Answer:
Electric flux
Explanation:
The electric flux measures the amount of electric field passing through a surface. For any closed surface, the electric field passing through it (electric flux) is given by Guass law. The mathematical relation between electric flux and the enclosed charge is known as Gauss law for the electric field. Electric flux may also be visualised as the amount of electric lines of force passing through an area.
Answer:
The correct option is momentum is conserved
Explanation:
A closed system is a system that is independent/free of external factors/force and does not exchange matter with its surrounding. Since a close system is free of external factors/force; <em>acceleration is constant in it, mass is conserved in it and there will be changes in velocities of objects in the closed system</em>.
This question actually seeks to test our knowledge of the law of momentum. The law of conservation of momentum states that the momentum of a closed system is conserved.
The pressure would increase as per Charle's Law, therefore the correct answer is option 4.
<h3>What is an ideal gas?</h3>
It is an imaginary gas for which the volume occupies by it is negligible, this gas does not exist in a practical situation and the concept of an ideal gas is only the theoretical one,
PV = nRT
As given in the problem statement we have to find out if the volume is held constant then what would happen to the gas if the temperature is increased,
For constant volume, the pressure of a gas is directly proportional to the temperature of the gas,
Thus, the pressure would increase as per Charle's Law, therefore the correct answer is option 4.

According to Newton's third law
- Ever action has a equal and opposite reaction.
So
- Hence if applied force is 8000N opposing force is also 8000N
As car is pushed forward so the opposing force is less than 8000N
Using the law of conservation of angular momentum, we have
<span>I1 w1 = I2 w2 </span>
<span>ie., m1r^2/2 x w1 = ( m1r^2/2 + m2r^2 ) w2 </span>
<span>ie., new angular velocity w2 = m1 w1 / ( m1+ 2m2) = 125 x 3.1 / ( 125 + 2 x39.5 ) </span>
<span>= 1.8995 = 1.9 rad /sec ( nearly )</span>
