Electrical shock is most likely to be fatal when the path of the current is through the heart.
Median plane - Sagittal plane through the midline of the body; divides the body or any of its parts into right and left halves.
The concept required to solve this problem is quantization of charge.
First the number of electrons will be calculated and then the total mass of the charge.
With these data it will be possible to calculate the percentage of load in the mass.
Here Q is the charge, n is the number of electrons and e is the charge on the electron
Replacing,
According to the quantization of charge the charge is defined as product of the number of electron and the charge on the electron
The total mass of the charge is
Here,
m = Mass of the charge
n = Number of electrons
= Mass of the electron
Replacing we have
Answer:
b) increase.
c) decrease.
d) Fringe is said to be a missing fringe when interference maxima overlap with diffraction minima.
Explanation:
a ) Young's interference is the interference phenomenon related to the light waves. Interference is the superposition of light waves . It proved the wave nature of light . Interference can be either constructive or destructive.
b) If the distance between the two slits increases, the number of fringes also increases. d sinθ = m λ. Here d is the slit width and m is the order of fringes. It shows that as d increases, m also increases.
c) Similarly, as d decreases , number of fringes decrease.
d) Fringe is said to be a missing fringe when interference maxima overlap with diffraction minima.
