Answer: 22,066N

Explanation:

By Newton's second Law of Motion, the force on an object is proprtional to the acceleration of the object. The proportionality constant is the mass of the object:

[tex]F=ma[/tex]

Plug in the mass and accleration of the system:

[tex]F=(1298kg)(17m/s^2)[/tex]

[tex]F=22,066N[/tex]

The units for force are Newtons, or equivalently kg*m/s^2.

The specific heat of the substance will be 0.129 J/g°C.

The amount of heat required to increase a substance's temperature by one degree Celsius is known as specific heat capacity.

Similarly, heat capacity is the relationship between the amount of energy delivered to a substance and the increase in temperature that results.

The given data in the problem is;

Q is the amount of energy necessary to raise the temperature = 3,000.0 j

M is the mass=  0.465 kg.

Δt is the time it takes to raise the temperature.=50°c

s stands for specific heat capacity=?

Mathematically specific heat capacity is given by;

[tex]\rm Q= MC \triangle t \\\\ C = \frac{Q}{M\triangle t} \\\\ C = \frac{3000}{0.465 \triangle 50} \\\\ C =129.0 J/Kg^0C \\\\ C= 0.129 J/g^0C[/tex]

Hence the specific heat of the substance will be 0.129 J/g°C.

Explanation:

Best answer of those given

Explanation:

a) Peroid = 1/frequency

F = 2 rev. per second = 2Hz

period = 1/2 = 0.5s

b) Tangential velocity(Vt) = ωr, where ω is thr angular velocity(2 * Pi(3.142) * f(frequency)) and r is the radius

Therefore; Vt = 2 * 3.142 * 2 * 0.65(65/100)

= 8.1692

= 8.2m/s

c) a = (V^2)/r where V is the velocity and r is the radius

a = (8.2^2)/0.65

a = 103m/s^2

Explanation:

The sound intensity level of 100 physics professors talking simultaneously is equal to 72 decibel.

Given the following data:

Sound intensity can be defined as a measure of the power of a sound wave per unit area. Thus, sound intensity is a quantity that can be used to measure the energy of sound and its unit of measurement is Watts per square meter.

Mathematically, sound intensity level is given by this formula:

[tex]\beta = 10 log(\frac{I}{I_{ref}} )[/tex]

Note: The reference value of sound intensity is equal to [tex]1.0 \times 10^{-12}\;W/m^2[/tex]

Thus, the sound intensity for one (1) professor is given by:

[tex]I_1 = 1.0 \times 10^{-12} \times 10^{5.2}\\\\I_1=1.585 \times 10^{-7}\;W/m^2[/tex]

For 100 professors, the sound intensity is:

[tex]I_{100} = 1.585 \times 10^{-7} \times 100\\\\I_{100}=1.585 \times 10^{-5}\;W/m^2[/tex]

Substituting the parameters into the formula, we have;

[tex]\beta = 10 log(\frac{1.585 \times 10^{-5}}{1.0 \times 10^{-12}})\\\\\beta = 10 log(15.58 \times 10^{6})\\\\\beta = 10 \times 7.2\\\\\beta =72\;dB[/tex]

Complete Question:

One physics professor talking produces a sound intensity level of 52 dB. It's a frightening idea, but what would be the sound intensity level of 100 physics professors talking simultaneously?

Answer:

72dB

Explanation:

The sound intensity level of one prof is given, that's your β1 (which is equal to 52dB).

Using the sound intensity level formula:

β1= 10log ([tex]\frac{I}{I_{o} }[/tex]) = 52 dB

*This will be useful later on [even if β1 is known]

Set up the formula for β2 (β2 is going to be the new sound intensity, the one for the 100 profs):

β2 = 10 log( [tex]\frac{ 100 I}{I_{o} }[/tex] )

*You need to multiply the intensity of one professor by 100 (because now there's more)

*do some algebra- pull out the 100

β2  = 10 log (100 [tex]\frac{I}{I_{o} }[/tex])

*use log laws

β2 = 10 ( log(100) + log ([tex]\frac{I}{I_{o} }[/tex]) )

*Now, isn't there a familiar part? Well, yes! The expression for β1!

β2 = 10log(100) + β1

β2 = 10log(100) + 52dB

*use your calculator

β2 = 73dB

^^^ that's your new sound intensity level

Speed, frequency and wavelength are interconnected to each other.

As a wavelength increases in size, its frequency and energy (E) decrease. As the frequency increases, the wavelength gets shorter. As the frequency decreases, the wavelength gets longer.

The wave speed is equal to the product of its frequency and wavelength, which shows the relationship between frequency and wavelength.

So we can conclude that speed, frequency and wavelength are interconnected to each other.

Positive Outcome :

Cleaner lungs.

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.

The torsional spring constant of the torsional oscillator (I = 0.25 kg · m² and T = 0.45 s) has a magnitude of 48.738 newton-meters.

The torsional spring constant indicates the resistance of the spring to an external moment. The torsional spring constant (κ), in newtons per meter, can be found by means of this formula in function of the period (T), in seconds and the moment of inertia (I), in kilograms per square meter:

[tex]\kappa = \frac{4\cdot \pi^{2}\cdot I}{T^{2}}[/tex]     (1)

If we know that I = 0.25 kg · m² and T = 0.45 s, then the torsional spring constant of the spring is:

[tex]\kappa = \frac{4\cdot \pi^{2}\cdot (0.25\,kg\cdot m^{2})}{(0.45\,s)^{2}}[/tex]

κ = 48.739 N · m

1) when we light a matchstick,the energy which got consumed in while rubbing the matchstick against the surface,turns into heat and hence ,it lights , therefore,the energy gets transferred from one type to another which proves the law of conservation of energy.

2) The coal gets burn and generate into electricity which further used by us for various purposes like lighting lamp and since the energy gets transferred from one source to another instead of ceasing, it proves the statement of conservation of energy.

3) As the pendulum swings in air , it continues to move from one point to another, changing potential energy to kinetic energy due to the motion that's taking place and unless an external force interferes, it's speed won't increase as at some point due to the friction by air will resist the movement resulting in decresement of kinetic energy and increased potential energy, thus ,at some point it will come to rest .

4) No ,it doesn't , because due to the force of friction,the disturbance in the movement of it ,takes place, making it stop at a specific point after some time.
