-- "Weight" is the gravitational attraction between TWO objects.
-- Its 'strength' depends on the mass of BOTH masses.
If either mass changes, then the gravitational force between them changes.
-- Your 'weight' on Earth depends on your mass and the Earth's mass.
-- Your 'weight on the moon depends on your mass and the Moon's mass.
From the list of choices, the best one is "The Earth and moon have
different values for the acceleration due to gravity.", although that
doesn't really explain much.
Answer: The correct option is A.
Explanation:
Inertia is a state of an object or body to maintain its state. It resists any change in its state.
Newton's first law of inertia: When an objects is in state of motion, it will remain its state of motion or if it is in state of rest then it will remain in rest unless it is acted upon by external motion.
In the given options, a ball sits motionless on the ground is good example of Newton's first law motion. No external force is acting in this case.
In options (B), (C) and (D) , the external force is acting.
Therefore, the correct option is A.
Observations are used in order to collect data and record a variety of interesting or useful key points about the subject or specimen in observation. These observations, if made well, can be recorded and used to supplement a hypothesis.
Answer:
The answer is below
Explanation:
Charlee's law states that the volume of a gas is directly proportion to the temperature of the gas at constant pressure. That is:
V = kT, where V = volume and T = temperature, k = constant. Therefore:
V / T = k
Given that: 
The new volume is 3.41 m³. That is it expands by 0.41 m³
