If negligible velocity at inlet (C 1 ≈0), the velocity (C2) of steam (in m/s) at the nozzle exit is 447.21 m/s.

According to question:

The steady flow energy equation for steady flow devices

m (h1 + ((c1)2/2) + z1g) + Q = m (h2 + ((c2)2/2) + z2g) + Wcv

C1 = 0

Wcv = 0

z1 = z2

mh1 + Q = mh2 + m((C2)2/2)

m((C2)2/2) = m(h1-h2) + Q

0.1 × ((C2)2/2) × 10-3 = 0.1(2500-2350) -5

C2 = 447.21 m/s

Thus, the negligible velocity at inlet (C 1 ≈0), the velocity (C2) of steam (in m/s) at the nozzle exit is 447.21 m/s.

Hot objects contain more energy and emit photons at higher frequencies and shorter wavelengths compared to cool objects. Cool objects appear redder in color than hot objects.

Hot objects have a higher internal energy compared to cool objects. This higher energy is manifested in the form of increased thermal motion of particles within the object. As a result, hot objects emit more energy in the form of photons.

When it comes to the emission of photons, hot objects emit more photons at higher frequencies and shorter wavelengths. This is because the energy of individual photons is directly proportional to their frequency. Hotter objects have more energetic particles, leading to the emission of photons with higher frequencies and shorter wavelengths.

On the other hand, cool objects emit fewer photons and at lower frequencies and longer wavelengths. The lower energy of the particles in cool objects results in the emission of photons with lower frequencies and longer wavelengths.

In terms of color appearance, cool objects appear redder than hot objects. This is because cooler objects emit more photons in the red part of the electromagnetic spectrum, while hotter objects emit more photons in the blue part of the spectrum.

It would cost approximately 1.7 cents to charge batteries for a full day using this battery charger.

A battery stores chemical energy. Chemical energy is a form of potential energy that is stored in the chemical bonds between atoms and molecules. In a battery, this energy is stored in the form of chemicals that can be converted into electrical energy when the battery is used.

To calculate the cost of charging batteries for a full day, we first need to determine the amount of energy used by the battery charger in one day.

Since the power of the charger is 12 watts, we can calculate the energy used in one hour as:

12 watts × 1 hour = 12 watt-hours

To get the energy used in one day, we can multiply the energy used in one hour by the number of hours in a day:

12 watt-hours × 24 hours = 288 watt-hours

To convert watt-hours to kilowatt-hours (kWh), we need to divide by 1000:

288 watt-hours / 1000 = 0.288 kilowatt-hours

Finally, we can calculate the cost of using 0.288 kWh of energy at a rate of 6.0 cents per kWh:

0.288 kWh × $0.06/kWh = $0.01728

It would cost approximately $23.39 to leave a 28 W porch light on day and night for a year, considering the given cost per kilowatt-hour.

To calculate the cost of leaving a 28 W porch light on day and night for a year, we need to determine the total energy consumed by the light and then multiply it by the cost per kilowatt-hour (kWh).

First, we need to calculate the energy consumption in kilowatt-hours (kWh). Since the light is left on day and night, it will be operational for 24 hours a day.

Energy consumption per day = Power × Time = 28 W × 24 hours = 672 watt-hours (Wh)

To convert watt-hours to kilowatt-hours, divide by 1000:

Energy consumption per day = 672 Wh ÷ 1000 = 0.672 kWh

Now, we can calculate the energy consumption for a year (assuming 365 days):

Energy consumption per year = Energy consumption per day × 365 days = 0.672 kWh/day × 365 days = 245.28 kWh

Finally, we can determine the cost by multiplying the energy consumption by the cost per kilowatt-hour:

Cost = Energy consumption per year × Cost per kWh

     = 245.28 kWh × $0.095/kWh

Calculating this expression gives us the cost to leave the porch light on day and night for a year.

