If A person weighing 75 kg stands on a scale on a elevator what will it read if the elevator is at rest?
well I would say using newtonian mechanics he would weight as F=M x g, 75x9.7 which equals 727.5 newtons.
Suppose that a 50.0 kg woman were standing on a bathroom scale in this elevator car what would the scale read?
On the way up:-Before the car started moving, it would read 490 newtons (110 pounds).-When the car started moving up, the scale would read more, until the car achieved its normal upward speed.-As long as the car maintained its steady normal speed, the scale would again read 490 newtons (110 pounds).-As the car approached its destination level and began to slow down, the scale would read less, until the car stopped.-When the car stopped, the scale reading would return to its normal 490 newtons (110 pounds).On the way down:-Before the car started moving, it would read 490 newtons (110 pounds).-When the car started moving down, the scale would read less, until the car achieved its normal downward speed.-As long as the car maintained its steady normal speed, the scale would again read 490 newtons (110 pounds).-As the car approached its destination level and began to slow down, the scale would read more, until the car stopped.-When the car stopped, the scale reading would return to its normal 490 newtons (110 pounds).================================All numbers are rounded. Acceleration of gravity is taken to be 9.8 meters (32.2 feet) per second2.
When you lift one foot when standing on a scale does your weight change?
No, lifting one foot while standing on a scale does not change your weight. The scale measures the force exerted downward on it, regardless of how many feet are on it.
Does a scale read more or less in an elevator that is accelerating upward?
It will increase! if the elevator is moving with a constant velocity, then there will be no change in the reading as no acc. will be caused. but if the body moves downwards wit a uniform acc. of say suppose x m/s^2, then the weight if the body will decrease by F=m x a(of the lift) as the two vectors will be in the opp direction, i.e. downwards. the opposite applies when the when the body acc. in an upward direction, the vectors will be in an same direction and it will result in the scale reading turing up more! remmember, a sacle measures the upward force aka reaction force
A 60 kg person stands on a scale in an elevator. (a) What does the scale read (in N) when the elevator is at rest N (b) What does it read when the elevator is climbing at a constant speed of 4.5 ms N?
We must use: (Force) = (Mass) x (Acceleration) Force = 400 N Acceleration = 9.8 m/(s^2) Mass = M 400 N = ( M ) x ( 9.8 m/(s^2)) After calculating, we find the mass of the man to be 40.82 kg.
What will a 50kgs on earth weigh in zero gravity?
If you had a 50kg weight on Earth, it would weigh ~zero on the space station. It would still have a mass of 50kg--meaning it would difficult to move, and hurt very bad if it wumped you on the head, but placed on a scale, it would show 0. Likewise, if you had that 50kg weight and a scale on an elevator here on Earth, the scale would read 50kg. Say at the top of a 100 floor building, the elevator's cable and safety devices broke and the elevator, you, the 50kg weight and the scale were all in free fall. For a very short time, the 50kg weight would weigh zero. You would weigh zero. The scale would weigh zero. Until the elevator hit the ground.

How high must a spacecraft be before weightlessness is detectable?
Its not a questions of height or altitude. Its about things free falling. A space ship falling around the Earth (everything in the space ship is also falling at the same speed) the astronauts are falling too. If you put a scale on the floor and an astronaut stepped on it, there is no downward force so it looks like they are weightless. Picture yourself in an elevator at the top floor. You're standing on a scale. Gravity pulls you and the scale, but the elevator floor prevent you from falling. The scale will measure your weight. If the elevator suddenly fell, it, you and the scale would all be accelerating towards the basement at 9.8m/s/s. The scale would read ZERO, because there is no force acting on the scale.
What would your scale read if you weighed yourself on an inclined plane?
The same as if you were not standing on your head.

Suppose the scale of a bar graph is 048122620 describe the bar that would represent the number 10?
peanut butter
What did Loma Prieta reach on the Richter scale?
Most sources say either 6.9 or 7.1 so i suppose it would be 6.9-7.1
What would happen if you are standing on a weighing scale and all of a sudden the atmosphere vanished The reading on the scale would?
The reading on the scale would remain the same. Weight is a measurement of the gravitational force between you and the Earth, not the atmospheric pressure. Without the atmosphere, the force of gravity would still act on you, keeping your weight constant.
If an average person sits on a scale how much more would it show standing up?
Add leg weight, roughly 45#.
