Which Of The Following Arguments Are Invalid And Which Are Valid? Prove Your Answer By Replacing Each (2024)

The java code can cause a compilation error running in a multithreading environment. One of the reason could be the variable "balance" is not declared as volatile, so there is no guarantee that the code will correctly set the balance and return the correct boolean value after a withdrawal.

Also, the java compiler could alerts an error when the return instruction is inside a cyclic structure and also when it is inside a conditional structure as it is in this case.

So, to fix errors, the return statement must be placed outside the conditional structure and use a variable instead of the boolean values. Below is a java code with the correct form.

Java code:

Consequently, it will take about 46,134.21 ft. lb. of labour to pump the entire pool's water out.

How would you calculate how much water is in a pool?

The volume in cubic feet is obtained by dividing that number by the depth. As there are 7.5 gallons in every cubic foot, multiplying the pool's cubic feet by 7.5 will give you the pool's volume in gallons.

V_sides = πr²h

= π(12 ft)²(5 ft)

= 2,262.74 ft³

V_water = πr²h

= π(8 ft)²(24 ft)

= 6,079.63 ft³

V = V_sides - V_water

= 2,262.74 ft³ - 6,079.63 ft³

= -3,816.89 ft³

W = Fd

F = mg

m = ρV

= 0.075 lb/ft³ × 3,816.89 ft³

= 286.29 lb

F = mg

= 286.29 lb × 32.2 ft/s²

= 9,226.84 ft·lb/s² = 9,226.84 N

W = Fd

= 9,226.84 ft·lb/s² × 5 ft

= 46,134.21 ft·lb

Explanation:

Torque:

The torque generated by the two blades is given by the formula T = F x r, where F is the aerodynamic force and r is the distance from the hub to the center of gravity of the blades. Therefore, the torque generated by the two blades is 1000N x 20m = 20000 Nm.

Power:

The power generated by the two blades is given by the formula P = T x w, where T is the torque and w is the angular velocity in radians per second. At 30 r/min, the angular velocity is w = 2π/60 x 30 = π/3 radians/sec. Therefore, the power generated by the two blades is 20000 Nm x π/3 = 66666.67 W.

The radiation heat transfer coefficient for the body is approximately [tex]1.77 x 10^{-8} W/(m^2 K^4)[/tex].

What is radiation?

Radiation is energy that travels through space at the speed of light from a source. This energy is associated with an electric and magnetic field, and it has wave-like properties.

The radiation heat transfer coefficient (hrad) can be calculated using the following formula:

hrad = Q / A∆[tex]T^4[/tex]

Where Q is the rate of radiation heat transfer, A is the surface area of the body, and ∆T is the temperature difference between the body and the surroundings raised to the fourth power.

In this case, we are given:

Q = 7.4 W

A = 1.2 m^2

T_body = 330 K

T_surroundings = 298 K

So, the temperature difference ∆T is:

∆T = T_body - T_surroundings = 330 K - 298 K = 32 K

Plugging in these values, we get:

hrad = 7.4 / (1.2 x [tex](32)^4[/tex]) = 1.77 x [tex]10^{-8 }W/(m^2 K^4)[/tex]

Note that the time taken to increase the speed is given as 7.5 seconds

What is the rationale for the above response?

To solve the problem, we need to convert the initial and final speeds from km/h to m/s, since the acceleration is given in m/s². We can use the conversion factor of 1 km/h = 0.27778 m/s.

Initial speed = 18 km/h = 18 x 0.27778 m/s = 5 m/s

Final speed = 72 km/h = 72 x 0.27778 m/s = 20 m/s

Now, we can use the following kinematic equation to find the time taken to increase the speed:

v = u + at

where,

u = initial speed = 5 m/s

v = final speed = 20 m/s

a = acceleration = 2 m/s²

t = time taken

Rearranging the equation, we get:

t = (v - u) / a

Substituting the values, we get:

t = (20 - 5) / 2

t = 7.5 seconds

Therefore, it takes 7.5 seconds for the vehicle to increase its speed from 18 km/h to 72 km/h under uniform acceleration of 2 m/s².

