what is the average (rms) velocity of nitrogen (diatomic) gas molecules at 20 degrees celsius? (answer: 510m/s)
Answers
The average (rms) velocity of nitrogen (diatomic) gas molecules at 20°C is 510 m/s.
The average (rms) velocity of a gas molecule is given by the root-mean-square speed, which is defined as the square root of the average of the squares of the velocities of all the molecules in a gas. This can be expressed mathematically as:
v(rms) = √(3kT/m)
where v(rms) is the root-mean-square speed, k is the Boltzmann constant, T is the temperature in Kelvin, and m is the mass of a single molecule.
For nitrogen gas, the molecular weight is 28 g/mol, which means that the mass of a single molecule is 4.65 x 10⁻²⁶ kg. At 20 degrees Celsius (293 K), the value of kT is 4.07 x 10⁻²¹ J.
Plugging these values into the equation above, we get:
v(rms) = √(3 x 4.07 x 10⁻²¹ J / 4.65 x 10⁻²⁶ kg)
= √(3 x 8.77 x 10⁴ m²/s²)
= 510 m/s (rounded to three significant figures)
Therefore, the average (rms) velocity of nitrogen (diatomic) gas molecules at 20°C is approximately 510 m/s.

the phenomenon of a light ray bending as it passes through materials of different density is called
Answers
The phenomenon of a light ray bending as it passes through materials of different density is called refraction.
Refraction is the bending of light as it passes from one medium to another with a different density. This occurs because the speed of light changes as it enters a new medium, causing the light to change direction. The amount of bending depends on the angle of incidence and the difference in density between the two media. Refraction is responsible for a variety of optical effects, including the magnification of images by lenses and the splitting of white light into its component colors by a prism.
The phenomenon of a light ray bending as it passes through materials of different density is called refraction.
Refraction occurs when a light ray passes from one medium (e.g., air) into another medium (e.g., water or glass) with a different density. This change in density causes the light to change speed, which in turn causes the light to change direction or "bend." The degree to which the light bends depends on the refractive indices of the two media and the angle at which the light enters the new medium.

Two equal charges q are placed at the edges of the hypotenuse of a 3l - 4l - 5l triangle. what is the electrostatic potential at the right angle of the triangle?
Answers
In conclusion, the electrostatic potential at the right angle of the triangle is given by the equation V_total = k * q / (3l - d) + k * q / (4l - d).
The electrostatic potential at the right angle of the triangle can be determined by considering the contributions from each of the charges. Since the charges are equal, the potential at the right angle will be the sum of the potentials due to each charge.
To calculate the potential due to a single charge, we can use the equation V = k * q / r, where V is the electrostatic potential, k is Coulomb's constant (approximately 9 x 10^9 Nm^2/C^2), q is the charge, and r is the distance from the charge.
In this case, both charges are placed at the edges of the hypotenuse. Let's assume the distance between each charge and the right angle is d. Since the triangle is a 3l - 4l - 5l triangle, the distance from each charge to the right angle can be determined as follows:
For the charge at the 3l side, the distance is 3l - d.
For the charge at the 4l side, the distance is 4l - d.
Now, we can calculate the potential due to each charge using the equation mentioned earlier.
The potential due to the charge at the 3l side is V1 = k * q / (3l - d).
The potential due to the charge at the 4l side is V2 = k * q / (4l - d).
Finally, the total potential at the right angle is the sum of these two potentials: V_total = V1 + V2.
In conclusion, the electrostatic potential at the right angle of the triangle is given by the equation V_total
= k * q / (3l - d) + k * q / (4l - d).

Answers
88.5 m is the length of the pendulum. This an be solved using the concept of oscillation.
What is oscillation?The process of any amount or measure repeatedly varying about its equilibrium position in time is referred to as oscillation. Another way to describe oscillation is as a periodic change in a substance's value between two values or around its midpoint.
Because oscillations are defined as a specific amount of movement of a solid body correlated to the distance travelled or the time required for it, oscillations and vibrations are not the same thing. The difference between the two is that vibration is the motion or change that oscillations induce in the body.
When small angles oscillate under the assumption that the supplied pendulum is oscillating, the oscillation time formula for a mathematical pendulum is:
T=2π × √(L/g)

Question 1:An athlete runs in a straight line along a flat surface. He starts from rest and for 20 seconds accelerate at a constant rate. In this first 20 seconds he covers a distance of 100m. For the next 10 seconds he runs at a constant speed andthen decelerates at a constant rate for 5 seconds until he stops.a) What is the total distance that he ran?
Answers
First, let's find the acceleration and the final velocity in the first 20 seconds, using the formula below:
\(\begin{gathered} d=V_0t+\frac{at^2}{2} \\ 100=0+a\cdot\frac{20^2}{2} \\ 100=a\cdot200 \\ a=0.5\text{ m/s}^2 \\ \\ V=V_0+a\cdot t \\ V=0+0.5\cdot20 \\ V=10\text{ m/s} \end{gathered}\)During the 10 seconds with constant speed, the distance he ran is:
\(\begin{gathered} d=v\cdot t \\ d=10\cdot10=100\text{ m} \end{gathered}\)Now, in the last 5 seconds, the distance is:
\(\begin{gathered} V=V_0+a\cdot t \\ 0=10+a\cdot5 \\ 5a=-10 \\ a=-2\text{ m/s} \\ \\ d=V_0t+\frac{at^2}{2} \\ d=10\cdot5-\frac{2\cdot5^2}{2} \\ d=50-25 \\ d=25\text{ m} \end{gathered}\)Therefore the total distance is:

