A plane electromagnetic wave of frequency 20 GHz moves in the positive y-axis direction such that its electric field is pointed along the z-axis. The amplitude of the electric field is 10 V/m. The start of time is chosen so that at t

When an electric field interacts with a magnetic field, electromagnetic waves are created. Therefore, they are referred to as "electromagnetic" waves. An electromagnetic wave's electric field and magnetic field are perpendicular to one another (at right angles).

An electromagnetic spectrum is a group of waves with similar characteristics to electromagnetic waves. All electromagnetic waves are transverse waves, capable of moving through a vacuum, and moving at the same speed in a vacuum, which is 300,000,000 times the speed of light.

Ksju [112]

Answer:

The value of heat transfer during the process Q = - 29.49 KJ

Explanation:

Given data

P_{1} = 50 \frac{lbf}{in^{2} } = 344.7 k pa

V_{1} = 4 ft^{3} = 0.113 m^{3}

T_{1} = 200 F = 366.4 K

T_{2} = 400 F = 477.6 K

Poly tropic index n = 1.2

gas constant for oxygen = 0.26 \frac{KJ}{kg K}

From ideal gas equation

P_{1} V_{1} = m R T_{1}

Put all the values in above equation we get

⇒ 344.7 × 0.113 = m × 0.26 × 366.4

⇒ m = 0.408 kg

Heat transfer in poly tropic process is given by

Q = \frac{\gamma - n}{( \gamma - 1)( n - 1)} [ {m R (T_{1} - T_{2}  ) ]

Put all the values in above formula we get

⇒ Q = \frac{1.4 - 1.2}{( 1.4 - 1)( 1.2 - 1)} [ {m R (T_{1} - T_{2}  ) ]

⇒ Q = 2.5 × 0.408 × 0.26 × ( 366.4 - 477.6 )

⇒ Q = - 29.49 KJ

This is the value of heat transfer during the process & negative sign shows that  heat is lost during the process.
