Work is the product of force and displacement. whereas power is the rate of work done with respect to Time.
Answer:
Complete question:if a = 0.800 cm? (μ0 = 4π × 10-7 T · m/A)
Explanation:
Given:
Distance between plates = 0.8 cm
Distance from one plate = 1 mm
Current density 'J'= 16 A/m
Currents are flowing in opposite direction.
When current is flowing in opposite direction then magnetic field given as
By putting the values we get
Answer:
The value is
Explanation:
From the question we are told that
The number of turns is
The length is
The radius of the cross-section is
Generally the cross-sectional area is mathematically represented as
=>
=>
Generally the inductance is mathematically represented as
Here is the permeability of free space with value
=>
=>
Answer:
The surface tension is 0.0318 N/m and is sufficiently less than the surface tension of the water.
Solution:
As per the question:
Radius of an alveolus, R =
Gauge Pressure inside,
Blood Pressure outside,
Now,
Change in pressure,
Since the alveolus is considered to be a spherical shell
The surface tension can be calculated as:
And we know that the surface tension of water is 72.8 mN/m
Thus the surface tension of the alveolus is much lesser as compared to the surface tension of water.
Answer:
When two light waves traveling from opposite directions meet they experience wave interference. This happens when they are traveling along the same medium!
