Answer:

Explanation:
As we know that magnetic field due to torroid is given as

this is approximately constant magnetic field along the axis of the torroid
now the flux linked with one coil of the torroid is given as


now total flux of N number of coils is given as

now we know that self inductance is the property of coil in which flux of the coil will link with the current in the coil
So we know that


Answer:
The total mechanical energy of the clam when the seagull is 30.0 m above the ground is 97.8 Joules
Explanation:
Given:
Mass = 300 g
speed = 8.00 m/s
Height = 30.0 m
To Find:
Total mechanical energy of the clam = ?
Solution:
The total mechanical energy is the sum of the kinetic energy of the clam and its potential energy
Kinetic energy, 
Where m is the mass and v is the velocity
Potential energy,
where
m is the mass
g is the gravitational constant and h is the height
Then
Mechanical energy 
Converting g to kg we have
300 gram = 0.3 kg
On substituting the values,

Answer:
n = 1.56
Explanation:
The total reflection attempts occurs when a light beam passes from a medium with a higher index to a medium with a lower nest, at an angle where it occurs we can find them by the refractive relationship
n₁ sin θ₁ = n₂ sin θ₂
n1 = n2 / sin θ₁
For this relationship to be fulfilled, the liquid index must be greater than the air index divided by the sine of the critical angle
Let's use trigonometry to find angle
tan θ = y / x
θ = tan⁻¹ 7.2 / 8.6
θ = 39.94º
n₁ = 1 / sin 39.94
n = 1.56
This is the refractive index of the liquid
