Answer:
The answer is 10.857mJ
Explanation:
The energy stored in this solenoid is given by the below mentioned equation,
where L the inductance of this solenoid is given by the below mentioned equation,
Plugging this into the energy equation you obtain the equation for the total energy stored in the magnetic field of the solenoid, given by,
where is the permeability of free space which equals to . Plugging all the quantities into the above equation from the data in the question after converting to standard units. of meters instead of centimeters, we get for the energy stored in the coil,
Explanation:
An elastic band is hung on a hook and a mass is hung on the lower end of the band. When the mass is pulled downward and then released, it vibrates vertically. The equation of motion is given by :
Where
s is in centimeters
t is in seconds
Velocity of the particle,
Acceleration of the particle,
Hence, this is the required solution.
The amount of current flowing through the wire
The number of coils in the wire
The material in the core
Answer:
Angle of ray makes with the vertical is 62.1 degree
Explanation:
As per the ray diagram we know that the angle of incidence on oil brine interface will be given as
now by Snell'a law at that interface we have
now we will have
now this is the angle of incidence for oil air interface
so now again by Snell's law we will have
