hi, this is my question:
In a balloon it was noticed the the pressure, in atmospheres was inversely proportional to the square root of the height, in metres. When the balloon was at a height of 25m, the pressure was 1.44atm.
would K= 7.2?
thanks do u know what k would be in this:
the amount of waste which a firm produces, measured in tonnes per hour, is inversely proportional to the square root of the size of the filter beds, measured in metres squared. At the moment, the firm produces 1.25 tonnes per hour of waste, with filter beds of size 0.16 metres squared.
