Here's the magic formula: 1 'volt' = 1 joule per coulomb .
Everything else is just arithmetic.
So Voltage = (energy) / (charge)
Voltage = (0.5 J) / (1.6 x 10⁻¹⁹)
= 3.125 x 10⁻¹⁸ .
A. During long jump athlete runs before taking the jump by doing so he provides himself a larger inertia.
<h3>
What is inertia?</h3>
Inertia is the reluctance of an object to stop moving once in motion or start moving when it is at rest.
When an athlete runs before taking the jump, he is trying to increase his inertia, that is his reluctance to stop, thereby increasing his forward motion or jump.
Thus, during long jump athlete runs before taking the jump by doing so he provides himself a larger inertia.

Answer:
n = 3
Solution:
Since, the slit used is same and hence slit distance 'x' will also be same.
Also, the wavelengths coincide, will also be same.
Using Bragg's eqn for both the wavelengths:
(1)
(2)
equate eqn (1) and (2):
n = 3
