Aspherical shell, of radius r, carrying a uniform surface charge σ, is set spinning at angular velocity ω (a) find the vector potential it produces at point r (both r r and r2 r). [20 points) (b) find the magnetic field inside this spherical shell. [10 points] (c) find the magnetic field outside this spherical shell.

answer: 802.3 kilo joules of energy represents 191.75 kilo calorie of energy.

explanation:

energy released during combustion of one mole methane = 802.3 kilo joules

if 1 kilo joule = 0.239006   kilo calorie

then ,802.3 kilo joule will be = 802.30.239006 kilo calorie

802.3 kilo joule = 191.75 kilo calorie

hence, the energy in kilo calorie is 191.75 kilo calorie.

a longitudinal wave moves energy that is to the direction of the wave’s movement. - true

the answer is neither ball has a charge.

because if they were both positively charged, they will repel each other.

if they were positively and negatively charged, they will seek.
