The law of physics that this scenario would violate is the law of conservation of energy.

The law of conservation of energy states that energy possessed by an object or physical body can neither be created nor destroyed but can only be transformed from one form to another.

This ultimately implies that, the energy possessed by the rock at the beginning must be equal to the energy possessed by the rock at the end in accordance with the law of conservation of energy.

Decreased asthma and allergies symptoms.

Improved skin appearance.

Helps digestion.

Psychological and emotional stabilizer.

Better mood and normalized sleep patterns.

Reduce chances of lung, heart, and arterial diseases.

Negative Outcome :

According to the EPA, when we are exposed to high levels of hazardous air pollutants for an extended period of time .

We face a greater risk of suffering serious health effects, including respiratory diseases, neurological disorders, reduced fertility, damage to our immune system, and increased risks of getting cancer.

One of the health hazards that suprised me is that outdoor pollution is associated with hearth attacks. I know that outdoor pollution causes lung problems whether that's asthma attacks or bronchitis, but I didn't know about heart attacks. Apparently, air pollution can trigger heart attacks, stroke, and irregular heart rhythms. People who are already at risk for these conditions are more likely to have any of those. Air pollution causes damage to the inside walls of your blood vessels, causing them to become narrower and harder. Along with that, there are many different positives and negatives that came from the Clean Air Act some of which are more of these one that I explained on the top.

A summary paragraph evaluating the Clean Air Act in terms of cost and effectiveness given below.

The contamination of air or water or land by the human waste or chemicals is called as pollution.

Positive Outcomes are -

Negative Outcome is -

As indicated by the EPA, when we are presented to elevated degrees of perilous air poisons for a lengthy timeframe .

We face a more serious gamble of experiencing serious wellbeing impacts, including respiratory sicknesses, neurological issues, decreased fruitfulness, harm to our insusceptible framework, and expanded dangers of getting malignant growth.

The outside contamination is related with hearth assaults. Open air contamination causes lung issues like asthma assaults or bronchitis . Air contamination can set off coronary episodes, stroke, and sporadic heart rhythms. Air contamination makes harm within walls of your veins, making them become smaller and harder.

By applying the correspondent change of scale, we will see that Earth should be placed 214.8m away from the scale sun.

The real radius of the Sun is:

R = 696,340 km

And the radius of the scale Sun is 1m, then we have the relation:

1m = 696,340 km

1 = (1m/696,340 km)

Now, the real distance between the Sun and Earth is:

d = 149,600,000 km

If we apply the change of scale we have above, we will get:

d =  149,600,000 km*(1m/696,340 km) = 214.8m

So the Earth should be placed at 214.8m of the ball that represents the sun.

Explanation:

r=1.2, Period(T) = 9s

a) Speed(V) = ωr

ω = 2 x Pi(3.142) x frequency

frequency = 1/period

therefore; the frequency will be 1/9 = 0.1Hz

Therefore Speed(V) = 2 x 3.142 x 0.1 x 1.2=0.75m/s

C) Centripetal and centrifugal forces are the forces experienced by rotating objects. The centripetal force keeps an object moving in a circle and is always pointed toward the center of that circle. For instance, the gravitational force of the sun is a centripetal force that keeps the Earth orbiting around it. Its direction is always orthogonal to the motion of the body and towards the fixed point of the instantaneous center of curvature of the path.

Base on the experiment, we can deduce that the working principle of most electric generators is based on spinning a permanent magnet near coils of wounded wire.

Faraday's law of electromagnetism states that the negative rate of change of time (Δt) of the flux of the magnetic field (∅) through a surface is directly proportional to the flux (∅) of the electric field through a surface that has the loop as its boundary.

Electric generators are primarily designed and developed to use the properties of electromagnetism to convert kinetic energy (KE) that is possessed due to motion, into electrical energy. Thus, we can deduce that the mode of operation or working principle of most electric generators is based on spinning a permanent magnet near coils of wounded wire.

Answer:

Approximately [tex]1061\; {\rm Hz}[/tex] (rounded to the nearest whole number,) assuming that the speed of sound in the air is [tex]330\; {\rm m \cdot s^{-1}}[/tex].

