Which is the correct sequence of transfers in a typical coal fired power plant?

Answer:

The effective (rms) current when the circuit is in resonance is 6 A

Explanation:

Given;

resistance of the resistor, R = 20 ohms

capacitance of the capacitor, C = 0.75 microfarads

inductance of the inductor, L =  0.12 H

effective rms voltage, \(V_{rms}\) = 120

At resonance, the impedance Z = R, Since the capacitive reactance (Xc) is equal to inductive reactance (XL).

The effective (rms) current, = \(V_{rms}\) / R

                                              = 120 / 20

                                              = 6 A

Therefore, the effective (rms) current when the circuit is in resonance is 6 A

Answer:

60w

Explanation:

The power required is 30 Watt.

Let us recall that power is defined as the rate of doing work. Hence, we can write as follows;

Power = Work done/ time taken

Now;

work done =  Force × distance

Force = 30.0 N

Distance = 10.0 m

work done = 30.0 N × 10.0 m = 300 J

The power expended = 300 J/10.00 s = 30 Watt

Air masses from the tropics and the equator are warm as they form over lower latitudes. The major causes for moving air masses North America exists jet storm.

An air mass is a volume of air that in meteorology is identified by its temperature and humidity. Many hundreds or thousands of square miles are covered by air masses, which adjust to the properties of the land underneath them. Latitude and their continental or maritime source regions are used to categories them.

Warmer air masses are referred to as tropical, whilst colder air masses are referred to as polar or arctic. Superior and maritime air masses are moist, whereas continental and superior air masses are dry. Air masses with various densities are divided by weather fronts. Once an air mass has left its original location, nearby plants and bodies of water can quickly change the way it behaves. Classification systems address both the properties and modification of an air mass.

Air masses from the tropics and the equator are warm as they form over lower latitudes. They move poleward along the southern edge of the subtropical ridge and are drier and hotter than those that originate over seas. Trade air masses are another name for tropical maritime air masses. The Caribbean Sea, southern Gulf of Mexico, and tropical Atlantic Oceans, east of Florida via the Bahamas, are the origins of maritime tropical air masses that have an impact on the United States.

Monsoon air masses are moist and unstable. Rarely do dry superior air masses touch the ground. A trade wind inversion, which is a warmer and drier layer over the more moderately moist air mass below, is typically created over maritime tropical air masses when they are located above them.

The magnitude and direction of the electric field is equal to 3.45 x10^13 N/m and the direction in towards the negative charge.

To calculate the electric field of a point it is necessary to use the following expression:

                                             \(E = k\frac{Q}{d^{2}}\)

Thus, calculating the field formed by each charge we have:

                                    \(E = 9 \times 10^{9} \times \frac{8}{36\times 0.0001}\)

                                      \(E = 2\times 10^{13} V/m\)

                                   \(E = 9 \times 10^{9} \times \frac{5.8}{36\times 0.0001}\)

                                    \(E = 1.45 \times 10^{13} N/m\)

The direction of the electric field of the negative charge is towards the charge (attracted) and of the positive charge is repelled.

So, we can add the two values ​​of field found, since the two are directed towards the negative charge, so that :

                                       \(E = 2 \times 10^{13} + 1.45 \times 10^{13}\)

                                       \(E = 3.45 \times 10^{13} N/m\)

So, the magnitude of eletric field is equal to 3.45 x10^13 N/m and the direction in towards the negative charge.

Answer:

The input energy to  engine 2  is \(E_2 = 3807.7\ J\)

Explanation:

From the question we are told that

     The efficiency of engine one is  \(\eta_1 = 0.18\)

     The input energy required is \(E = 5500 \ J\)

       The efficiency of engine 2 is \(\eta_2 = 0.26\)

Generally the workdone by the engine 1  is mathematically represented as

       \(W_1 = E * \eta_1\)

=>     \(W_1 = 5500 * 0.18\)

=>     \(W _ 1= 990 \ J\)

Generally the workdone by engine 2  is mathematically represented as  

        \(W _2= E_1 * \eta_2\)

=>     \(W _2 = E_1 * 0.26\)

=>     \(W_2 =0.26E_1\)

From the question we are told that \(W_1 = W_2\)

So  

       \(990 =W_2 =0.26E_1\)

=>     \(E_2 = 3807.7\ J\)

Explanation:

We know the formula: Force = [mass( final velocity - initial velocity )] / time

using the formula:

83 = 0.45 (  1.3 - 0 ) / time

time = ( 0.45 * 1.3 )/ 83

time  = 0.585/83

time = 7.0 milliseconds

The time for the mallet in contact with the ball is 7 milliseconds.

