Intensity of wave is defined as
here K = constant
A = amplitude
we can defined intensity by energy per unit area per unit time
So intensity is given by formula
So here we can say if` medium properties like density is uniform as well as frequency of wave will not change then energy of wave depends on intensity and intensity of wave directly depends on amplitude
So answer for the above question is Amplitude
Answer:
The distance is
Explanation:
From the question we are told that
The smallest shift is
Generally a grid unit is of an arcsec
This implies that 0.2 grid unit is
The maximum distance at which a star can be located and still have a measurable parallax is mathematically represented as
substituting values
Note
So
Answer:
83.3 Wb
Explanation:
The magnetic flux linkage through the coil is given by:
where
B is the magnetic field strength
A is the cross sectional area
N is the number of turns in the coil
is the angle between the direction of the field and the normal to the coil
In this problem:
B = 1.74 T
A = 0.133 m^2
N = 360
Therefore, the magnetic flux linkage is