To calculate the deceleration of the vehicle, we first need to determine the initial velocity of the vehicle before it started to decelerate. We can use the kinetic energy of the vehicle to find its initial velocity as follows:

Kinetic energy = (1/2) * mass * velocity^2

800000 J = (1/2) * 820 kg * velocity^2

velocity = sqrt((2 * 800000 J) / (820 kg)) = 34.93 m/s

So the initial velocity of the vehicle was 34.93 m/s.

Next, we can use the formula for acceleration to find the deceleration of the vehicle:

acceleration = (final velocity - initial velocity) / time

The final velocity of the vehicle is 20 m/s, the initial velocity is 34.93 m/s, and the time taken to decelerate is 8 seconds. Therefore:

acceleration = (20 m/s - 34.93 m/s) / 8 s = -1.86625 m/s^2

The negative sign indicates that the vehicle is decelerating, or slowing down.

Finally, we can calculate the resistance force using the resistance to motion and the mass of the vehicle:

resistance force = resistance to motion * mass = 0.262 N/kg * 820 kg = 214.04 N

We can use this resistance force to check our answer, by calculating the deceleration from the resistance force and the mass of the vehicle:

deceleration = resistance force / mass = 214.04 N / 820 kg = 0.2617 m/s^2

This value is very close to the value we calculated earlier, which confirms that our answer is correct.

The Pascal distribution with parameters k and q represents the number of independent and identical Bernoulli trials needed to obtain k successes, where the probability of success in each trial is p=1-q. The probability mass function of this distribution is given by:

PX(x) = (x-1 choose k-1) * p^k * (1-p)^(x-k)

where x >= k and p = 1-q.

In this case, we are interested in the second largest value of PX(x) for X following a Pascal distribution with k=5 and q=0.92. We can find this value by first calculating the probabilities for all possible values of x that satisfy x>=5, and then selecting the second largest probability.

To simplify the calculations, we can use the complement of q as the probability of success in each trial, which is p=0.08. Then, the probability mass function becomes:

PX(x) = (x-1 choose 4) * 0.08^5 * 0.92^(x-5)

for x>=5.

To calculate the probabilities for different values of x, we can use a computer program or a spreadsheet. Here are the probabilities for x=5 to x=20:

xPX(x)

The Maximum Torque is calculated using the formula below. Divide 5252 by the maximum rotational speed, and then multiply the result by the maximum horsepower to determine the maximum torque.

T AB is equal to (pi/16)*tau max*d3.

T AB = (pi/16)*7.5 ksi*1.5 in3 = 131.20 kip-in (rounded to two decimal places)

The brass rod BC's torque is calculated as follows:

What are input devices?

An input device is any type οf hardware that takes data frοm οutside and sends it tο the machine tο prοduce an οutput.

An input device οften refers tο a piece οf hardware that transmits data tο a main device. The term an input device derives frοm the cοncept οf attaching hardware tο a primary device, like a cοmputer, tο cοnnect tο it and attempt tο cοntrοl it. User-input is prοvided by input devices, which are cοnnected peripherals.

What are οutput devices?

An οutput device is a device that shοws οr generates the οutput tο the wοrld. The system prοcesses the input data and generates the οutput data.

Sο accοrding tο the questiοn:

The input devices will be the push buttοn, and selectοr, and the οutput devices will be a sοlenοid and a pilοt lamp.

The length οf the perpendicular side x is apprοximately 4.62.

What is the right triangle?

A triangle in which οne οf the interiοr angles is 90° is called a right triangle. The lοngest side οf the right triangle, which is alsο the side οppοsite the right angle, is the hypοtenuse and the twο arms οf the right angle are the height and the base.

We can use the trigοnοmetric

ratiο οf the sine functiοn tο sοlve fοr x:

sin(35°) = οppοsite/hypοtenuse

sin(35°) = x/8

x = 8*sin(35°)

x ≈ 4.62 (rοunded tο twο decimal places)

Therefοre, the length οf the perpendicular side x is apprοximately 4.62