To find the time , the given values are,

Mass = 0.45 kg

Force = 83 N

Final velocity = 1.3 m/s, Initial velocity = 0 m/s.

According to Newton's second law of motion, Force is equal to mass that is multiplied by the acceleration.

F = m.a

where, F - Force

m - Mass

a - Acceleration

Here,  Acceleration = ( Final velocity - Initial Velocity) / ( Time )

Acceleration can be defined as the change in velocity with respect to time.

Force = [mass( final velocity - initial velocity )] / time

Substituting the given values in the formula,

83 = 0.45 (  1.3 - 0 ) / Time

Time = ( 0.45 * 1.3 )/ 83

hydrogen

Atomic fusion occurs when 2 or more atoms combine to create a new element.

Helium

Before figuring out what elements create helium, we need to understand its properties. Helium is the second element on the periodic table. It has 2 protons and usually 2 electrons in the base state.

There are technically ions but base helium will have 2 electrons, especially because it is a noble gas.

Fusion

In most cases, including this one, when 2 atoms fuse together you can add their protons together to find the atomic number of the new element. Since helium only has 2 protons, the elements fused to form helium must both have 1 proton.

The element with 1 proton is hydrogen. So, 2 hydrogen atoms fuse to form helium.

Real World Applications

Fusion can be seen across the universe. One of the most common examples of hydrogen fusing to become helium is in stars. Due to the heat within stars, 2 hydrogen atoms can fuse together to create helium. This process also creates energy in the form of heat and light that the star is made of.

If the car continues to decelerate at this rate then the total distance of car is 324.91 meters.

When an object slows down, it undergoes deceleration, which is the opposite of acceleration. There are usually two ways that acceleration slows down. The first occurs when an object slows down by itself. Gravity, friction, or momentum loss could be to blame. The second is when the object is subjected to an external force, such as when a car driver applies the brakes or a pilot deploys the air brakes in an airplane. A journey that is both safe and successful requires deceleration, which is an essential component of movement.

                       d₁ = R × θ

                        = 0.42×73×2× π

                               = 192.6 m

Using 2nd kinematic equation for distance traveled in next 16 sec:

                              θ₁ = wi × t + (1/2)× α ×t²

             θ₁ = 39.69 × 16 + (1/2) × (-2.5) × 16²

                                 = 315.04 rad

                 d₂ = R× θ₁

                        = 0.42× 315.04

                               = 132.31 m

So total stopping distance = 192.6 + 132.31

                                            = 324.91 m

Therefore, the total distance is 324.91 m.

Answer:

Explanation:

Sure, I'd be happy to help you with the question!

Let's denote the input as x. According to the function machine, the input is multiplied by 6 and then 80 is subtracted from the result to obtain the output.

So, the function can be written as:

Output = (6 * x) - 80

Now, the problem states that the input is the same as the output. Therefore, we can set up the equation:

x = (6 * x) - 80

Let's solve this equation to find the value of x:

x = 6x - 80

Subtracting 6x from both sides, we get:

x - 6x = -80

Combining like terms, we have:

-5x = -80

Dividing both sides by -5, we find:

x = (-80) / (-5)

Simplifying the expression, we have:

x = 16

Therefore, the input (x) that results in the input being the same as the output is 16.

To work out these types of questions, it's important to carefully read the instructions and understand the operations being performed in the function machine. Then, you can set up an equation with the input and output, and solve for the unknown value. Always double-check your solution to ensure it satisfies the given conditions of the problem.

Answer:

16

Explanation:

(x*6) - 80 = x

Multiply the parentheses

6x - 80 = x
Add 80 to each side to get
6x = x + 80
Subtract x from both sides to get
5x = 80
Divide both sides by 5
x = 16
