When scientists talk about the expanding universe, they mean that it has been growing ever since its beginning with the Big Bang. ... In other words, the universe has no center; everything is moving away from everything else.

Mamont248 [21]

Answer:

Option B

Technician B only is correct

Explanation:

Technician a is wrong because the rupture was not caused by switching DOT (Department of Transportation) 3 and DOT 4 Brake fluids. As a matter of fact both brake fluids are compatible with most vehicular systems, and to a certain extent they can be used interchangeably without any adverse effect.

Technician B on the other hand, gives a more accurate reason, since a twisted brake hose will definitely fail and rupture once enough force is applied to it, which is most likely the case of what happened considering the mileage it ran before rupturing. Within this mileage, it is very possible for the pressure on the already twisted brake hose to have been damaging it gradually before finally making it to rupture.

nalin [4]

Answer:

Atlanta is at 596.0 km from the house.

Explanation:

The distance between Atlanta and the house can be found using the following equation:

v = \frac{d}{t}   (1)

Where:

v: is the speed = 80 km/h

t: is the time = 7.45 h

By solving equation (1) for d and entering the above values we have:

d = v*t = 80 km/h*7.45 h = 596.0 km = 596000 m

Therefore, Atlanta is at 596.0 km from the house.

I hope it helps you!
