Question

What is the relationship between gravity and pressure in a nebula?

A.) Gravity reduces pressure.
B.) Pressure balances gravity.
C.) Pressure increases gravity.
D.) None of the above.

Answer 1

Correct answer choice is :

B) Pressure balances gravity.

Step-by-step 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 2

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.
