The total number of conductors, the kind of cable clamps being used, and any additional devices in the box must all be taken into account when determining the minimum cubic-inch capacity needed for the box.

In this case, you have two 12-2 AWG and two 14-2 AWG nonmetallic-sheathed cables, which means a total of 8 conductors.

The two 14-2 AWG conductors are spliced together and serve as a switch loop, so they count as 2 conductors.

The 12-2 AWG conductors are connected to a receptacle, which is 2 conductors. The two 14-2 AWG conductors are connected to a toggle switch, which is 2 conductors.

The minimum cubic-inch volume required for the box is determined by the National Electrical Code (NEC). According to the NEC, the minimum box volume for 8 conductors is 18 cubic inches.

The full-load current of a 25-horsepower, 480-volt, 3-phase, squirrel-cage induction motor is 12.7 A.

To calculate the full-load current of a 25 horsepower, 480-volt, 3-phase, squirrel-cage induction motor, you can use the formula:

Full-load current (I) = (Horsepower * 746) / (Voltage * 1.73 * Power factor)

where 1.73 is the square root of 3, which accounts for the 3-phase power and Power Factor is assumed to be 0.8

Plugging in the given values, we get:

I = (25 * 746) / (480 * 1.73 * 0.8)

I = 25746/(4801.73*0.8)

I = 25746/(4803.07)

I = 25*746/1478.4

I = 25*0.508

I = 12.7 A

Therefore, the full-load current of a 25-horsepower, 480-volt, 3-phase, squirrel-cage induction motor is 12.7 A.

It's worth noting that this is just an approximation and the current can vary depending on the motor design, the load and the power factor.

Ratio of g = 9:1

Explanation:

Given,

The ratio of the radius of planets = 1:3

let the mass of the planets be M

We can say that,

The radius of planet 1 = 1x

The radius of planet 2 = 3x

We know that g = GM/[tex]R^{2}[/tex]

g on first planet = GM / [tex]x^{2}[/tex] ,  g on second planet = GM/ 9[tex]x^{2}[/tex]

g on first planet: g on second planet  =  GM/[tex]x^{2}[/tex] * 9[tex]x^{2}[/tex] / GM

                                                                = 9:1

Answer:

L = E / M         energy input / water evaporated     (J/kg)

E = 60 J / s          60 J input in 1 sec

L = 60 J / (.006 / 60) kg = 600,000 J / kg

The specific latent heat of the vaporization of water is 6×10⁵ J/kg.

The amount of heat required to evaporate a certain mass of water can be calculated using the formula:

Q = ml

where Q is the heat required, m is the mass of water evaporated, and l is the specific latent heat of vaporization of water.

In this problem, we know that a heater with a power output of 60W evaporates 6x10⁻³ kg of boiling water in 60 seconds. We can calculate the amount of heat supplied by the heater using the formula:

Q = Pt

where P is the power of the heater and t is the time for which it is operating. Substituting the given values, we get:

Q = 60 W × 60 s

Q = 3600 J

We can now calculate the specific latent heat of the vaporization of water by rearranging the formula:

l = Q/m

Substituting the given values, we get:

l = 3600 J / (6×10⁻³kg)

l = 6×10⁵ J/kg

Therefore, the specific latent heat of the vaporization of water is equal to 6×10⁵J/kg.

However sun is the only reason behind every transformation of energy. For example wind energy generates from the movement of the wind. But wind is generated due to the pressure difference of two different placed, and this pressure difference is due to the temperature difference of that places. Which ultimately depends on the sun.

Mass is a better measure of the amount of matter than weight is because: C) mass is independent of location. Therefore, option C is the correct answer.

The mass of an object is a measure of how much object it contains. The kilogram (kg) is the fundamental SI ( International System of Units) unit of mass. On the other hand, weight is a unit of force equal to the gravitational pull on an object. The terms mass and weight are frequently confused. However, the main distinction between the two is their reliance on location. 

The weight of an object is dependent on its location, whereas its mass is independent of its location. For example, the gravitational force on the moon is approximately one-sixth than the gravitational force on Earth. As a result, an object will weigh six times more on Earth than it will on the moon. On the other hand, mass does not change with location because it is determined solely by the amount of matter present in an object.
