Answer:

Explanation:
We have given number of turns N = 560
Inductance L = 8.9 mH 
Current through the coil = 7 mA
Inductance of the coil is given as 
Where N  is number of turns I is current and 
 is flux 
So

Answer:
The helicopter uses 35 gallons to fly for 5 hours.
Explanation:
The amount of gas that a helicopter uses for flying varies directly proportional to the number of hours spent flying.
g ∝ T
where g represents amount of gas and T time of flight.
Then,

The helicopter files 4 hours and uses 28 gallons of fuel.
Here, g₁= 28 gallons, T₁=4 hours
g₂=?, T₂=5 hours.


⇒28×5= g₂×4
⇒ g₂×4=28×5

 gallons
The helicopter uses 35 gallons to fly for 5 hours.
 
        
             
        
        
        
Acceleration is the rate at which an object changes its velocity. It defines how much the velocity is changing. The acceleration can be negative and positive. Negative acceleration is when the object slows down, while positive while the object goes faster.
