a voltmeter of 500-ohm resistance is connected in parallel to an unknown resistance then an ammeter oh negligible resistance is connected to them in series and when the termnals of this circuit are connected to an electric cell the ammeter reading become 0.01 A and the voltmeter reading becomes 3v so the value of the unknown resistance = a)900 b)800 c)750 d) 620

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.
