Visible light has a range of wavelengths from about 400-750 nm. Which of these wavelengths is
most likely seen as the color red?

Answer:

They are all composed of gases.

Explanation:

The inner planets are mainly composed of types of rock. The surface and interior is rocky but the atmosphere is composed of gases. The outer planets happen to be composed mainly of gas, or in other terms, elements. The two primary elements that make up these planets are hydrogen and helium. Because the inner planets are made up of primarily, they have given the nickname the "Terrestial Planets" and the outer planets are called "Gas Giants" because of their gas (elements) composed atmospheres and overall interiors.

Answer: A: they are composed of gas

Explanation:

During the isobaric expansion;

The work done by a gas in an isolated expansion is the product of pressure and change in volume.

[tex]W = p\times \Delta V[/tex]

1 atm = 101325 Pa

2.4 cm³ = 2.4 × 10^-6 m³

4514.7 cm³ = 4514.7 × 10^-6 m³

[tex]W = 101325 Pa \times (4514.7\times 10^{-6} m^3 - 2.4\times10^{-6} m^3) = 457.2 J \\ [/tex]

Thus, work done by the gas is 457.2 J

Tje Heat absorbed by the water during vaporization process is calculated using the formul:

mass of water = density × volume

mass of water = 1 g/cm³ × 2.4 cm³ = 2 g = 0.002 kg

Q = 0.002 kg × 2.26 × 10⁶ J/kg

Q = 4520 J

Thus, heat absorbed by the water is 4520 J

The change in internal energy, ΔU of a system is given as the heat absorbed minus the work done by the system.

[tex]\Delta U = Q-W [/tex]

ΔU = 4520 J − 457.2 J = 4062.8 J

Therefore, the change in internal energy of a system is 4062.8 J.

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.

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

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.

if it was a love story you could call it ¨falling for you¨ hehe though since it's a project I'm guessing it's not a love story lol.

Explanation:

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

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.

5) 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 eventually come to rest .

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.

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.

area= pi (1.5x10^-3)^2

= 7.069m^2

convert power to W

1.9mW= 1.9x10^-3W
