First of all, the question is worded somewhat ambiguously because mass does not necessarily imply that there is a force (i.e. an object could be stationary in a system with no gravity and not have a force, or something of the like). Moreover, simply because an object is twice the mass does not mean the force will change.
However, we know from Newton's second law that F = ma. Therefore, force will increase or decrease proportionally with mass. This means if an object maintains a contestant acceleration and its mass doubles, the force that it provides will also double.

I just took the quiz and got 100% when choosing A.Conservation. Hope this helps:)
If im correct the answer is gravity
and wind resistance if you lift it fast

Answer:
Acceleration, 
Explanation:
It is given that,
Time period of revolution of the moon, 
If the distance from the center of the moon to the surface of the planet is, 
The radius of the planet, 
Let a is the moon's radial acceleration. Mathematically, it is given by :
, R is the radius of orbit
Since, 
The radius of orbit is,
So, 
Hence, this is the required solution for the radial acceleration of the moon.
Answer:
The total amount of CO₂ produced will be = 20680 kg/year
The reduction in the amount of CO₂ emissions by that household per year = 3102 kg/year
Explanation:
Given:
Power used by household = 14000 kWh
Fuel oil used = 3400 L
CO₂ produced of fuel oil = 3.2 kg/L
CO₂ produced of electricity = 0.70 kg/kWh
Now, the total amount of CO₂ produced will be = (14000 kWh × 0.70 kg/kWh) + (3400 L × 3.2 kg/L)
⇒ The total amount of CO₂ produced will be = 9800 + 10880 = 20680 kg/year
Now,
if the usage of electricity and fuel oil is reduced by 15%, the reduction in the amount of the CO₂ emission will be = 0.15 × 20680 kg/year = 3102 kg/year