Cost = 245.28 kWh × $0.095/kWh ≈ $23.39

The electric field strengths E1 to E3 at distances 1.0 cm, 2.0 cm, and 3.0 cm from the glass rod along the line connecting the midpoints of the two rods can be calculated using the formula E = kQ / r

To find the electric field strengths E1 to E3 at distances 1.0 cm, 2.0 cm, and 3.0 cm from the glass rod along the line connecting the midpoints of the two rods, we can use the principle of superposition.

1. Calculate the electric field E1 at a distance of 1.0 cm from the glass rod:
  - We know that the electric field due to a charged rod is given by the equation E = kQ / r, where E is the electric field, k is the electrostatic constant (9 x 10⁹Nm²/C²), Q is the charge, and r is the distance.
  - Substitute the given values: Q = 7.00 nC (converted to 7.00 x 10⁻⁹ C) and r = 1.0 cm (converted to 1.0 x 10⁻² m) into the equation.
  - Calculate E1 using the given formula.

2. Calculate the electric field E2 at a distance of 2.0 cm from the glass rod:
  - Use the same equation, substituting Q = 7.00 x 10⁻⁹  C and r = 2.0 x 10⁻² m into the equation.
  - Calculate E2 using the given formula.

The speed ratio of particle A to particle B is approximately 2.83.

The kinetic energy of a particle is given by the formula KE = (1/2)mv^2, where m is the mass of the particle and v is its speed.

Given that particle A has half the mass and eight times the kinetic energy of particle B, we can write:

(1/2)mAvA^2 = 8(1/2)mBvB^2

Simplifying, we get:

mAvA^2 = 4mBvB^2

Dividing both sides by mBvB^2, we get:

(mA/mB)(vA/vB)^2 = 4

Since mA/mB = 1/2, we can substitute and solve for the speed ratio:

(1/2)(vA/vB)^2 = 4

vA/vB = sqrt(8)

vA/vB ≈ 2.83

Therefore, the speed ratio of particle A to particle B is approximately 2.83.

When resultant force acting on a body is zero then it is called as balanced force. motion of the body is not because of Balanced force. ex. when two persons pulling rope on both end with equal magnitude which cause them to be balanced force have 0 net force.

When resultant of all the forces is not equal to zero then we call it as Unbalanced forces. unbalanced force are responsible for the motion of the body.

Given,

Normal Force in upward direction = 17N

weight mg in downward direction = 17N

in this case both forces are in opposite direction. one is on positive y direction and other one is in negative y direction. Therefore net force acting on the computer desk is given by,

\(F^{2} _{net} = F^{2} _{1} + F^{2} _{2} + 2F _{1}F _{2}cos\alpha\).....1

where \(\alpha\) = angle between two forces.

\(\alpha\) = 180 \(cos\alpha\) = -1

\(F_{1} = F_{2}\) , 17N =17N

Analyze system dynamics and design compensator to achieve desired response by selecting compensator zero and canceling one pole of GHP(z).

To select a compensator zero to cancel one pole of GHP(z), we need to use the given angle condition:

Zzero - (pole(1) + Zpole(B)) = 180°

Here, Zzero represents the compensator zero, pole(1) represents the first pole of GHP(z), and Zpole(B) represents the compensator pole.

Let's proceed with the solution step by step:

1. First, we need to determine the value of Zzero. The angle condition states that Zzero = Zpole(1), which means the compensator zero is equal to the first pole of GHP(z).

2. Now, we need to find the value of Zpole(B). We can rewrite the angle condition as follows:

Zpole(B) = Zzero - pole(1) + 180°

Since we already know that Zzero = Zpole(1), we can substitute Zzero in the above equation:

Zpole(B) = Zpole(1) - pole(1) + 180°

Simplifying further:

Zpole(B) = 180°

Therefore, the value of Zpole(B) is 180°.

To summarize, we can select the compensator zero (Zzero) to cancel one pole of GHP(z) as Zpole(1), and the compensator pole (Zpole(B)) is determined to be 180° based on the given angle condition.
