The gas has a final volume of 2.4L.
What is the text of Lussac's law?According to Gay Lussac's Law, a gas's pressure is precisely proportional to its Kelvin temperature when maintained at a low volume. The molecule of a gas receive more energy when heated, causing them to move more quickly. This results in increased pressure and more blows on the container's walls.
Briefing:
Given, Initial Volume of the sample = 3L
Initial temperature of the sample, T₁ = 200° C
= 200 + 273
= 473 K
Final temperature of the sample, T₂ = 100° C
= 100 + 273
= 373 K
By Gay-Lussac's Law is a variant of the general gas equation,
From the above relation,
[tex]\frac{V_{1} }{T_{1} } = \frac{V_{2} }{T_{2} }[/tex]
[tex]V_{2} = \frac{V_{1}*T_{2} }{T_{1} }[/tex]
Substituting values,
[tex]V_{2}[/tex]= (3x 373) / 473
= 1119/473
= 2.4L
Hence ,it is found that the final volume of the gas is 2.4L

7. what is the maximum angle of climb (steady velocity climb) for a turbojet powered aircraft with an (l/d)max equal to 10.5 and a gross weight of 8000 lb. if it is producing a thrust of 2000 lb.?
The maximum angle of climb for a turbojet powered aircraft is 8.97°.
Let us consider the velocity is steady.
T is thrust, W is weight, L for lift force, D for drag and θ is angle of climb
From the given information, we can write the below equations,
T = D + W sinθ -----(1)
L = W cosθ -----(2)
Given that, L/D = 10.5
D = L/10.5 -----(3)
Placing (3) in (1), we have
T = L/10.5 + W sinθ
T = (W cosθ)/10.5 + W sinθ
cosθ + 10.5 sinθ = T/W * 10.5
cosθ + 10.5 sinθ = (2000/8000) * 10.5
cosθ + 10.5 sinθ = 2.625
Solving the above equation, we get θ = 8.97°

The first bright diffraction fringe is 13.0 m away from the strong central maximum if the screen is 13.0 m away.
Calculate the wavelength of light.
The wavelength can be calculated using the formula, λ = d/n, where d is the distance between the slits (d = 0.050 mm) and n is the order of the diffraction fringe (n = 1).
Therefore, λ = 0.050 mm/1 = 0.050 mm.

How to find which statements are true about the angular momentumLet
I₁ = initial angular momentum of disk X = Ixω₀ where Ix = rotational inertia of disk x and ω₀ = angular velocity of disk y, I₂ = initial angular momentum of disk Y = 0 (since it is initally stationary) where I₃ = final angular momentum of disk x = Ixω and I₄ = final angular momentum of disk Y = Iyω where Iy = rotational inertia of disk y and ω = their common angular velocity after the collisionFrom the law of conservation of angular momentum, we have that
initial angular momentum equals final angular momentum
So, I₁ + I₂ = I₃ + I₄
Ixω₀ + 0 = Ixω + Iyω
Ixω₀ = Ixω + Iyω
From the above, we see that
Since I₄ > I₂ = 0,
The angular momentum of disk Y immediately after the collision is greater than the angular momentum of disk Y immediately before the collision.
Also, since I₁ + I₂ = I₃ + I₄,
The angular momentum of the disk X-disk Y system immediately after the collision is equal to the angular momentum of the system immediately before the collision.

All flight controls use the same basic lift principles as wings. When the pilot moves the controls, they produce lift of nose either up or down.
When the pilot pulls on the control column, the elevator moves up. This creates a wing-like curve on the surface that pulls the tail down. By moving the tail down, the nose of the aircraft rises.

Based on this model, how much of the energy will the tertiary consumers receive if the primary consumers have 3600 joules of energy?.
If the primary consumers have 3600 joules of energy, the tertiary consumers receive 36 joules energy.
What is 10 percent law of energy transfer?The ten percent law was proposed by Lindemann (1942) to explain how energy moves from one trophic level to the next. The law states that only around 10% of the organic substance that is transferred from one trophic level to the next of food is stored as flesh.
The rest is either lost in the transfer process or destroyed during breathing. Only 10% of the energy used by plants for primary production can be stored as net production that is available to herbivores. 10% of the energy in the food gets fixed into animal flesh when plants are eaten by animals, making it available for the next trophic level (carnivores). Only around 10% of the animal's energy is stored in its meat for the higher level when it is eaten by a predator.
So, If the primary consumers have 3600 joules of energy, the tertiary consumers receive 3600×10%×10% joules = 36 joules of energy.

A car travelling at 5.0 m/s starts to speed up. After 3.0 s its velocity has increased to 11 m/s. a) What is its acceleration? (Assume it to be uniform.) b) What distance does it travel while speeding up?
initially, the car is traveling at 5.0 m/s.
so, we know acceleration for changing velocity is :
a = (v-v[tex]_{o}[/tex])/t ..........(i)
where v is the final velocity
v[tex]_{o}[/tex] is the initial velocity
t is the time taken to change velocity
Now, as per the question :
initial velocity, v[tex]_{o}[/tex]=5.0 m/s
final velocity, v =11 m/s
time taken, t = 3 s
putting the values in equation (i),
a = ( 11-5 )/3
a = 2 m/s²
Therefore, a, after 3 s, is 2 m/s².
the centers of two slits of width a are a distance d apart. if the fourth minimum of the interference pattern occurs at the location of the first minimum of the diffraction pattern for light of wavelength λ, the ratio a/d is equal to:____.
centers of two slots of width an are separated by this amount. If the initial minimum of the diffraction peak of light of wavelength is where the fourth minimum of the interferometer is located, then the ratio a/d is equal to 2/7.
The wavelength, what is it?A waveform signal's wavelength is defined as the separation between two similar points (adjacent crests) in adjacent cycles as the signal travels through space or along a wire. This length in wireless systems is typically expressed in metres (m), centimeters (cm), or millimeters (mm) (mm).
What exactly are wavelengths and frequencies?The wavelength is indeed the distance that separates two wave crests, while troughs have the same wavelength. The number of oscillations which pass over a specific place in a second is known as the frequency and is expressed in seconds of cycles (Hz) (Hertz).
