Ahollow sphere made of brass has a weight of 3 n and dips into water (density ph20 997 ) with half of its volume. a) what is the diameter d of the sphere and the thickness x of the brass wall, if brass b) what is the work w needed to pull the sphere out of the water? hint: neglect the surface tension. take the formula for the cap of a sphere from a book or another good source.

explanation:

because if the tool that you are using is not balanced it there would be false mass.

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.
