Answer:
I = 578A
Explanation:
The magnitude of the peak value of the induced current flowing in a coild is given by


Where 
I= current
N = Number of loops
 angular velocity
 angular velocity
R= Resistance
B = Magnetic field
A = Area
Replacing our values we have that,


 
        
             
        
        
        
Answer:
True 
Explanation:
Electronegativity difference of less than 0.4 characterized covalent bonds. For two atoms with an electronegativity difference of between 0.4 and 2.0, a polar covalent bond is formed-one that is neither ionic nor totally covalent. 
 
        
                    
             
        
        
        
Answer:
Distance traveled during this acceleration will be 6950 m 
Explanation:
Wear have given maximum speed tat will be equal to final speed of the car        v = 278 m/sec
Constant acceleration 
As the car starts initially starts from rest so initial velocity of the car u = 0 m/sec
From third equation of motion 
Putting all values in equation 

s = 6950 m 
So distance traveled during this acceleration will be 6950 m 
 
        
             
        
        
        
Given mass= 1kg
Weight on earth = mg(gravity of earth) = 9.8N
weight on moon = mg(gravity of moon)= 1.62N
weight on outer space mg(gravity outer space = 0) = 0N
 
        
             
        
        
        
Explanation:
It is given that, the position of a particle as as function of time t is given by :

Let v is the velocity of the particle. Velocity of an object is given by :

![v=\dfrac{d[(8t+9)i+(2t^2-8)j+6tk]}{dt}](https://tex.z-dn.net/?f=v%3D%5Cdfrac%7Bd%5B%288t%2B9%29i%2B%282t%5E2-8%29j%2B6tk%5D%7D%7Bdt%7D)

So, the above equation is the velocity vector.
Let a is the acceleration of the particle. Acceleration of an object is given by :

![a=\dfrac{d[8i+4tj+6k]}{dt}](https://tex.z-dn.net/?f=a%3D%5Cdfrac%7Bd%5B8i%2B4tj%2B6k%5D%7D%7Bdt%7D)

At t = 0, 

Hence, this is the required solution.
