The static thrust of the turbojet engine mounted on a stationary test stand at sea level, with inlet and exit areas at 1.0 atm and 800 K respectively, is b.) Thrust 32680N.

To calculate the static thrust of the engine, we can use the ideal rocket equation:

Thrust = mass flow rate * exhaust velocity

The mass flow rate can be calculated using the equation:

mass flow rate = air density * inlet area * inlet velocity

The exhaust velocity can be approximated as the exit area times the exit velocity.

Given that the engine is mounted on a stationary test stand at sea level, we can assume the inlet velocity is zero. Additionally, we know the inlet and exit areas, as well as the atmospheric pressure at sea level.

By calculating the mass flow rate and the exhaust velocity using the provided information and plugging them into the ideal rocket equation, we arrive at the static thrust of approximately 32680N.

Answer:

The correct option is;

A. Circular

Explanation:

Some of the light that impinges on the surface are reflected and the rest are transmitted to a different medium

At the surface of the next medium also, some of the light are transmitted while the others are reflected and refracted through the first medium

The speed of light (and hence the wavelength and color) refracted through the thin film is changed as the distance the refracted light travels through the thin film is increased as we move away from the point directly in the front view to some distance as the reflected light path from those distance to the eye is increased due to their inclination giving them a different wavelength which are all equal at a radial distance from the eye hence forming a circular fringes.

There are three infrastructure projects wherein thermal expansion & contraction may be a problem are constructing roads, towers, and sidewalks.

The propensity of matter to alter structure, volume, or area in reaction to a temperature change is known as thermal expansion. The average molecular energy of a substance has a monotonic relationship with temperature. Heat makes molecules move more quickly & take up more space, which causes thermal expansion.

The expansion of heated air is the most obvious example. Heat helps the air expand, making it lighter than the air around it. This causes the hot air to be forced (upward), which causes steam and smoke to rise, warm air balloons to float, and so on.

The value of the shunt resistance Rs is calculated to be approximately (1.02 Ω).To convert a galvanometer into an ammeter with a maximum reading value of 500 mA, a shunt resistance (Rs) needs to be added.

The value of the shunt resistance can be calculated using the formula Rs = (RG * IMax) / (IMax - Max), where RG is the internal resistance of the galvanometer, IMax is the maximum deflection current of the galvanometer (15 mA), and Max is the desired maximum current reading of the ammeter (500 mA).

To convert a galvanometer into an ammeter, a shunt resistance is connected in parallel with the galvanometer.

The shunt resistance diverts a portion of the current, allowing the remaining current to flow through the galvanometer.

By choosing an appropriate value for the shunt resistance, the ammeter can be calibrated to measure higher currents.

In this case, the shunt resistance value (Rs) can be determined using the formula Rs = (RG * IMax) / (IMax - Max), where RG is the internal resistance of the galvanometer, IMax is the maximum deflection current of the galvanometer (15 mA), and Max is the desired maximum current reading of the ammeter (500 mA).

Substituting the given values,

we have Rs = (RG * 15 mA) / (15 mA - 500 mA). Simplifying further, Rs = (RG * 15 mA) / (-485 mA).

Rearranging the equation,

we get Rs = - RG * (15 mA / 485 mA). Since RG is given as (RG-59), we substitute it into the equation to obtain Rs = - (RG-59) * (15 mA / 485 mA).

The result of this calculation gives us the value of the shunt resistance Rs, which is approximately 1.02 Ω. Therefore, a shunt resistance of approximately 1.02 Ω should be added in parallel with the galvanometer to convert it into an ammeter with a maximum reading value of 500 mA.

If it is a true mixture, the mixing enthalpy is negligible, and there is no reaction or phase change, then you can do this using exclusively the temperatures of the individual compounds and their heat capacities. Any other process that takes place needs to be taken into account separately.

The solution can be found by understanding that we’re only using state variables. You can design any complicated process that starts with the starting situation and ends up at the ending situation, and the state variables will be the same. And sometimes a complicated process is easier to calculate than the simple one-step process, like here when mixing multiple components.

One way that will work is to start by bringing all compounds to the lowest temperature of either of the compounds. All but one of the compounds must be cooled down for this; make sure to calculate for each of the components how much energy is released. Now, mix all the components together. In the simplest situation sketched above you can calculate the heat capacity of the mixture by adding all the heat capacities of the components. Use this total heat capacity to calculate how much you can heat up the mixture using the energy you saved in cooling down the components earlier. This will be your desired end situation.

In case there are any phase changes or other processes in between, you need to take the energy needed for those into account too but in very similar ways.

The total work done by Happy Hogan is 0 joules because the package is being carried at a constant velocity and there is no change in kinetic energy. This is because work done is the product of force and displacement of an object in the direction of the force.

Hence, if there is no force applied or the object is not displaced in the direction of force then no work is done. The formula for work done is given as follows:

Work done = Force × displacement × cosθHere, cosθ = 1 because the force is applied in the direction of displacement. But in this case, there is no force applied to the package. Happy Hogan is just carrying the package at a constant velocity, hence, there is no change in the kinetic energy of the package.

Therefore, the total work done by Happy Hogan while carrying the package at a constant velocity across the room for 12 seconds is zero joules.

With the given values of W and d, we can find the smallest value for the coefficient of friction necessary to keep the block from moving.

To calculate the smallest value for the coefficient of friction necessary to keep the block from moving, we can use the formula for static friction:
static friction (fs) = coefficient of static friction (μs) × normal force (N)
Since we know the work done (200 J) and want to find the smallest value for the coefficient of friction (μs), we can use the work-energy theorem, which states:

Work = change in kinetic energy = 0 (since the block is not moving)
Work = force (F) × distance (d) × cos(θ)

200 J = μs × N × d × cos(θ)
Now, let's consider the forces acting on the block.

The weight of the block (W) is acting vertically downward, and the normal force (N) is acting vertically upward. In this case, the angle (θ) between the force and the direction of motion is 0 degrees,

so cos(θ) = 1.
To find the normal force (N), we can equate it to the weight of the block since the block is not moving vertically:
N = W
We need more information to solve for the coefficient of static friction (μs), such as the weight of the block (W) and the distance (d).

Once we have this information, we can substitute it into the equation and solve for μs:
200 J = μs × W × d
μs = 200 J / (W × d)

The chemical formula for dinitrogen tetroxide is C) N204.

Nitrogen that exists in its diatomic form, which is also known as molecular nitrogen or nitrogen gas, is referred to as dinitrogen. This form of nitrogen has two nitrogen atoms joined by a triple covalent bond, which satisfies the Lewis electron rules by having two lone, nonbonding electron pairs, one on each Nitrogen atom.

Whereas Dinitrogen tetroxide is colourless, Nitrogen dioxide is brown. As the temperature drops, the brown color's intensity falls. As a result, a drop in temperature results in a rise in Dinitrogen tetroxide. As temperature drops, equilibrium is pushed to the Dinitrogen tetroxide side.
