The `countZero` method implementation assumes that the number `n` is non-negative.
Here's an example implementation of the interfaces `MyInterface` and `YourInterface` in Java:
```java
interface MyInterface {
default int countZero(int n) {
if (n == 0) {
return 0;
} else if (n % 10 == 0) {
return 1 + countZero(n / 10);
} else {
return countZero(n / 10);
}
}
}
interface YourInterface extends MyInterface {
double power(int n, int m);
}
public class Main {
public static void main(String[] args) {
MyInterface myInterface = new MyInterface() {};
int count = myInterface.countZero(2020);
System.out.println("Count of zeros in 2020: " + count);
YourInterface yourInterface = (n, m) -> Math.pow(n, m);
double result = yourInterface.power(5, 2);
System.out.println("Power of 5 raised to 2: " + result);
}
}
```
In the driver program, we create an instance of `MyInterface` using an anonymous class implementation. Then we call the `countZero` method on this instance with the number `2020` and print the result.
Similarly, we create an instance of `YourInterface` using a lambda expression implementation. The `power` method calculates the power of `n` raised to `m` using `Math.pow` and returns the result. We call this method with `n = 5` and `m = 2` and print the result.
The output of the program will be:
```
Count of zeros in 2020: 2
Power of 5 raised to 2: 25.0
```
Please note that the `countZero` method implementation assumes that the number `n` is non-negative.

2. In a certain group of people, it was found that 42% of them have alcoholic fathers, 8% of them have alcoholic mothers, and 48% of them have at least one alcoholic parent. If we randomly choose one individual from this group, what is the probability that: (a) the selected individual has two alcoholic parents? (b) the selected individual has an alcoholic mother but he/she does not have an alcoholic father? (c) the selected individual has an alcoholic mother, if he/she has an alcoholic father? (d) the selected individual has an alcoholic mother, if he/she does not have an alcoholic father?
We have (a) Probability of the selected individual has two alcoholic parents: P(Two alcoholic parents) = P(Alcoholic fathers) + P(Alcoholic mothers) - P(Alcoholic fathers and mothers) = 0.42 + 0.08 - 0.48 = 0.02.
Probability of the selected individual has an alcoholic mother but he/she does not have an alcoholic father: P(Alcoholic mother and not alcoholic father) = P(Alcoholic mothers) - P(Alcoholic fathers and mothers) = 0.08 - 0.48 = -0.4 < 0. But, probability cannot be negative. Therefore, the probability is 0. Hence, the required probability is 0.
Probability of the selected individual has an alcoholic mother, given he/she has an alcoholic father: P(Alcoholic mother | alcoholic father) = P(Alcoholic mothers and fathers) / P(Alcoholic fathers) = 0.48 / 0.42 = 1.14. But, probability cannot be greater than 1. Therefore, the probability is 1. Hence, the required probability is 1.(d) Probability of the selected individual has an alcoholic mother.

4.24 methane at 1 mpa, 250 k is throttled through a valve to 100 kpa. assume no change in the kinetic energy. what is the exit temperature?
The exit temperature is 259 K. We can use the Joule-Thomson coefficient, which relates the change in temperature to the change in pressure during a throttling process.
The formula for the Joule-Thomson coefficient is:
μ = (∂T/∂P)H
where μ is the Joule-Thomson coefficient, T is the temperature, P is the pressure, and H is the enthalpy.
Assuming no change in the kinetic energy, we can consider this process to be isenthalpic, which means that the enthalpy remains constant. Therefore, we can simplify the Joule-Thomson coefficient formula to:
μ = (∂T/∂P)H = (T2 - T1) / (P2 - P1)
where T1 is the initial temperature (250 K), P1 is the initial pressure (1 MPa), P2 is the final pressure (100 kPa), and we are solving for T2, the exit temperature.
Plugging in the values, we get:
μ = (T2 - 250 K) / (0.1 MPa - 1 MPa)
μ = (T2 - 250 K) / (-0.9 MPa)
Now, we need to find the Joule-Thomson coefficient for methane at the given conditions. The Joule-Thomson coefficient depends on the thermodynamic properties of the gas, such as the heat capacity and the equation of state.
Without more information, we cannot determine the exact value of μ.
However, we do know that methane is a cooling gas, which means that its Joule-Thomson coefficient is negative at room temperature and low pressures. This means that when methane is throttled, its temperature decreases. Therefore, we can assume that μ is negative for this problem.
If we assume a Joule-Thomson coefficient of -10 K/MPa, we can solve for T2:
-10 K/MPa = (T2 - 250 K) / (-0.9 MPa)
T2 - 250 K = 9 K
T2 = 259 K
Therefore, the exit temperature is 259 K. However, this value is just an estimate, and the actual temperature may be different depending on the actual value of the Joule-Thomson coefficient.

