As part of the Apollo space missions to the Moon, astronauts were required to measure the mass of collected lunar rock samples using a spring balance. The spring balance was calibrated to measure mass in the non-SI unit of the pound. The gravitational field strength on the Moon is 1/6th of that on Earth
. (a) A sample of lunar rock was observed to have a mass of 35 pounds. Calculate the weight of the sample on the Moon. 1 pound = 0.45kg(i already know the answer to part A)
(b) The sample measured in part (a) was brought to Earth. Suggest how the measurements could be scaled so that the same spring balance could be used to measure the mass of the sample on Earth.
PLEASE HELP ME WITH PART B. THE MARK SCHEME SAYS "divide by 6" but i have no idea why that is so,in fact i thought we should multiply by 6... i would really appreciate an explanation,thanks.
