Explain why the pressure exerted by a gas does not depend on the type of the gas.

Explanation: the pressure exerted by a gas does not depend on the type of the gas because pressure is a physical force its has not chemical composition.

So, pressure depends upon the numbers of molecules of the gas because gas molecules collide with the wall of the vessel. They exert force on the wall and we know the pressure is force applied per unit area .

According to Gay - Lussac's law, the temperature of the gas is direct proportional to the pressure at a constant volume.

The pressure exerted by a gas depends on the number of gas particles present, according to the Kinetic Molecular Theory of gases. Other factors like volume of the particles or the intermolecular forces between molecules are assumed zero. So 50 particles of Helium gas exerts the same pressure of 50 particles of Oxygen gas.

A wagon has a mass of 100 grams and an

olga2289 [7]

Answer:

Net force on the wagon is 200 N

Explanation:

As we know by Newton's II law that net force on the system of mass is given as product of mass and acceleration

Here we know that

mass = 100 kg

a = 2 m/s/s

now we have

$F = ma$

$F = (100)(2)$

$F = 200 N$

Law Incorporation [45]

Answer:

<u>The magnitude of the friction force is 8197.60 N</u>

Explanation:

Using the definition of the centripetal force we have:

$\Sigma F=ma_{c}=m\frac{v^{2}}{R}$

Where:

m is the mass of the car
v is the speed
R is the radius of the curvature

Now, the force acting in the motion is just the friction force, so we have:

$F_{f}=m\frac{v^{2}}{R}$

$F_{f}=2100\frac{18^{2}}{83}$

$F_{f}=8197.60 \: N$

<u>Therefore the magnitude of the friction force is 8197.60 N</u>

I hope it helps you!

Which of the following statements are true? Positively charged objects attract other positively charged objects. Negatively char

butalik [34]

The statement that is true is that positively charged objects attract negatively charged objects. This is due to a law that states 'like forces attract while unlike forces repel. This same concept applies to magnetism. If you put two similar poles together, for example; if you place two south poles together. You feel a separating force between the two poles. But if you place two opposite poles together they attract each other. Hope i helped. <span />
