The relationship between gravity and pressure in a nebula is that pressure balances gravity. The pressure exerted by a static fluid depends only upon the depth of the fluid, the density of the fluid, and the acceleration of gravity. The answer is B.

Correct answer choice is :

B) Pressure balances gravity.

Explanation:

A nebula is an interstellar fog of dust, hydrogen, helium and other ionized gasoline. Basically, the nebula was a title for any scattered large object, including universes behind the Milky Way. Most nebulae are of a large size, some are numbers of light years in diameter. A nebula that is almost obvious to the human eye from earth would seem larger, but no brighter, from close by. The Orion Nebula, the glowing nebula in the sky that involves a range twice the width of the full Moon, can be observed with the naked eye but was dropped by early scientists.

Answer:

4.03 m/s

Explanation:

Initial momentum = final momentum

(282 kg) (3.50 m/s) + (155 kg) (-1.38 m/s) = (282 kg) (1.10 m/s) + (115 kg) v

v = 4.03 m/s

Semenov [28]

Answer:

a) $A_1 = \frac{\pi d_1^2}{4}$

Explanation:

a) the cross-sectional area of the hose would be the square of radius times pi. And since the sectional radius is half of its diameter d. We can express the cross-sectional area A1 in term of diameter d1

$A_1 = \pi r_1^2 = \pi (d_1/2)^2 = \frac{\pi d_1^2}{4}$

Answer:

Newton's second law of motion describes the relationship between force and acceleration. They are directly proportional. If you increase the force applied to an object, the acceleration of that object increases by the same factor. In short, force equals mass times acceleration.

You can't see beyond a blind turn, so a mirror would allow you to see around the corner.
