An air tank is filled with 0.150m ^ 3 of helium gas, pressurised at 15 200 kPa. We wish to use this air tank to fill balloons, each of which will occupy a volume of 0.113m ^ 3 . How many such balloons can be filled with the helium from the tank, if each balloon must be pressurised to 101 kPa?

The magnitude of the poynting vector of a planar electromagnetic wave has an average value of 0.939 w/m2 . the wave is incident upon a rectangular area, 1.5 m by 2.0 m, at right angles. how much total electromagnetic energy falls on the area during 1.0 minute

Calculate the amount of heat produced when 18000 coulombs of charge is transferred in one hour through a potential difference of 50v

A3030 cmcm wrench is used to loosen a bolt with a force applied 0.30.3 mm from the bolt. it takes 6060 nn to loosen the bolt when the force is applied perpendicular to the wrench. how much force would it take if the force was applied at a 3030 degree angle from perpendicular? a 3030 cmcm wrench is used to loosen a bolt with a force applied 0.30.3 mm from the bolt. it takes 6060 nn to loosen the bolt when the force is applied perpendicular to the wrench. how much force would it take if the force was applied at a 3030 degree angle from perpendicular?
