If a rod is moving at a velocity equal to 1/2 the speed of light parallel to its length, what will a stationary observer observe about its length?

The length of the  is 0.866 L₀.

Explanation:

Given that,

Velocity of rod = half the speed of light

We need to calculate the length

Using formula of length

Where, L= length

v = velocity of rod

c = speed of light

L₀ = observer length

Put the value into the formula

The length of the rod will decreases

Hence, The length of the rod is 0.866 L₀.

c. 7/3

step-by-step explanation:

a rational number is like pi- it is a repeating decimal.

a. is -1.8

b. 2.236068

c. 2.3333333333333333333

d.   is 3

i hope that ! =)

answer: i'm not sure which is which for i get confused on it all the time but i can tell you that the answer lies with the convex and concave devices. i hope this you. have a good day and best of luck to you!
