2. density
3. control
4. matter
5. accuracy
6. gradation
<u>Explanation</u>
1. An indication of how close a measurement is to the correct result is called precision.
2. The mass of a substance per unit volume is called density of a substance.
3. A quantity in an experiment that remains unchanged or constant is called a control group.
4. Anything that has mass and occupies space is called matter.
5. The degree to which a measurement can be replicated is called accuracy.
6. Scale markings that denote equal units of measure is called gradation.
Answer:
2 x 10^20 N
Explanation:
Me = 5.98 x 10^24 kg
Mm = 7.36 x 10^22 kg
r = 3.82 x 10^5 km = 3.82 x 10^8 m
The gravitational force between earth and moon is
F = G Me x Mm / r^2
F = (6.67 x 10^-11 x 5.98 x 10^24 x 7.36 x 10^22) / (3.82 x 10^8 x 3.82 x 10^8)
F = 2 x 10^20 N
A. Mass
Explanation:
Inertia is a property that is directly related to mass of a body. It can be defined as a property that causes a body to resist change in its state of motion.
- Newton's first law of motion is known as the law of inertia.
- The law state's that "an object will continue to be at rest or in uniform motion unless if it is being acted upon by an external force".
Inertia is related to force and it can be calculated using the expression below:
Inertia = m x a
where m is the mass of the body
a is the acceleration of the body
From this, we see that the more the mass of a body, the more its inertia and its reluctance to change its state of motion.
Therefore mass is directly related to inertia.