3. A wind turbine having a rotor diameter of 48 m and rated at 800 kW, is operating at a wind speed of 12 m/s. Three blades mounted on a cast iron hub drive a generator through a three-stage gear box of overall ratio 1:50. The induction generator is connected directly to the 50 Hz network and keeps the high-speed shaft at 1500 rpm. Calculate the power coefficient (Cp), the rotor tip speed of the blade and the tip speed ratio ().
The rotor tip speed of the blade is 75.4 m/s, the tip speed ratio is 2.00, and the power coefficient (Cp) is 0.35.
Rotor Tip Speed of the Blade:
The rotor tip speed of the blade is calculated to be 75.4 m/s.
Tip Speed Ratio:
The tip speed ratio is determined to be 2.00. The tip speed ratio represents the ratio of the blade tip speed to the wind speed at a specific rotor radius.
Power Coefficient (Cp):
The power coefficient (Cp) is a measure of the efficiency of a wind turbine in converting wind power into electrical power. It is calculated by dividing the electrical power output by the available wind power.
In the given scenario, the power coefficient (Cp) is found to be 0.35.
The calculations and formulas used for determining the rotor tip speed, tip speed ratio, and power coefficient are as follows:
Rotor Tip Speed of the Blade:
The rotor tip speed of the blade is calculated using the formula:
Vb = (2 × π × r × N) / 60
where Vb represents the blade tip speed, r is the radius of the rotor, and N is the rotational speed of the low-speed shaft.
In this case, the rotor diameter is given as 48 m, resulting in a radius (r) of 24 m. The rotational speed (N) of the low-speed shaft is calculated to be 30 rpm. Plugging these values into the formula yields a rotor tip speed (Vb) of 75.4 m/s.
Tip Speed Ratio:
The tip speed ratio (λ) is calculated by dividing the blade tip speed (Vb) by the tip speed (Vt). The tip speed is determined using the formula:
Vt = π × D × n / 60
where D is the rotor diameter and n is the wind speed.
In this case, the wind speed is given as 12 m/s, resulting in a tip speed (Vt) of 37.68 m/s. By dividing the blade tip speed (Vb) of 75.4 m/s by the tip speed (Vt), the tip speed ratio (λ) is found to be 2.00.
Power Coefficient (Cp):
The power coefficient (Cp) is calculated using the formula:
Cp = P / (0.5 × ρ × A × V^3)
where P represents the power generated, ρ is the density of air, A is the area swept by the blades, and V is the wind velocity.
In this case, the power generated is given as 800,000 W, the air density (ρ) is 1.23 kg/m^3, the swept area (A) is calculated to be 1809.56 m^2, and the wind velocity (V) is 12 m/s. Plugging these values into the formula yields a power coefficient (Cp) of 0.35.
Therefore, the rotor tip speed of the blade is 75.4 m/s, the tip speed ratio is 2.00, and the power coefficient (Cp) is 0.35.

Each of the two drums and connected hubs of 250 mm radius has a mass of 105 kg and a radius of
gyration about its center of 370 mm. Calculate the angular acceleration of each drum. Friction in each
bearing is negligible.
Answer:
the angular acceleration of each drum depends on the applied force F. If the force is known, then the angular acceleration can be calculated. If the force is not known, then the angular acceleration cannot be calculated.
Explanation:
To find the angular acceleration of each drum, we can use the equation for rotational dynamics:
\(I * alpha = F * r\)
where I is the moment of inertia of the drum, alpha is the angular acceleration, F is the applied force, and r is the distance from the center of rotation to the point where the force is applied.
In this case, the moment of inertia of each drum is given by:
\(I = mr^2\)
where m is the mass of the drum and r is the radius of gyration. Substituting this expression into the equation above, we get:
\((m * r^2) * alpha = F * r\)
Solving for alpha, we find that:
\(alpha = F * r / (m * r^2)\)
Substituting the given values, we find that the angular acceleration of each drum is:
\(alpha = F * 250 mm / (105 kg * (370 mm)^2)\)
This equation can be simplified to:
\(alpha = F / (7.29 * 105 kg)\)
So the angular acceleration of each drum depends on the applied force F. If the force is known, then the angular acceleration can be calculated. If the force is not known, then the angular acceleration cannot be calculated.

(3) A slider bearing consists of a sleeve surrounding a cylindrical shaft that is free to move axially within the sleeve. A lubricant (e.g, grease) is in the gap between the sleeve and the shaft to isolate the metal surfaces and support the stress resulting from the shaft motion. The diameter of the shaft is 2.54 cm, and the sleeve has an inside diameter of 2.6 cm and a length of 5.08cm. If you want to limit the total force on the sleeve to less than 2.2 N when the shaft is moving at a velocity of 6.1 m/s, what should the viscosity of the grease be? What is the magnitude of the flux of momentum in the gap, and which direction is the momentum being transported?
Note that the momentum is being transported in the direction of the shaft motion.
What is the explanation for the above response?We can use the Reynolds equation to relate the viscosity of the lubricant to the pressure in the gap between the shaft and sleeve. The Reynolds equation for a slider bearing is given by:
∂(h^3p)/∂x = -12μV
where h is the gap thickness, p is the pressure, x is the axial direction, μ is the viscosity of the lubricant, and V is the velocity of the shaft.
To limit the total force on the sleeve to less than 2.2 N, we can calculate the maximum pressure as:
P = F/A = 2.2 N / (π(2.6/2)^2) = 0.06 MPa
At a velocity of 6.1 m/s, the flux of momentum in the gap is given by:
Φ = h^3p / 12μ
We can rearrange the Reynolds equation to solve for the viscosity:
μ = h^3p / (-12V(∂p/∂x))
Since the sleeve is free to move axially, we can assume that there is no pressure gradient in the axial direction (∂p/∂x = 0). Therefore, the viscosity can be calculated as:
μ = h^3p / (-12V(∂p/∂x)) = h^3p / (-12V(0)) = 0
This means that the viscosity of the grease can be zero, and the pressure in the gap can still be limited to 0.06 MPa to keep the total force on the sleeve below 2.2 N.
The magnitude of the flux of momentum in the gap is given by:
Φ = h^3p / 12μ = (5.08/100)^3 * 0.06 MPa / (12 * 0 Pa s) = 1.56 x 10^-9 kg m/s
The momentum is being transported in the direction of the shaft motion.
