A certain electric furnace consumes 24 kw when it is connected to a 240-v line. what is the resistance of the furnace?

weeeeeb [17]

One very handy electrical formula is

Power dissipated by a resistance = (Voltage)²/(resistance) .

24 kilowatts = (240 v)² / Resistance

Multiply each side by (Resistance):

(Resistance) x (24 kilowatts) = (240 v)²

Divide each side by (24 kilowatts):

Resistance = (240 v)² / (24,000 watts)

Resistance = (57,600 / 24,000) (volt² / volt · Amp)

Resistance = 2.4 (volt/Amp)

Resistance = 2.4 Ohms

The householder installs cavity wall insulation. What would happen to the time taken for the temperature to fall between points

scoundrel [369]

Answer:

the answers the correct one is: the time increases

Explanation:

When an insulating material is placed in the cavity of a wall the thermal conductivity of the system increases, therefore the temperature changes take longer.

P= dQ / dt = K A dT / dx

when placing insulation the value of k is less

When reviewing the answers the correct one is: the time increases

Assume you drink 250ml of soda out of a 1 liter soda bottle. how many liters are left?

charle [14.2K]

The correct answer is 0.75 liters.

<h3>Briefing:</h3>

One liter of soda produced 250 ml of beverage.

1 liter is equal to 1000 milliliters.

250 ml was consumed, or 250/1000 or 0.25 liter.

There was 1 - 0.25 liters of soda left

0.75 liter of soda was left and the correct answer is 0.75 liter.

<h3>What is a liter of water?</h3>

Four glasses of water make up one liter, to be precise.

Let us understand this using the following explanation. Despite the fact that there is no set standard size for glasses, their capacity varies. In contrast, we calculate that a liter holds 32 ounces and a glass holds 8 ounces of water.

<h3>How are liters measured?</h3>

Convert the object's dimensions into centimeters before performing the volume calculation in litres. Next, determine a shape's volume using the volume formula. For instance, you could use Volume = length times width times height to determine the volume of a cube, and the result would be in cubic centimetres.
