A481-m long spaceship passes by an observer at the speed of 2.70×10^8 m/s. what length does the observer measure for the spaceship?

209.66 m

Explanation:

Given:

Original length of the spaceship, L = 481 m

Speed of the spaceship, v = 2.70 × 10⁸ m/s

Now,

using the concept of length contraction, we have

where,

L' is the observed length

c is the speed of the light

Thus,

on substituting the respective values, we get

or

L'  = 209.66 m

explanation:

areas w steep slopes, west coast, rocky mountains, and appalachian mountains

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.
