing as 1/r (where r is the distance from the center of the sphere) electric field inside is equal to zero and outside the shell is constant, but not zero electric potential inside the shell is constant and outside the shell is changing as 1/r electric field inside and outside the shell is changing as 1/r2 electric field inside is equal to zero and outside the shell is changing as 1/r2 electric field inside and outside the shell is zero electric field inside is constant and outside the shell is changing as 1/r
