PLS HELP! If a person has a weight of 600 N, how much will they weigh on the Moon?

Physics
2 answers:
nordsb [41]4 years ago
5 0

Explanation :

It is given that, the weight of the person on the earth is 600 N. The weight is equal to :

W = m g

where

g is the acceleration due to gravity on the earth, g = 10 m/s²

600\ N=m\times 10\ m/s^2

m = 60 kg

We know that the mass of an object remains constant everywhere.

The value of g on moon is, g' = 1.63 m/s²

So, W' = m g'

W'= 60\ kg\times 1.63 m/s^2    

W' = 97.8 N

Hence, the weigh on the moon is 97.8 N.

Which list places the layers of the sun in the correct order from innermost to outermost?
LiRa [457]

Answer:

Convective zone, chromosphere, corona

Explanation:

A star like the Sun is divided into different layers according to pressure, density, temperature, and the mechanics of energy transport (in the case of the convective zone and radiative zone) for each of those layers.

In stars, there is an equilibrium between two forces, the force of gravity in the inward direction due to their own mass and the radiation pressure in the upward direction as a consequence of the nuclear reaction in their core, that is known as hydrostatic equilibrium.

That leads to different layers according with the properties described above.    

       

Near the core, in the Sun, there is a radiative zone since radiation is the best mechanism of energy transport in this area. Then, in the next layer, it can be found that convection becomes a more efficient way of energy transport that radiation due to the fact that the inner part of the convection zone is at a greater temperature than the outer one.    

Finally, there is the atmosphere of the Sun (chromosphere, photosphere, and corona).

                                       

Key terms:        

Convection: Transport of energy due to different in density and temperature of a material (liquid, gas).

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.

Dan is gliding on his skateboard at 2.00 m/s . He suddenly jumps backward off the skateboard, kicking the skateboard forward at
miss Akunina [59]

Answer:

The velocity of Dan is 1.13 m/s.

Explanation:

Given that,

Initial velocity of skateboard and Dan = 2.00 m/s

Velocity of skateboard = 7.00 m/s

Mass of Dan m= 40.0 kg

Mass of skateboard M= 7.00 Kg

Suppose How fast is Dan going as his feet hit the ground?

We need to calculate the initial velocity of Dan

Using conservation of momentum

(m+M)v_{i}=mv_{f}+Mv_{f}

Put the value into the formula

(40.0+7.00)\times2.00=40.0\times v_{i}+7.00\times7.00

v_{i}=\dfrac{(40.0+7.00)\times2.00-7.00\times7.00}{40.0}

v_{i}=1.13\ m/s

Hence, The velocity of Dan is 1.13 m/s.
