Is this a complete question or is there a problem to match it? maybe goggle it?
Answer:
0.005 V
Explanation:
We are given that
Initial circumference of circular loop=C=165 cm
Rate of circumference,
Magnetic field,B=0.5 T
We have to find the induced emf at time t=9 s
We know that induced amf,E=
Area of circular coil,A=

Circumference of circular coil,C=



Radius of coil at time t=9 s


E=
Magnitude of induced emf=0.005 V
Answer:

Explanation:
The momentum of a body is defined as the product of its mass and its velocity at a given time. Therefore the change in the momentum of the ball is given by the difference between the final momentum and the initial momentum:

Answer:
a

b
Explanation:
From the question we are told that
The distance of separation is 
The is distance of the screen from the slit is 
The distance between the central bright fringe and either of the adjacent bright 
Generally the condition for constructive interference is

From the question we are told that small-angle approximation is valid here.
So 
=> 
=> 
Here n is the order of maxima and the value is n = 1 because we are considering the central bright fringe and either of the adjacent bright fringes
Generally the distance between the central bright fringe and either of the adjacent bright is mathematically represented as

From the question we are told that small-angle approximation is valid here.
So

=> 
So


substituting values



In the b part of the question we are considering the next set of bright fringe so n= 2
Hence

Answer:
the energy possessed by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors.
hope this helps
have a good day :)
