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 .

Answer:
10m
Explanation:
The object distance and image distance is the same from the mirror. so the image is 5m behind the mirror.
5+5=10

From F = Miu(R)
Answer:
0.03924 m
Explanation:
Let g = 9.81 m/s2. Let x be the maximum distance that the spring will stretch. And let the potential energy reference point be at the the lower end where the spring is stretched to the maximum. Using mechanical energy conservation we have the following:
- At the bottom end where the spring is stretched to maximum: potential and kinetic energy is 0. Elastic energy is
- At the point where the weight is placed: potential energy is mgx, kinetic energy and elastic energy is 0 (because the spring is not stretched)
