The average lifetime of a poodle dog is 13.0 years. how fast is it traveling, u, relative to an observer who measures the average lifetime to be 50.0 years? 4

The speed is 0.97 c.

Explanation:

Given that,

Dilated time t'= 50.0 years

Rest time t = 13.0 years

We need to calculate the speed

Using formula of time dilation

Where, t' = change in time

t = rest time

v = velocity

c = speed of light

Put the value into the formula

Hence, The speed is 0.97 c.

wavelength variability is the right one

less than one you can't create energy
