Answer:
Explanation:
work done by force exerted by canon = force x displacement
= 40 x 1.7 = 68 N
This energy would have been added to the potato .
Increase in potential energy of potato = mgh
= mg sin 35 x 1.7 = 2 x 9.8 x sin 35 x 1.7 = 19.11 J
Increase in kinetic energy = 68 - 19.11
= 48.89 J

Answer:
176.22 nm
Explanation:
= Index of refraction of oil = 1.64
= Wavelength of the light = 578 nm
= minimum thickness of the oil
For destructive interference, we have
For minimum thickness, m = 1
Answer:
The correct option is B
Explanation:
Although, it is common knowledge that in an electric field, unlike charges attract and like charges repel. However, to build up an electric potential, a positive charge is brought close to another positive charge - this causes work done to be changed to electric potential energy and stored in the electric field.
It should however be noted that when a negative charge is moved away from a positive charge, the negative charge gains electric potential energy.
