Answer:

c

Explanation:

the wires are made of too many conductors

C.

If a power line were broken then power would not reach the light. Which is possible.

If a wire to the light or to the box in your house was broken your light would not receive power, therefore not turn on. Again possible.

If the power plant does not produce enough electricity, although unlikely, that would cause you to not be able to turn on your light. Unlikely but it would be true is it happened.


Finally C is not likely, your wires in your house are most likely made of copper but too many conductors in the wire, not only wouldn’t happen, but would most likely not interrupt your light working.

The question asks what is NOT a possible cause. C is the only not possible.

You havent attached the choices so we cant tell u the answer

Answer:

I do not see the options but this is what I know.

Explanation:

At the boiling temperature, adding heat energy converts the liquid into a gas WITHOUT RAISING THE TEMPERATURE. In this case, the energy added to the liquid goes into breaking the bonds between the liquid molecules without causing the temperature to change. The same thing happens when a solid changes into liquid.

Sound, earthquakes, and waves in water are mechanical waves because they require a physical ______________________ to transport energy.



Disturbance


Electromagnetic field


Location


Medium

Answers

Answer is disturbance

Sound, waves are all propagation of energy. Transport of this energy require a physical medium. Thus option D is correct.

What is mechanical waves?

Mechanical waves are a form of energy transfer by oscillation of matter and they require a medium to propagate. Sound wave is a longitudinal wave which is only passing through a medium of air. Air disturbance causes these sound waves.

Longitudinal waves are those where the direction of oscillation of matter is along the direction of propagation.  Electromagnetic waves does not require a medium to travel.

Waves in water originates from the pressure difference in water earthquakes is caused by seismic waves which are transverse waves, where the oscillation of matter is perpendicular to the direction of propagation.

Hence, sound, earthquakes, and waves in water are mechanical waves because they require a physical medium.

On a hot summer day, air rises most quickly when it is above a

forest

lake

desert

river

Answers

It would be Lake because the water bacteria is evaporating into clouds

On a hot summer day, air rises most quickly when it is above a desert. The correct option is C.

What is a desert?

A desert is a barren area of land with little precipitation and, as a result, hostile living conditions for plant and animal life.

The lack of vegetation exposes the ground's unprotected surface to denudation. Arid or semi-arid regions cover roughly one-third of the Earth's land surface.

Although the majority of deserts, such as the Sahara in North Africa and the deserts of the southwestern United States, Mexico, and Australia, occur at low latitudes.

Arid climates have less cloud cover than humid climates, and cloud tops reflect a significant amount of the sun's energy back into space, reducing surface heating. On a hot summer day, air rises the fastest above a desert.

Thus, the correct option is C.