Explanation:

Let [tex]v[/tex] denote the speed of this sound wave: [tex]v = 330\; {\rm m\cdot s^{-1}}[/tex] by assumption.

Let [tex]\Delta v[/tex] denote the speed at which the source (the bus) moves away from the observer (the cyclist.) In this question, [tex]\Delta v = 25\; {\rm m\cdot s^{-1}} - 5\; {\rm m\cdot s^{-1}} = 20\; {\rm m\cdot s^{-1}}[/tex].

Let [tex]d[/tex] denote the distance between the source (the bus) and the observer (the cyclist) when the first crest leaves the source. At a speed of [tex]v[/tex], it would take [tex]d / v[/tex] before the first crest arrive at the observer.

Let [tex]T[/tex] denote the period of this wave. If a crest of this wave leaves the source at [tex]t = 0[/tex], the very next one would leave at [tex]t = T[/tex]. Since the source is moving away from the observer at [tex]\Delta v[/tex], the distance between the two would have since increased from [tex]d[/tex] to [tex](d + \Delta v\times T)[/tex]. At a speed of [tex]v[/tex], this crest would now need [tex](d + \Delta v\times T) / v[/tex] to reach the observer.

In summary:

The time difference between the two crests is [tex]T[/tex] at the source. However, at the observer, this difference would have become:

[tex]\begin{aligned} &T + \frac{d + \Delta v\times T}{v} - \frac{d}{v} \\ =\; & T + \frac{\Delta v\times T}{v} \\ =\; & T\times \frac{v + \Delta v}{v}\end{aligned}[/tex].

Therefore, the ratio between the period at the source and at the observer would be:

[tex]\begin{aligned}\frac{T(\text{observer})}{T(\text{source})} &= \frac{\displaystyle T \times \frac{v + \Delta v}{v}}{T} \\ &= \frac{v + \Delta v}{v}\end{aligned}[/tex].

The frequency [tex]f[/tex] of a wave is equal to the reciprocal of its period [tex]T[/tex]. In other words, [tex]f = (1 / T)[/tex]. Therefore:

[tex]\begin{aligned}\frac{f(\text{observer})}{f(\text{source})} &= \frac{T(\text{source})}{T(\text{observer})} \\ &= \frac{v}{v + \Delta v}\end{aligned}[/tex].

Since [tex]f(\text{observer}) = 1000\; {\rm Hz}[/tex], [tex]\Delta v = 20\; {\rm m\cdot s^{-1}}[/tex], and [tex]v = 330\; {\rm m\cdot s^{-1}[/tex] by assumption:

[tex]\begin{aligned} & f(\text{source})\\ =\; & f(\text{observer}) \times \frac{v + \Delta v}{v} \\ =\; & 1000\; {\rm m\cdot s^{-1}} \times \frac{330\; {\rm m\cdot s^{-1}} + 30\; {\rm m\cdot s^{-1}}}{330\; {\rm m\cdot s^{-1}}} \\ \approx\; & 1061\; {\rm m\cdot s^{-1}}\end{aligned}[/tex].

The principle of cause and effect is applied in every life as is seen in damage caused to cells by exposure to large amounts of ultravoilet rays.

Cause and effect refers to the principle in which for every effect received or observed, an underlying cause is present.

Based on cause and effect;

Cells can repair small amounts of damage caused when a person is exposed to large amounts of gamma rays.

If a certain amount of exposure time in the sun is dangerous for adults, would result in a similar damage to a child.

A lot of sun exposure over time will cause an individual to develop a high risk of cell damage just as a shorter exposure time to X-rays gives the same risk.

Ultraviolet light can damage a cell especially with over 5 minutes of exposure to UVB light.

According to Gay - Lussac's law, you should heat it under conditions of constant volume.

An ideal gas obeys the equation of state PV = nRT at all pressures, volume and temperatute.

According to Boyle's law, the volume of a gas is inversely proportional to the pressure while temperature is constant.

Also, according to Gay - Lussac's law, increase in temperature is direclty proportional to increase in pressure while volume remains constant.

Suppose that you want to heat a gas so that its temperature will be as high as possible. According to Gay - Lussac's law, you should heat it under conditions of constant volume.
