Asked Questions

What are the differences between progressive waves and stationary waves?

The differences between progressive waves and stationary waves are as listed below:

Progressive waves	Stationary waves
The disturbance travels forward.	The disturbances are confined to a particular region.
The amplitude of vibration of each particle is same.	The amplitude is zero at nodes and goes on increasing to become maximum at antinodes.
Energy is transferred forward along the waves.	No transfer of energy is in the medium.
No particles in the medium are at rest.	Particles...

What are the differences between transverse and longitudinal waves?

The differences between transverse and longitudinal waves are as listed below:

Transverse waves	Longitudinal waves
The particles of the medium vibrate in the direction perpendicular to the direction of wave propagation.	The particles of the medium vibrate parallel to the direction of wave propagation.
Alternate crests and trough are formed.	Alternate compression and rarefaction of the medium are formed.
These are formed in solids and over liquid surfaces.	These are formed in...

How can VL or VC be greater than V in a series LCR circuit?

At resonance, V_L and V_C are in antiphase (i.e. 180⁰ out of phase), therefore, their vector sum can be quite small— zero They are equal in magnitude at resonance.

So, they are greater than V in series LCR circuit.

What is Riemann's green?

Riemann's green is a green pigment ZnO.CoO, which is obtained by heating a mixture of zinc oxide and cobalt nitrate or by the reaction of cobalt nitrate with either $3 Z n (O H)_{2} Z n C O_{3}$ or zinc sulphate.

Define radiocarbon dating. Explain how the age of ancient dead animals and plants can be estimated by using radiocarbon dating.

Radioactive dating can be done by analyzing the fraction of carbon in organic material that is carbon14.

The ratio of carbon-14 to carbon-12 in the atmosphere has been roughly constant over thousands of years. A living plant or tree will be constantly exchanging carbon with the atmosphere and will have the same carbon ratio in its tissues.

When the plant dies, this exchange stops. Carbon-14 has a half-life of about 5730 years; it gradually decays away and becomes a smaller and smaller...

Write the truth table of the OR gate and the NAND gate. How the OR gate is drawn by using the NAND gate?

Considering, 1 as high input/output and 0 as low input/output

OR Gate (Truth Table)

First Input(A)	Second Input(B)	Output(Y)
1	1	1
1	0	1
0	1	1
0	0	0

NAND Gate (Truth Table)

First Input(A)	Second Input(B)	A.B(AND output)	NAND Output(Y)
1	1	1	0
0	1	0	1
0	0	0	1
1	0	0	1

As shown in the above figure, three NAND gates are...

Mention the condition of precipitation in terms of solubility product and ionic product.

When, Ionic Product > Solubility product, precipitation occurs.
