c.
reversing.
b.
contracting.
d.
stagnant.

Answers

Answer 1
Answer:

An observation of the red shift of galaxies suggests that the universe is expanding. The answer is letter A. .  It means that bodies farther away from Earth were moving away faster. The Hubble’s constant is the ratio of distance to redshift equal to 170 kilometers per second per light year of distance.

What leads to the development of the theory?

Answers

Theories are developed when phenomena are observed and analyzed using the scientific method or another method of inquiry to determine if their are observable similarities and causalities which can be created into a theory. The development of theories helps to understand the physical world by providing an order and way of seeking to understand and explain the way that the world and universe are ordered or unordered.

When two forces act on an object in the same direction the resultant force is equal to

Answers

When two (or more) forces act on an object, all in the same direction,
the resultant force is equal to the sum of the individual forces.

That's a big part of the reason why, when you're pushing a car, you
ask somebody else to come push it with you, in the same direction.

An electron is pushed into an electric field from infinity where it acquires a 1-V electrical potential. Suppose instead that two electrons are pushed from infinity the same distance into the same electric field. The electrical potential of the two electrons is ___________.a) 0.5V
b) 1V
c) 0.25V
d) 4V
e) 2V

Answers

Answer:

The electrical potential of the two electrons is 1 V.

(b) is correct option.

Explanation:

Given that.

Electric potential = 1 V

We know that,

The electric potential depends on the distance.

The electric potential does not depend on the charge.

The formula of electric potential

V=Ed

Where, E = electric field

d = distance

Hence, The electrical potential of the two electrons is 1 V.

True or false The Coriolis effect is caused by the jet stream.

Answers

The answer is false. The Coriolis effect is not caused by the jet stream. It is caused by the rotation of the Earth. The Coriolis effect is the apparent reversal of rotation of storms and the direction when draining water in the sink or toilet when you cross the equator. In the Southern hemisphere, the rotation is clockwise and in the Northern hemisphere, it's counter-clockwise.

its false guys this easy
