If a man weighs 720 N on the Earth, what would he weigh on Jupiter, where the free-fall acceleration is 25.9 m/s2

On Jupiter, the man would weigh  1.903 kN

Explanation:

Given that;

a mans weight is 720 N

on earth, g = 9.8 m/s²

so mass on earth will be;

m = F/g = 720 / 9.8 = 73.4693 kg

In Jupiter, g = 25.9 m/s²

so the man's weight in Jupiter will be;

F = mg

F = 73.4693 × 25.9

F = 1902.8549

F = 1.903 kN

Therefore, on Jupiter, the man would weigh  1.903 kN

absorption lines are where light has been absorbed by the atom thus you see a dip in the spectrum whereas.

emission spectra have spikes in the spectra due to atoms releasing photons at those wavelengths.

explanation:

be subject to a force andchange its motion
