Experimental drinking frequently occurs as a result of taste aversion and social pressure.
What is peer pressure and why it is caused?Peer pressure is the influence or pressure that comes from one's peers. Peers are frequently referred to be members of the same social or age group. Peers often surround themselves with dimwitted or poor self-esteem individuals to do their bidding because they feel the need to be in charge.
Peer pressure has several root reasons, including the need to fit in, low self-esteem, fear of being rejected, and, most often, the desire to feel safe and secure among peers. Peer pressure has the worst results and might have severe impacts. Ages 12 to 19 are when peer pressure is most prevalent. Teenagers sometimes succumb to peer pressure and do things they wouldn't otherwise do.

Ernest rutherford was an important early researcher in nuclear physics. In one experiment, he observed that particles with a positive charge deflected when passing through a thin sheet of gold foil. What conclusion did rutherford make in this observation?.
Gold foil experiment
Ernst Rutherford conducted the Gold Foil Experiment in which α particles (doubly charged Helium Atoms) were bombarded on a thin gold foil. This experiment led to the discovery of the nucleus.
1) Most of the particles passed through undeflected
⇒ this meant that most of an atom is empty space
2) Some Alpha particles were deflected by some small angles
⇒ Since alpha particles are positively charged species , they can only be deflected if there are some positively charged atoms present that would repulse these particles.
3) A few ( about 1/20000 particles) bounced back
⇒There is a heavy mass of positively charged species in the atom , and since the alpha particles bounced back , this mass of positively charged species must have been highly dense.
Therefore, from these observations and inferences Rutherford concluded that most of an atom is empty space and there is a mass of positively charged particles in the center of the atom called the nucleus which contains protons. The electrons revolve around this nucleus at high speeds.
The mass of the atom is concentrated in the nucleus and is very small in size , making it highly dense.

A certain sample of the mineral galena (lead sulfide) weighs 12.4 g and has a volume of 1.64 cm3 . what is the density of galena?
The density of galena is 7.56 g/cm³.
We need to know about the density to solve this problem. Density can be described as how much the mass is in a volume unit. It can be written
ρ = m / V
where ρ is density, m is mass and V volume
From the question above, we know that
m = 12.4 g
V = 1.64 cm³
By substituting the given parameter, we can calculate the density
ρ = m / V
ρ = 12.4 / 1.64
ρ = 7.56 g/cm³
Hence, the density of galena is 7.56 g/cm³.

Neurons have a net negative charge at rest. This means that when they are active, they must have a positive charge. True or false?.
The statement is True.
Neurons have a net negative charge when it is at rest. This means that when they are well active, they must have a positive charge.
At rest, neurons have a net negative charge; the inside of neurons is approximately 70 millivolts more negative than the outside. When neurons are active, they must be positively charged in order to generate an action potential.
Neurons have a strong negative charge within them, as opposed to a positive charge outside. This is due to the presence of other molecules known as anions. They are negatively charged but far too large to escape through any available channel. They remain in place and give the cell a negative charge on the inside.
Because of an unequal distribution of positive ions across the membrane, the resting potential is negative; 3 Na+ is pumped out of the cell for every 2 K+ that enters, so the inside of the cell is less negative (less positive) than its surroundings.

explain why ???? and ???? can have magnitudes higher than the magnitude of the input source voltage when circuit 2 is at (or close to) resonance.
The reason why voltage across the inductor and capacitor can have higher magnitudes than that of input source voltage is because of electrical energy's oscillation between magnetic and electric field.
When current passes through an inductor a magnetic field is produced and the collapsing magnetic field produced by the inductor charges the capacitor. This process repeats itself causing the electrical energy to oscillate between magnetic and electric field. Because of this oscillation, at resonance, voltage across the inductor and capacitor can be greater than the input voltage.
For a RLC circuit,
[tex]V_{s}[/tex] = [tex]\sqrt[]{V_{R}^{2} + (V_{L} - V_{C})^{2} }[/tex]
where,
[tex]V_{R}[/tex] = Voltage across the Resistor
[tex]V_{L}[/tex] = Voltage across the inductor
[tex]V_{C}[/tex] = Voltage across the capacitor
At resonance,
[tex]V_{L}[/tex] = [tex]V_{C}[/tex]
Therefore, the reason why voltage across the inductor and capacitor can have higher magnitudes than that of input source voltage is because of electrical energy's oscillation between magnetic and electric field.

In the photoelectric effect, a beam of light impinges on metal, and it is observed that electrons are ejected from the metal in greater numbers as the intensity of light increases.
In physics, the photoelectric effect refers to a phenomenon in which the emission of charged particles takes place from a material or substance after absorbing electromagnetic radiation.
When light hits the surface of the material then electrons are released known as photoelectrons.
This phenomenon better explains the quantum nature of electrons and light.
Moreover, the study of the dual nature of wave particles has further expanded the scope, investigation, and understanding of the matter.
