An atom consists of nucleus and electrons revolving around it.

Nucleus is filled with proton and neutron.

So atom consists of electron, proton and neutron.

Magnetic domain is not present in an atom.

Option A,Option B and Option C are present in an atom.

Option D is not present in an atom.

So Option D is the correct answer.

A flute player hears four beats per second when she compares her note to a 523 HzHz tuning fork (the note C). She can match the

laiz [17]

Answer:

527 Hz

Solution:

As per the question:

Beat frequency of the player, $\Delta f = 4\ beats/s$

Frequency of the tuning fork, f = 523 Hz

Now,

The initial frequency can be calculated as:

$\Delta f = f - f_{i}$

$f_{i} = f \pm \Delta f$

when

$f_{i} = f + \Delta f = 523 + 4 = 527 Hz$

when

$f_{i} = f - \Delta f = 523 - 4 = 519 Hz$

But we know that as the length of the flute increases the frequency decreases

Hence, the initial frequency must be 527 Hz

A composite is used specifically for a purpose which the two desired materials can provide by combining them.

Composites given better material integrity compared to their components.
A composite is produced in order to augment the properties of materials.
