Answer:
See the anwers below
Explanation:
To solve this problem we must understand that the weight of any![W = 0.1*10\\W = 1 [N]](https://tex.z-dn.net/?f=W%20%3D%200.1%2A10%5C%5CW%20%3D%201%20%5BN%5D)
body is defined as the product of mass by gravitational acceleration. Gravitational acceleration depends on the place in space where a certain body is located.
where:
W = weight [N]
m = mass = 100 [g] = 0.1 [kg]
g = gravity acceleration [m/s²] or [N/kg]
<u>Now for the Earth</u>
<u />![W =m*g\\W =0.1*10\\W = 1[N]](https://tex.z-dn.net/?f=W%20%3Dm%2Ag%5C%5CW%20%3D0.1%2A10%5C%5CW%20%3D%201%5BN%5D)
<u />
<u>For the Moon</u>
<u />![W = m*g\\W =0.1*1.6\\W = 0.16 [N]](https://tex.z-dn.net/?f=W%20%3D%20m%2Ag%5C%5CW%20%3D0.1%2A1.6%5C%5CW%20%3D%200.16%20%5BN%5D)

The dependence of a measured value on a controlled value should be the correct answer.

Answer:
The answer to this question is given below in this explanation sections.
Explanation:
The weight of an object is concentrated at the center of gravity.The term center of gravity is used interchangeably with center of mass.For a symmetrical object the center of mass is located at the geometric center of the object.If the object is not symmetric we can determined the center of mass using the mentioned below.
Materials:
- cardboard
- weight(washer,bolt,or fishing weight)
- hole punch
Procedure:
- Cut the cardboard into a strange shape.Do not use a circle,square,rectangle,or any other common geometric shape.
- Punch a hole near the edge of the cut-out cardboard piece and hang it from a nail.
- Place the weight, a washer or bolt, on a thread and tie it off.
- Hang the thread and weight from the nail in front of the cardboard.
- use a pencil to draw a plumb line down the cardboard where the thread touches.This mark your center line from that hanging point.
conclusion:
What would happen to the center of gravity of the shape if you were to spin it freely?
center of gravity experiment:
- Balance a ruler with a hammer.Take a rubber band or string and make a loose loop around the hammer and ruler. Make sure the end of the hammer is touching the ruler,and then positions the ruler at the edge of the table.
- Balance two forces with a toothpick.A common magic trick using the properties of center of gravity.The two forks are balanced on the edge of the glass by a toothpick.
- Stand with your back and feet against a wall.Have someone place quarter on the floor at your feet.Try to pick it cup.Most people cant make these adjustments.
- Stand against a wall sideways with your arm and leg touching the wall,with nothing to from the out away hold onto.Try to lift your other leg straight out away from the wall.you wont be able to do it.
- The girls away win chairs lifting challanges place dining chairs against a wall.Bend over the chair so that your head touches the wall and you upper body is parallel to the floor.lift the chair to your chest to your chest and then try to stand up.
Firstly, you must identify the pure substance first. Then, from a reliable source obtain its density. Density is calculated through the equation,
density = mass / volume
From this equation, the volume can be calculated.
volume = mass / density
