Answer and Explanation :
The opposition of the flow of alternating current produced by a magnetic field is called inductive reactance it is denoted by 
, The value of the inductive reactance depends on the value of inductance. The good thing about inductive reactance is that it is not responsible for the power loss as resistance is responsible for the power loss
The normal force is the supporting force that is exerted on an object that is in contact with another stable object.
Answer: Option C
<u>Explanation:
</u>
Normal force is forward or upward pushing force acting on an object. Mostly the normal force acts as supporting force exerted on the object by the neighbouring stable object with which the object in question is in contact. So normal force falls under the category of contact forces.
Generally, normal force will be acting to support the weight of any object placed on another object. The best examples of normal forces are the weight of the book supported by table or by the pushing force of the wall on the person leaning on the wall.
Answer:
50 j
Explanation:
W=Force*distance
W=10N*5M
W=50 NM
n*m = joules so you can say 50joules
