The correct answer among all the other choices is "None of the above." Electrons carry energy from a battery to a light bulb. The electron's potential energy will be converted into light energy. Thank you for posting your question. I hope this answer helped you. Let me know if you need more help.

Answer:

None of the above.

Explanation:

In a lightbulb, electrons at higher potential energy enter the lightbulb and give off that energy as they pass through the bulb. The number of electrons exiting and entering the bulb is the same. As electrons pass through the lightbulb, heat is produced due to the current, this makes the filament of the lightbulb to incandescence, and that is the light we see.

The answer is C. that liquids and gases both take the shape of their container.

Think of it this way, if you take an ice cube and put it in your glass, it will stay in its shape and stay that way until it melts. But if you put liquid or a gas into a glass, it will take the shape of the glass that it is put into.

A truck is traveling at 2.0 m/s. It slows to a stop at a constant rate over 3.00 s. How far does the car travel during those 3.0

earnstyle [38]

Answer:

During those 3.00 seconds before stopping, the car travels a distance of 6 m.

Explanation:

The simple rule of three is a tool that is used to quickly solve problems, where three pieces of information must be known, and one of them operates as an unknown to be known.

Two magnitudes are directly proportional if one magnitude increases the other also does it, and if the magnitude decreases the other in the same way.

Being a, b and c known data and x the unknown, the value that we want to know, the rule of three when the magnitudes are directly proportional is applied as follows:

a ⇒ b

c ⇒ x

So: $x=\frac{c*b}{a}$

In this case, knowing that a truck travels at 2 m/s, the rule of three applies as follows: if in 1 second the truck travels 2 m, in 3 seconds how much distance does it travel?

$distance=\frac{3 s*2 m}{1 s}$

distance= 6 m

During those 3.00 seconds before stopping, the car travels a distance of 6 m.

Gold has a density of 19300 kg/m³. Calculate the mass of 0.02 m³ of gold in kilograms.

hjlf

Answer:

Mass = 386 kg

Explanation:

Density = Mass / Volume

Mass = Density × Volume

Where D = 19300 kg/m³ , V = 0.02 m³

Putting the given in the above formula

Mass = 19300 × 0.02

Mass = 386 kg
