Answer:
Explanation:
y1 = 16.2/2 = 8.1 cm
d = 1.22 lambda D/y1
d = 1.22 x 657 x 10^-9 x 23.7/0.081
d = 2.35 x 10^-4 m = 234.52 um
It is not possible to explain the interaction of the rod and pieces of paper as a gravitational interaction.
<h3>What is Gravitational interaction?</h3>
This is defined as the interaction between a particle or body resulting from their mass. This type of interaction is usually weak and occurs in all distances possible.
It is not gravitational interaction, because the rod attracts paper only against the gravitational force of the earth and there is no attraction between both bodies under a different condition.
This is therefore the reason why it is not possible to explain the interaction of the rod and pieces of paper as a gravitational interaction.

#SPJ1
Answer: A
Potential energy = 14.7 J
Explanation:
Given that the
Mass M = 5 kg
Height h = 0.3 m
Let us take acceleration due to gravity g = 9.81 m/s^2
Potential energy = mgh
Substitute all the parameters into the formula above
P.E = 5 × 9.81 × 0.3
P.E = 14.715 J
P.E = 14.7 J approximately
The correct option is therefore A
<h2>
reasons- instead of two,i got you five</h2>
1.Energy efficiency saves you money.
2.Energy efficiency improves the economy.
3.Energy efficiency is good for the environment.
4.Energy efficiency improves national security.
5.Energy efficiency enhances quality of life.
Electrical resistance is opposition to the flow of current in an electric circuit: resistance converts electrical energy to thermal energy, and in this regard is similar to mechanical friction. Resistances are said to dissipate electrical energy as heat.
