Answer:
(c.) as the force of Earth's gravity on an object increases, the object's mass increases
Explanation:
Based on newton's law of gravitation "every particle of matter in the universe attracts every other particle with a force that is directly proportional to the product of the masses of the particles and inversely proportional to the square of the distance between them".
It is mathematically expressed as:
F = 
F is the gravitational force on either particle
m₁ and m₂ are the masses
r is the distance between particles
G is the universal gravitation constant.
From this expression, we see that the force of earth's gravity is directly proportional to mass.
That statement is False.
Most metals are in the solid state at room temperature. The only metal that is in liquid state in the room temperature is Mercury, (Hg)
Density=mass/volume
density=2/8
density=0.25g/ml
Answer:
The pressure in the gas is 656mmHg
Explanation:
In calculating the pressure of the gas;
step 1: convert the height of the mercury arm to mmHg
9.60cm = 96.0 mmHg
step 2: convert 752 torr to mmHg
I torr is 1 mmHg
752 torr = 752mmHg
Step 3: since the level of mercury in the container is higher than the level of mercury exposed to the atmosphere, we substrate the values to obtain our pressure.
So, 752mmHg - 96mmHg = 656mmHg
The pressure in the gas container is therefore 656mmHg.
N. B : if the mercury arm is in lower position, you add.
