A charged particle moving in a magnetic field experiences a force equal to:
Thus, the magnitude of the force that the proton experiences is given by:
The magnetic field is perpendicular to the proton's velocity, therefore, we have . Replacing the given values, we obtain:
Answer:
The electrical energy supplied is 0.233 kWh
Explanation:
Given :
Mass of air kg
Initial temperature 298 K
Final temperature 350 K
Heat loss kJ
From the first law of thermodynamics,
We know that internal energy is proportional to difference of temperature,
Now we need answer into kWh so ( 1 kWh = 3600 kJ ).
So we need to multiply ( )
kWh
kWh
Therefore, the electrical energy supplied 0.233 kWh
