Answer:
-6N
Explanation:
The force to the east is acting in the positive x-direction therefore it is positive. The force to the east is in the negative x-direction therefore it is negative. The net force is just the sum of the two so 3-9=-6
If the charged particle moves in the magnetic field or electric field, then it experiences magnetic force or electric force because of its magnetic or electric properties.
<h3>What is magnetic field?</h3>
The magnetic field is the region of space where a charged object experiences magnetic force when it is moving.
When a charged particle such as an electron or proton moves inside a conductor, magnetic lines of force rotate around the particle. This relative motion causes the magnetic field to generate.
Thus, If the charged particle moves in the magnetic field or electric field, then it experiences magnetic force or electric force because of its magnetic or electric properties.

The following that are not true are E and D
Without specifics, the best element to conduct electricity would be copper.
Answer:
2234.63
Explanation:
Work done per cycle by the engine is calculated as;

#Since volume doesn't change in the isochoric steps, there is no work done, hence:

#For an isothermal change of state(ideal gas):

#for the expansion process:



Hence, the engine does 2234.63J per second.
