The ideal gas law is represented by PV=nRT. As volume is held constant and the temperature increases, how would the pressure be
nydimaria [60]

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.

A charge −1.3 × 10−5 C is fixed on the x-axis at 7 m, and a charge 1 × 10−5 C is fixed on the y-axis at 4 m. Calculate the magni
wariber [46]

Answer:

6104 N/C.

Explanation:

Given:

k = 8.99 × 10^9 Nm2/C^2

Qx = 1.3 × 10^-5 C

rx = 7 m

Qy = 1 × 10−5 C

ry = 4 m

E = F/Q

= kQ/r^2

Ex = (8.99 × 10^9 × 1.3 × 10^−5) ÷ 7^2

= 2385.1 N/C.

Ey = (8.99 × 10^9 × 1.0 × 10^−5) ÷ 4^2

= 5618.75 N/C

Eo = sqrt(Ex^2 + Ey^2)

= sqrt(3.157 × 10^7 + 5.69 × 10^6)

= 6104 N/C.

Using the Left Hand Rule, if motion is down and the current is toward you, which way is the field?
Mama L [17]

In the left-hand rule, the field is represented by the forefinger and it is perpendicular to the motion.

<h3>Fleming’s Left-Hand Rule:</h3>

A force perpendicular to the field's direction and the direction of the current flow is experienced by a current-carrying conductor when it is exposed to an external magnetic field. According to Fleming's Left Hand Rule, if the thumb, forefinger, and middle finger are arranged in a straight line on the left hand, the thumb will point in the direction of the force experienced by the conductor, and the forefinger will point in the direction of the magnetic field, and the middle finger will point in the direction of the electric current. This rule is employed to determine the magnetic force's direction within an electric motor.

Fleming’s Left-Hand Rule are essential rules applicable in magnetism and electromagnetism. They were created by John Ambrose Fleming in the late 19th century as an easy method of determining the direction of motion in an electric motor.
