Answer:
A)
B)
C)
Explanation:
Given that:
- no. of turns i the coil,  
- area of the coil,  
- time interval of rotation,  
- intensity of magnetic field,  
(A)
Initially the coil area is perpendicular to the magnetic field.
So, magnetic flux is given as:
 ..................................(1)
..................................(1)
  is the angle between the area vector and the magnetic field lines. Area vector is always perpendicular to the area given. In this case area vector is parallel to the magnetic field.
 is the angle between the area vector and the magnetic field lines. Area vector is always perpendicular to the area given. In this case area vector is parallel to the magnetic field.


(B)
In this case the plane area is parallel to the magnetic field i.e. the area vector is perpendicular to the magnetic field.
∴  
From eq. (1)


(C)
According to the Faraday's Law we have:

rgvdghrryyrfgtr was the other monkey that I have to do with my best pet peeve for the rest and neon scooter is my friend is giving her the money for your cuz to be a good offer tho it was a great idea for a while and then she said yes and she is a great person ever and she was madly happy I have to go soon to be honest with me if she wants me back to my base or not but she wasnt it to be honest with her but 
 
        
             
        
        
        
W = F * s
Here, F = 50 N
s = 15 m
Substitute their values, 
W = 50 * 15
W = 750 J
In short, Your Answer would be 750 Joules
Hope this helps!
        
             
        
        
        
Recreational boaters have a role in keeping the waterways safe and secure. Violators of the restrictions can expect a quick and severe response. The operator should not approach within yards and slow to minimum speed within 500 yards of any of united states naval vessel. If the vessel need to pass within 100 yards of a united states naval vessel for safe passage, must contact the united states naval vessel or the united states coast guard escort vessel on VHF-FM channel 16. In addition,
•	The operator must perceive and avoid all security areas.
• Avoid commercial port operation areas particularly those that include military cruise line or petroleum amenities. 
•	The operator must perceive and avoid other controlled areas near dams, power plants, etc. 
•	The operator of the vessel must not discontinue or anchor underneath bridges or in the channel. 
        
                    
             
        
        
        
a). for velocity, you must have a number, a unit, and a direction. 
Yes.  This one isn't bad.  The 'number' and the 'unit' are the speed.
b). the si units for velocity are miles per hour. 
No.  That's silly.  
'miles' is not an SI unit, and 'miles per hour' 
is only a speed, not a velocity.  
c). the symbol for velocity is .
You can use any symbol you want for velocity, as long as 
you make its meaning very clear, so that everybody knows 
what symbol you're using for velocity. 
But this choice-c is still wrong, because either it's incomplete,
or else it's using 'space' for velocity, which is a very poor symbol.
d). to calculate velocity, divide the displacement by time.
Yes, that's OK, but you have to remember that the displacement 
has a direction, and so does the velocity.
