Light is consist of different spectrum of colors called wave lengths. The colors that visible to the naked eye are known as Red, Orange, Yellow, Green, Blue, Indigo, and Violet. These colors are arranged from shortest to longest. The color red that appeared from the other side of the tank signifies that the wavelength that can only pass through the material is red, which is the shortest. Other wavelengths are dispersed into the molecules of the glass, hence it cannot be seen through the other side.

According to the law of conservation of energy, the total amount of energy in the universe does not change, but remains constant
Evgen [1.6K]
<span>The statement : According to the law of conservation of energy, the total amount of energy in the universe does not change, but remains constant - is TRUE. The main point which led me to decide is that our universe is the example of a closed system which means there's nothing inside. Hope you will agree with my opinion.

What impulse results if the force acting on an object is described by the force-time graph shown?
Hoochie [10]
The correct answer to this question is "2.1 kgm/s." The impulse results if the force acting on an object that is described by the force-time graph shown is that 2.1 kgm/s. Based on the graph, it shows like a plateau with the flat at the force of 2.1 N.

An ac series circuit contains a 20 ohm resistor, a capacitor of 0.75 micro farad, and an inductor of 120 mH. What frequency shou
Blababa [14]

Answer:

530.5 Hz

Explanation:

Given :

C=0.75 micro

L=120 mH

Reactance capacitor can be determined by

=\frac{1}{ wC}

where c =capacitor

= \frac{1}{w*0.75*10^-6}

Reactance inductor can be determined by

= w*L\\ = w*120*10^-3

As they are in series so ,

\frac{1}{w*0.75*10^-6}  =w*120*10^-3

On solving these value we get

w=3333.33

As we know that

f = \frac{w}{2*3.14} =

530.5 Hz
