Quasar spectra often show many absorption lines that all appear to be as a result of the same electron transition (such as level
Elanso [62]

Answer: Because of different redshift of cloud.

Explanation:

We are seeing absorption lines from clouds of gas that lie between us and the quasar, and therefore each cloud has a different redshift.

A quasar's spectrum is hugely redshifted. And most astronomers think this large redshift tells us about the distance to the quasar.

Wile E. Coyote is chasing the roadrunner and falls off a cliff. It takes Wile E Coyote 7 long seconds to hit the ground. How hig
mart [117]

Answer:

240.1m  

Explanation:

Given parameters:

Time taken to hit the ground  = 7s

Unknown:

Height of the cliff = ?

Solution:

To solve this problem, we use the right motion equation expressed below:

             S = ut + \frac{1}{2} gt²

S is the height of the cliff

u is the initial velocity  = 0m/s

g is the acceleration due to gravity  = 9.8m/s²

t is the time taken

Now, insert the parameters and solve the problem;

      S = (0 x 7) + ( \frac{1}{2}  x 9.8 x 7²)

     S = 240.1m

Machmer Hall is 400 m North and 180 m West of Witless.
yan [13]

Answer:

The distance from Witless to Machmer is 438.63 m.

Explanation:

Given that,

Machmer Hall is 400 m North and 180 m West of Witless.

We need to calculate the distance

Using Pythagorean theorem

D = \sqrt{(d_{m})^2+(d_{w})^2}

Where, d_{m} =distance of Machmer Hall

d_{w} =distance of Witless

Put the value into the formula

D = \sqrt{(400)^2+(180)^2}

D=438.63\ m

Hence, The distance from Witless to Machmer is 438.63 m.
