The gravitational effect on
other bodies determines the weight (or the mass) of a planet. We
must somehow measure the strength of its "tug" on another object in
order to use gravity to find the mass of a planet. We can harness Newton's
equations to deduce what the mass of the planet must be through observing
the time it takes for the satellite to orbit its primary planet.
Given:
Mass of Venus = 4.87 x 1024 kg
= 4986.88
Mass of Jupiter = 1.898 x 1024 kg
= 1943.552
Mass of Jupiter compared to mass of
Venus
1943.552 / 4986.88
= 0.3897330595482546
= 0.3897330595482546 x 100%
= 38.97%
So, in this problem, <span>the mass of Jupiter is about 0.39 times the mass of Venus.</span>

The Answer is D. Because It's the part thats reflecting
Answer:
= - 26.31 kJ
Explanation:
we know that number of moles is calculated as
= 0.00476 mol
Heat absorbed by calorimeter
= 26.87 kJ
Enthalpy of combustion
= - 55290.12 kJ/mol
Negative sign shows that the heat is released
The balanced reaction
ΔHc = ΔU + Δng (RT)
-55290.12 = ΔU + (12 - 12) *(RT)
= - 26.31 kJ
