Which statement about gravitational force is most accurate?

1 answer:

7 0

Gravitational force is the force of attraction. This kind of force forms an action-reaction in a situation.

<h3>What is gravitational force?</h3>

Gravitational force is the force present that is directly proportional to the masses and inversely to the square of the distance present from the center of the masses.

It is independent of the medium and remains constant in any matter whether it is water, air, or soil. It is conservative and is a central force that obeys Newton's law of motions.

Therefore, the gravitational force follows the action and reaction.

Answer:

radius = 156 pm

Explanation:

The relation between radius and edge length of unit cell of BCC is

r=a $\sqrt{3}$ /4

Given

a = 360 pm

Therefore

r = r = radius = 360 $\sqrt{3}$ /4= 155.88 pm

<u>Answer:</u> The partial pressure of helium gas is 0.80 atm

<u>Explanation:</u>

Dalton's law of partial pressure states that the total pressure of the system is equal to the sum of partial pressure of each component present in it.

To calculate the partial pressure of helium gas, we use the law given by Dalton, which is:

$P_T=p_{He}+p_{O_2}$

We are given:

Total pressure of the cylinder, $P_T$ = 1.00 atm

Vapor pressure of oxygen gas, $p_{O_2}$ = 0.20 atm

Putting values in above equation, we get:

$1.00=p_{He}+0.20\\\\p_{He}=1.00-0.20=0.80atm$

Hence, the partial pressure of helium gas is 0.80 atm
