## How fast must a meter stick be moving if its length is measured to shrink to 0 500 m?

In order to observe a meter stick to shrink its length to 0.5 meters, it must move at a speed of 2.6 × 10 8 m s .

## How much time does a meter stick moving at 0.1 C relative to an observer take to pass the observer?

The formula for time is: t = d/v where t is the time, d is the distance, and v is the velocity. 4. Substituting the values into the formula, we get: t = 0.995m / 0.1c t ≈ 3.32 * 10^-9 seconds So, it takes approximately 3.32 nanoseconds for the meter stick moving at 0.1c to pass the observer.

## Is a meter stick 100 cm long?

A meter stick is exactly 1 meter (100 cm) long. In terms of feet, it is a little bit more than 3 feet (about 3.2 feet long). It is because 1 meter is approximately equal to 3.28084 feet. A meter stick is 1 meter long, which is divided into 100 centimeters.

## How many cm is meter stick?

A meter has 100 centimeters.

## How fast must a meter stick be moving if its length is observed to shrink to half its original size?

Final answer: The meter stick must be moving at a velocity of approximately 2.71 × 10^8 m/s.

## How much longer is a meter stick?

A meter stick is a little over 3 feet long, because a meter is approximately 3.2 feet. A meter stick closely compares to a yard stick. For instances where a yard stick would be used for customary units, a meter stick would be used to measure metric units.

## What is the speed of light in relativity observer?

The speed of light is constant relative to any observer, no matter what speed he may be travelling relative to any other observer.

## What is the speed of light relative to the moving observer?

The speed of light is absolute; that means it is the same seen by any observer, no matter how fast the observer is moving relative to the light source. THE OBSERVED SPEED OF LIGHT IN A VACUUM IS ALWAYS 299,792.459 KILOMETERS PER SECOND.

## What happens to the length of a rod when observed by an observer moving at very high speed with respect to it?

The observer that sees it passing, lying in the direction of travel, sees a shorter version of it. Other observers moving in the same direction but at different speeds will see other versions of it with different lengths, all shorter than its proper length.

## Which is more 1 meter or 1000 millimeters?

1000 millimeters = 1 meter.

## Is a meter stick 1 meter?

To measure things which are longer than 30 centimeters, we use a meter stick. A meter stick is 100 centimeters, which is one meter long.

## How long is 2 meter sticks in feet?

Meter (m) | Feet (ft) |
---|---|

2 m | 6.5616 ft |

3 m | 9.8425 ft |

4 m | 13.1233 ft |

5 m | 16.4041 ft |

## What is the smallest length your meter stick can measure?

That is, the millimeter is the smallest subdivision on the meter stick, which can be seen in Figure 1. This means the millimeter is the unit of the smallest reading that can be made without estimating.

## Would the length of an object be zero if the object were moving at the speed of light?

This is a very difficult concept to grasp, but it is true. When an object (with mass) is in motion, its measured length shrinks in the direction of its motion. If the object reaches the speed of light, its measured length shrinks to nothing.

## Is the length of a meter based on how fast blank travels in a vacuum?

The meter is defined as the distance traveled by light in vacuum in 1/299792458 sec.

## Can you measure distance smaller than 1 mm on meter rule?

Least Count: Least Count of an instrument is the smallest measurement that can be taken using an instrument. In other words, it is the smallest change an instrument can measure. For example, the ruler can measure a minimum 1 mm length.
