Acoaxial cable consists of inner and outer conductors having radii, a and b respectively. they also have charge per unit length of + and respectively. both conductors are thin shells. for this arrangement calculate (using gauss' theorem or otherwise): (a) the electric field at a distance r from the centre of the cable. (b) the potential difference between the conductors. (c) the capacitance of the cable per unit length. (d) the field outside the cable. (e) what is the amount of energy stored per unit length in this configuration, as a function of both and v?

false

the design of a ski jumping suit involves a trade-off between giving the skiers lift to get higher jumps and ensuring the skier does not face a lot of drag before the jump itself. an expansive suit may to lift the skier higher, but at the same time, it will also increase the air resistance. higher air resistance as the skier goes down the slope limits the speed of the jump. a big suit also increases the risk of losing balance or control, especially if there's a strong gust of wind. while technologically enhanced suits a lot, clothing is not the only factor in a ski jumper’s success. gathering speed while skiing down the slope, ensuring good speed on the ramp, and maintaining good body posture and form in the air all contribute to a ski jumper's success.
