5 0

Answer:

All of these answers are dependent upon the specific scenario, but here are some general answers.

1. An object with a greater height will have more potential energy.

2. Potential energy can be changed into kinetic energy as an object falls. It loses height (potential energy) and gains speed (kinetic energy).

3. Depends on what scenario your class had.

What causes gaps in the asteroid belt (known as Kirkwood Gaps)?
torisob [31]

Answer:

(b) Gravitational interactions with Jupiter

Explanation:

Gaps in the asteroid belt also known as Kirkwood Gaps are caused by the gravitational interaction between Jupiter and asteriods with Jupiter's orbital period. These Jupiter's orbital period occurs in a simple fraction, such as half, one-third, quarter etc.

Therefore, the correct option is "b" Gravitational interactions with Jupiter.

A housefly walking across a clean surface can accumulate a significant positive or negative charge. In one experiment, the large
Lisa [10]

Answer:

4.56*10^8 \text{    electrons.}

Explanation:

Since the fly accumulated a positive charge of +73pC, it must have lost an equal number of negative charge of -73pC to the surface (because the housefly was neutral to begin with).

Therefore, to answer our question we have to ask ourselves <em>how many electrons combine to make -73pC of charge? </em>

The answer is since one electron carries a charge of -1.6*10^{-19}C, the number n of electrons that make up -73pC (-73*10^{-12}C) are

n= \dfrac{-73*10^{-12}C}{-1.6*10^{-19}C/e}

\boxed{n= 4.56*10^8e.}

Thus, the housefly lost about 456 million electrons to the surface!

Technician A says test lights are great for quick tests on non-computerized circuits. Technician B says you can use a test light
Tpy6a [65]

Answer:

that technician A is right

Explanation:

The test lights are generally small bulbs that are turned on by the voltage and current flowing through the circuit in analog circuits, these two values ​​are high and can light the bulb. In digital circuits the current is very small in the order of milliamps, so there is not enough power to turn on these lights.

From the above it is seen that technician A is right

What happens when the temperature of a substance is increased?
Amiraneli [1.4K]
When the temperature of a substance is increased, the kinetic energy of the particles of the substance is increased as well.

This can lead to thermal expansion such as an increase in length of the substance or increase in volume of the substance.

 This can also lead to change of state of the substance, for example change of state from solid to liquid or from liquid to vapor.
