Consider two identical electric bulbs of power P and resistance R. You connect them to a battery of voltage V. The first time you connect them in series with each other, and the second time in parallel. How will the illumination of the connection in parallel compare with the connection in series?

a. 1/2 of the illumination of connection in series
b. 2X as much illumination as connection in series
c. 1/4 of the illumination of connection in series
d. The same illumination as connection in series
e. 4X greater illumination as connection in series

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.
