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.

Find the magnitude of the sum of two vectors; A is 5 km , and B is 7 , when the angle btween them is 120

Dimas [21]

Answer: 6.24 km

Explanation:

Given

The magnitude of the first vector(say) $\left | a\right |=5\ km$

the magnitude of the second vector(say) $\left | b\right |=7\ km$

the angle between them is $120^{\circ}$

The resultant vector magnitude is given by

$\left | \vec{R}\right |=\sqrt{a^2+b^2+2ab\cos \theta}$

$\left | \vec{R}\right |=\sqrt{5^2+7^2+2\times 5\times 7\cdot \cos 120^{\circ}}\\\left | \vec{R}\right |=\sqrt{74-35}=\sqrt{39}\\\left | \vec{R}\right |=6.24\ km$

The magnitude of the voltage induced in a conductor moving through a stationary magnetic field depends on the _______ and the __

Virty [35]

The correct answer is: Option (D) length, speed

Explanation:

According to Faraday's Law of Induction:

ξ = Blv

Where,

ξ = Emf Induced

B = Magnetic Induction

l = Length of the conductor

v = Speed of the conductor.

As you can see that ξ (Emf/voltage induction) is directly proportional to the length and the speed of the conductor. Therefore, the correct answer will be Option (D) Length, Speed
