What is the uncertainty in the measurement for the speed of light?
The length of a meter.
If a meter stick moving at 0.90 of the speed of light with respect to the observer would appear to be how long?
--> To get the answer you're interested in, we have to specify that the stick is lined upwith its length of 1 meter pointing in the direction of the motion. It doesn't do any goodto have it standing up straight but moving horizontally. The contraction is only in thedirection of motion.The contracted length = L sqrt(1 - v2/c2) =1 sqrt(1 - 0.81c2/c2) = 1 sqrt(0.19) = 0.436 meter
How do astronomers determine the speed at which a galaxy is moving?
By examining its spectrum, and identifying absorption lines in it. Lines are shifted toward shorter wavelength if the object is moving towards us. They're shifted toward longer wavelength if the object is moving away from us.
What units for distance is an SI unit?
The S.I. unit of distance is the metres, which is basically the distance between any two points.
What is the si standard unit for measurement or lengths?
Its based on the speed of light.
What is the uncertainty in the measurement for the speed of light?
The length of a meter.
Is speed meter measure velocity?
no ... not SPEED OF A MOVING CAR ......IT is to measure the average speed of a carThis can help :DRoy , Brunei
What has mass volume and density but not length?
An object moving at the speed of light.
The magnitude of the voltage induced in a conductor moving through a stationary magnetic field depends on the what?
The magnitude of the voltage induced in a conductor moving through a stationary magnetic field depends on the length and the speed of the conductor.
How fast is a wave moving if its wave length is 10 meters and its frequency is 110 Hz?
The formula for a wave in this case is: speed = frequency x wavelength. Since Hz = 1/second, the answer will be in meter/second.

SI units for time length speed and velocity?
SI units: time:second length: meter speed:meter/second velocity:meter/second.
How was the length of the standard meter redifined in 1983?
standard was changed to be associated with the constant speed of light
What happens if the source of a sound is toward you at a high rate of speed?
If the source of a sound is moving towards you, then the pitch of the soundyou hear is higher than the pitch of sound that the source is actually emitting.The rate of speed doesn't matter.BTW ... this also happens if you are moving toward the source.

How is wave length related to frequency fro waves moving at a constant speed?
Wavelength x frequency = speed of the wave.
What is the Direction of Acceleration of an object moving on any circular path at constant speed is pointed?
In toward the center of the circle.
