Answer:
change in gravitational potential energy Δ PE = 392 J
Explanation:
given data
mass of the person m = 80 kg
height of the centre of mass Δh = 0.50 m
to find out
change in gravitational potential energy
solution
we get here change in gravitational potential energy that is express here as
change in gravitational potential energy Δ PE = m × g × Δh .........1
put here value we get
change in gravitational potential energy Δ PE = m × g × Δh
change in gravitational potential energy Δ PE = 80 × 9.8 × 0.50
change in gravitational potential energy Δ PE = 392 J
Explanation:
0.566kg *(1mol/0.197 kg)= 2.87 mol gold
note how the units cancel out, if the units do not cancel out (kg/kg=1) then u did something wrong
Object #1 is very large; it has rings and many moons.
It's most likely the outer planet Saturn.
Object #2 is very small; it has no rings and a few moons but not many.
This one is most likely the inner planet Mars.
