Answer:

There are 7 types of residential circuits.

Explanation:

Resendential Circuits means circuits used while wiring residential buildings. There are 6 different types of resedential wirings. Outlet Circuit, Lighting Circuit, Room Circuit, Special Circuit, 240 Volt Circuit, GFCI Circuit, and AFCI Circuit.

All the basic circuits of resedential building are connected with an outlet circuit, and this type of circuit have 15 - 20 amps of pole breaker. Lightening Circuit is only for the wiring of lights in the complete resedential building, so that if anything goes wrong in lights, we could inspect that much only.

Sometimes, even there is a separate circuit for Rooms, and in resedential building, each and every room have different circuit. There are many appliances which require very high wattage like furnaces, or refrigerator.

For them, special circuit is down and pole breaker is generally upto 30 apms. More heavy duty appliances are wired by 240 Volt Circuit, and GFCI and AFCI Circuits are for safety measures and to cutoff all the circuits if anything goes wrong.

The pressure gage on a 2.5-m^3 oxygen tank reads 500 kPa. Determine the amount of oxygen in the tank if the temperature is 28°C

s2008m [1.1K]

Answer:

19063.6051 g

Explanation:

Pressure = Atmospheric pressure + Gauge Pressure

Atmospheric pressure = 97 kPa

Gauge pressure = 500 kPa

Total pressure = 500 + 97 kPa = 597 kPa

Also, P (kPa) = 1/101.325 P(atm)

Pressure = 5.89193 atm

Volume = 2.5 m³ = 2500 L ( As m³ = 1000 L)

Temperature = 28 °C

The conversion of T( °C) to T(K) is shown below:

T(K) = T( °C) + 273.15

So,

T₁ = (28.2 + 273.15) K = 301.15 K

Using ideal gas equation as:

PV=nRT

where,

P is the pressure

V is the volume

n is the number of moles

T is the temperature

R is Gas constant having value = 0.0821 L.atm/K.mol

Applying the equation as:

5.89193 atm × 2500 L = n × 0.0821 L.atm/K.mol × 301.15 K

⇒n = 595.76 moles

Molar mass of oxygen gas = 31.9988 g/mol

Mass = Moles * Molar mass = 595.76 * 31.9988 g = 19063.6051 g

Explain the process of energy conversion by describing how energy was converted from the windmill design brief. Discuss the diff

cupoosta [38]

Answer:

Wind energy is converted to Mechanical energy which is then converted in to electrical energy

Explanation:

In a wind mill the following energy conversions take place

a) Wind energy is converted into Mechanical energy (rotation of rotor blades)

b) Mechanical energy is converted into electrical energy (by using electric motor)

This electrical energy is then used for transmission through electric lines.

1.0•10^-10 standard form

Drupady [299]

Answer:

$1.0 * 10^{-10} = 0.0000000001$

Explanation:

Given

$1.0 * 10^{-10}$

Required

Convert to standard form

$1.0 * 10^{-10}$

From laws of indices

$a^{-x} = \frac{1}{a^x}$

So, $1.0 * 10^{-10}$ is equivalent to

$1.0 * 10^{-10} = 1.0 * \frac{1}{10^{10}}$

$1.0 * 10^{-10} = 1.0 * \frac{1}{10}* \frac{1}{10}* \frac{1}{10}* \frac{1}{10}* \frac{1}{10}* \frac{1}{10}* \frac{1}{10}* \frac{1}{10}* \frac{1}{10}* \frac{1}{10}$

$1.0 * 10^{-10} = 1.0 * \frac{1}{10000000000}$

$1.0 * 10^{-10} = 1.0 * 0.0000000001$

$1.0 * 10^{-10} = 0.0000000001$

Hence, the standard form of $1.0 * 10^{-10}$ is $0.0000000001$
