The choices can be found elsewhere and as follows:

a. A hypothesis does not provide an explanation but instead only predicts what may happen.
b. A theory does not provide an explanation but instead only predicts what may happen.
c. The explanation given by a theory is well tested and supported by many observations and hypotheses.
<span>d. The explanation given by a hypothesis is well tested and supported by many observations and theories.
</span>
I think the correct answer from the choices listed above is option A. A hypothesis does not provide an explanation but instead only predicts what may happen. Hope this answers the question. Have a nice day.

I'm not sure about the rest but for question 2:

A theory is an attempt to come up with a big picture of all we know so far. It also drives future research as people do experiments to see if what the theory predicts actually happens. When experiments don’t support the theory, you have to change the theory and try again. That’s how science works. We come up with a “best guess” (theory), and then do research to test it’s accuracy. As we discover contradictions, we adjust the theory to take those into account, and then start testing the validity of the new theory.

Determine the velocity required for a moving object 2.00 x 10^4 m above the surface of Mars to escape from Mars's gravity. The m
Ket [755]

Answer:

Therefore the escape velocity from Mar's gravity is 15.88 \times 10^4 m/s.

Explanation:

Escape velocity: Escape velocity is a the minimum velocity that a object needs to escape from the gravitational field of massive body.

V_{escape}=\sqrt{\frac{2GM}{R}}

V_{escape}= Escape velocity

G=Universal gravitational constant = 6.673×10⁻¹¹N m²/Kg²

M= mass of Mars = 6.42×10²³ kg

R = Radius of the Mars = 3.40×10³m

The escape velocity does not depend on the velocity of a object.

V_{escape}=\sqrt{\frac{2\times6.673\times 10^{-11}\times 6.42\times 10^{23}}{3.40\times10^3}}

           =15.88 \times 10^4 m/s

Therefore the escape velocity from Mar's gravity is 15.88 \times 10^4 m/s.

Answer:

\huge\boxed{Divide\ distance \ by \ time}

Explanation:

Speed = Distance / Time

So, to find distance, we actually divide distance by rime.
