The property that she is testing is what is known as the boiling point. This describes the temperature (given a pressure) that a liquid begins to transition into the gas phase. By monitoring the production of bubbles (gas), she is investigating the boiling points of the two liquids. Hope this helps!

What would the circuit resistance be if a 7.5 Amp draw was present with the engine running and the charging system producing 15

AlladinOne [14]

Answer:

2 ohms

Explanation:

Hi there!

Ohm's law states that $V=IR$ where V is the voltage, I is the current and R is the resistance.

Plug in the given information (I=7.5, V=15) and solve for R

$V=IR\\15=(7.5)R$

Divide both sides by 7.5 to isolate R

$\frac{15}{7.5}= \frac{7.5R}{7.5} \\2=R$

Therefore, the circuit resistance would be 2 ohms.

I hope this helps!

A notebook sitting on a desk has 19 j of potential energy. What is the total mechanical energy of the notebook?

Alex17521 [72]

The total mechanical energy of the notebook is 19J.

Mechanical energy is the sum of potential energy and kinetic energy. It has no kinetic energy, because it's not moving. So its potential energy is all the mechanical energy it has.

A train moves at 300 km/h. How far will it go in 5 hours?

faust18 [17]

Answer:

1,500 km

Explanation:

300 km/h

300 kilometers PER HOUR

So you want to see how far it will go in 5 hours, all you need to do is multiply the kilometers by 5. Since we know that per hour it's 300 km.

300 * 5 = 1,500

The train moves at 1,500 km in 5 hours.

Hope this helped!