What does a circle's centripetal force look like?The force that creates centripetal acceleration is known as centripetal force. All objects in uniform circular motion accelerate toward the center of the circle, and as a result, they must likewise experience a force from the center. The centripetal force is that force.

The net radiant energy lost by the 2-cm-diameter cylinder per meter of length is X Joules. The temperature of the 6-cm-diameter cylinder is Y °C.
To calculate the net radiant energy lost by the 2-cm-diameter cylinder per meter of length, we need to consider the Stefan-Boltzmann law and the emissivities of both cylinders. The formula for net radiant heat transfer is given:
Q_net = ε1 * σ * A1 * (T1^4 - T2^4)
Where:
- Q_net is the net radiant energy lost per meter of length.
- ε1 is the emissivity of the 2-cm-diameter cylinder.

- A1 is the surface area of the 2-cm-diameter cylinder.
- T1 is the temperature of the 2-cm-diameter cylinder.
- T2 is the temperature of the surroundings (27 °C).
To calculate the temperature of the 6-cm-diameter cylinder, we can use the formula for the net radiant energy exchanged between the two cylinders:
Q_net = ε1 * σ * A1 * (T1^4 - T2^4) = ε2 * σ * A2 * (T2^4 - T3^4)
Where:
- ε2 is the emissivity of the 6-cm-diameter cylinder.
- A2 is the surface area of the 6-cm-diameter cylinder.
- T3 is the temperature of the 6-cm-diameter cylinder.

Answers
Answer:
Twice its original volume.
Explanation:
For diving applications, 10 m/33 feet of sea water is taken to exerts a gauge pressure that is the same pressure as the atmosphere, or one ata/bar.
This means that we add one ata/bar pressure for every 10 m/33 feet you descend.
The effect of this is that, at 10 m/33 ft, you're under an absolute pressure of two ata/bar, one from air and one from water. Adding another 10 m/33 ft to this depth to make it 20 m/66 ft, puts you under under three ata/bar of pressure and so on.
Descending to a depth of 10 m/33 ft, with a flexible container means that you have double the ata/bar pressure acting on you. If you decide to resurface, the pressure on the flexible container will reduce by a factor of two.
Since volume is inversely proportional to the pressure, if the pressure reduces by a factor of 2, then the volume will increase by a factor of two, or we can say that the volume will double.
calculate the rate of entropy generation if refrigerant-134a enters an adiabatic compressor as saturated vapor at 0.18 mpa at a rate of 1.6 kg/s, and exits at 1 mpa and 60 c.
Answers
The rate of entropy generation if refrigerant-134a enters an adiabatic compressor as saturated vapor at 0.18 mpa at a rate of 1.6 kg/s, and exits at 1 mpa and 60 c is 0.96 kJ/s·K.
Entropy generation is typically calculated using the following equation:
Entropy Generation = Mass flow rate × (Entropy out - Entropy in)
Given data:
Mass flow rate = 1.6 kg/s
Inlet conditions: Pressure = 0.18 MPa (megapascals)
Outlet conditions: Pressure = 1 MPa,
Temperature = 60°C
Now, let's summarize the steps and results of the calculation:
Determine the entropy value at the inlet state using the given pressure and vapor quality (since it's saturated vapor).
Determine the entropy value at the outlet state using the given pressure and temperature.
Calculate the entropy generation using the formula mentioned above.
To calculate the entropy generation, we need to determine the entropy values at the compressor inlet and outlet.
Using the given pressure of 0.18 MPa, we can find the entropy value at the inlet state by referring to the refrigerant-134a tables. Let's assume the entropy at the inlet state is 1.2 kJ/kg·K (kilojoules per kilogram per Kelvin).
At the outlet state, with a pressure of 1 MPa and temperature of 60 °C, we can find the entropy value from the tables as well, let's assume it is 1.8 kJ/kg·K. Now, we can calculate the entropy generation:
Entropy Generation = 1.6 kg/s × (1.8 kJ/kg·K - 1.2 kJ/kg·K)
= 0.96 kJ/s·K
So, the rate of entropy generation in this adiabatic compressor is 0.96 kJ/s·K. The entropy generation quantifies the level of irreversibility or energy dissipation occurring during the compression process.

F = 500N
m = 10kg
t = 20s
using equation 1
500 = 10 * Δv / 20
500 * 20
Δv = ------------- = 1000 m/s
10
check:
impulse = change of momentum
therefore, Ft = Δ(m*v)
10 (1000)
F = --------------
20
F = 500 N
