<h2>Answer</h2>
Option A that is 8.8 × 10^3 m/s
<h2>Explanation</h2>
The magnetic field B is defined from the Lorentz Force Law, and specifically from the magnetic force on a moving charge. It says
Field-strength = BVqsinΔ
<h2>v = E/B </h2>
Since field are perpendicular so sin90 = 1
v = 4.6/10^4 / 5.2
v = 8846.15 m /s
The speed at which electrons pass through the selector without deflection = 8846.15 m /s
Answer:
The current would increase.
Explanation:
The current would increase. 10. The relationship between resistance and current in a circuit is that the greater the resistance the less the current and the greater the current the less the resistance is.
Answer:
the answer to the question is a reflector
The work done to push the refrigerator is 500 Nm.
Explanation:
Work done is the measure of force required to move any object from one point to another. So it is calculated as the product of force and displacement.
If the force increases the work done will increase and similarly, the increase in displacement increases the work done. So to push the refrigerator work should be done on the object and not by the object.
As the force is 100 N and the displacement is 5 m then, work done can be measured as
Work = Force × Displacement
Work = 100 × 5 = 500 Nm
So the work done to push the refrigerator is 500 Nm.
