The same net force is applied to two bodies. The first body acquires half of the acceleration of the second body. What is the re
Yanka [14]

The mass of the first body is double the mass of the second body.

This all revolves around Newtons 2nd law of motion that states F=m*a.

If we understand that body one has the same force applied but half of the acceleration than body two, we can easily understand that it has to do something with the objects mass. This is because mass and acceleration in newtons 2nd law are inversely proportional. This means if and objects force stays the same, but it’s mass doubles, then the acceleration must be half its original value. And if the acceleration doubles and the force stays constant than the mass must have halved from its original value. It sounds quite complicated but it’s very simple. Hopefully this helps!!!

Two sources of error and precaution in the centre of gravity experiment​
Karo-lina-s [1.5K]

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
  • pencil

Procedure:

  1. Cut the cardboard into a strange shape.Do not use a circle,square,rectangle,or any other common geometric shape.
  2. Punch a hole near the edge of the cut-out cardboard piece and hang it from a nail.
  3. Place the weight, a washer or bolt, on a thread and tie it off.
  4. Hang the thread and weight from the nail in front of the cardboard.
  5. 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:

  1. 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.
  2. 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.
  3. 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.
  4. 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.
  5. 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.

A cube of wood is floating on water. a cube of iron is totally submerged in water. the cubes are equal in volume. which cube has
-BARSIC- [3]
The one that's completely submerged is displacing more water, so the buoyant force on it is greater.

Pls hurry, i'm timed TmT
solong [7]

According to the introduction, why are black holes invisible?

the answer is in the first paragraph :)

"Black holes are invisible because they have so much gravity that nothing escapes. Not even light can escape or bounce off."

hope this helped !

Why do rivers usually have water in them, even during a drought?
Kipish [7]
Well the case with the droughts is that the water supply comes from different places such as other smaller streams and also from underground rivers .Rivers cut into saturated ground is also another reason.
