Answer:
Explanation:
Given
Lowest four resonance frequencies are given with magnitude
50,100,150 and 200 Hz
The frequency of vibrating string is given by
where n=1,2,3 or ...n
L=Length of string
T=Tension
Mass per unit length
When string is clamped at mid-point
Effecting length becomes 
Thus new Frequency becomes
i.e. New frequency is double of old
so new lowest four resonant frequencies are 100,200,300 and 400 Hz
Eight electrons surrounding each non-hydrogen atom is the optimal electronic arrangement for covalent molecules because it is needed to achieve an octet structure and is necessary to fill both the s and p subshells of electrons.
<h3>What is Covalent bonding?</h3>
This is the type of bonding which involves the sharing of electrons between atoms of an element.
This is done to achieve an octet configuration thereby making them stable and less reactive thereby making it the most appropriate choice.

A the endocrine system does not fulfill its function
Bottom of the distillation flask
Explanation:
The solid in the mixture to be separate would be found at the bottom of the distillation flask.
Distillation is a separation technique for differentiating the components of mixtures based on the differences in their boiling points.
- Distillation is used to recover solvents from solution.
- The solutes are then left behind in the flask as the solvent boils out as vapor.
- The solution is boiled in a distillation flask to vaporize the solvent.
- The vapor is made to condense back into liquid by means of a condenser.
- The pure liquid called distillate is collected in the receiver.
- The solute which is the solid remains in the distillation flask
