Answer:
The temperature of cold reservoir should be 246.818 K for efficiency of 35%
Explanation:
In first case we have given efficiency of Carnot engine = 26 % = 0.26
Temperature of cold reservoir
We know that efficiency of Carnot engine is given by
For second Carnot engine efficiency is given as 35% = 0.35
And temperature of hot reservoir is same so
So
So the temperature of cold reservoir should be 246.818 K for efficiency of 35%
Answer:
The direction of propagation is west.
Explanation:
We know that electromagnetic waves (EM-waves) are transverse in nature. EM-waves containing electric field and magnetic field both are perpendicular to the each other ( E ⊥ B ).
Transverse waves : the direction of propagation is perpendicular to the direction of amplitude which we call transverse waves. eg : light waves, water waves, gravitational waves etc.
Here, in our case the direction of electric field is pointing upward to the plan of the screen and the direction of magnetic field is pointing north
∴ ×
Where direction of electric field,
direction of magnetic field,
direction of propagation at particular instant.
Above equation follows right hand rule. put your finger toward you (out of the screen) then curl to the north side then the thumb will give you the direction of the wave propagation ( west side )
In our case west direction is the direction of wave propagation.
