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

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.

How fast is a meter stick moving with respect to you if it appears as 0.5 m long to you?

Answer and Explanation: 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 fast must a meter stick be moving if its length is observed to shrink to 0.500 m?

Expert-Verified Answer Hence, for the length of the metre stick to be observed to shrink to 0.500m, it must be moving at a rate of roughly 0.866 times the speed of light, or about 259,800 km/s.

What would you measure its length to be if a meter stick moves to your right at a constant velocity of 0.8 c?

Expert-Verified Answer Its length in this scenario will be equal to 0.6meters.

How do you find the reaction time of a meter stick?

We can use the distance the meter stick fell before you caught it to figure out your reaction time. The following formula is the basis: d = 1/2 gt2. In this formula, “d” equals the distance the object fell, “g” equals gravitational acceleration (9.8 m/s2), and “t” is the time the object was falling.

What is the speed of light to an observer?

The speed of light is constant relative to everything. What Newton – and later, Einstein – showed was that there is no underlying reference frame; all motion is relative. Light differs only in that everyone perceives light to have the same relative speed; 299,792,458m/s in a vacuum.

What is the accuracy of the meter stick to cm?

We can say that the measuring instrument is readable to ±0.05 cm. The ±0.05 cm means that your measurement may be off by as much as 0.05 cm above or below its true value. This value is called the uncertainty or the precision of the instrument.

What is the value of the smallest line on a meter stick?

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.

Is the length of a meter stick exactly 1 m?

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.

What is the metre rule of length?

A metre rule has a length of one metre, which is equal to one hundred centimetres, as the name suggests. A metre ruler has a length of one metre, which is equal to one hundred centimetres, as the name suggests.

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.

What is the measurement that tells us how fast an object is moving?

Speed is the rate at which an object’s position changes, measured in meters per second. For example, if an object starts at the origin, and then moves three meters in three seconds, its speed is one meter per second. The equation for speed is simple: distance divided by time.

Is a meter stick longer than a ruler?

You can measure objects using different tools. A meter stick is longer than a ruler. lengths.

How is a meter stick measured?

Metersticks are usually divided with lines for each millimeter (1000 per meter) and numerical markings per centimeter (100 per meter), with numbers either in centi- or millimeter. Yardsticks are most often marked with a scale in inches, but sometimes also feature marks for foot increments.

What is the formula for length contraction?

Length contraction L is the shortening of the measured length of an object moving relative to the observer’s frame: L=L0√1−v2c2=L0γ. L = L 0 1 − v 2 c 2 = L 0 γ .

What is the time in seconds that it takes for light to travel 1 meter in a vacuum?

Light travels at a speed of approximately 300,000 km/s or 3×108 m/s. Therefore, it would take approximately 1/3×108 = 3.33×10-9 seconds, or 3.33 nanoseconds, for light to travel 1 meter. This means that the time taken for light to travel through a vacuum is almost instantaneous.

How long does it take for the speed of light to travel 1 meter?

So a metre is now how far light travels in 1299,792,458 second.

What is the length of an object measured by an observer at rest relative to the object?

Answer and Explanation: An object’s proper length is measured by an obsever (b) who is at rest relative to the object. The proper length of an object is defined as the length of an object before it starts moving at relativistic speeds.

What is the speed relative to the observer?

The greater the speed of an object relative to an observer, the greater the object’s mass appears to the observer. This effect is conspicuous only at speeds near the speed of light c, which is 3 x 108 m/s, about 186,000 mi/s.
