Answer:
we can conclude that mass of air that has entered the tank is 7.80 kg.
Explanation:
given data
volume = 1.85 m³
density 1 = 1.18 kg/m³
density 2 = 5.30 kg/m³
solution
we know that density is the mass present in per unit volume so that is
mass = density × volume ........................1
here density is change so put here value in equation 1 we get
mass = ( 5.30 - 1.18 ) kg/m³ × 1.85 m³
solve it we get
mass = 7.807 kg
so we can conclude that mass of air that has entered the tank is 7.80 kg.
I don’t know the first one but the second one is light and the third one is a satellite
Positive acceleration increases speed. Negative acceleration reduces speed. Zero acceleration leaves speed unchanged.
Tin is very weakly attracted to magnets, but is not ferro magnetic. I would say it is magnetic even though it is very weakly attracted to it.
Kinetic friction, for example, generally turns energy into heat, and although we associate kinetic friction with energy loss, it really is just a way of transforming kinetic energy into thermal energy. The law of conservation of energy applies always, everywhere, in any situation. ?
