Answer:

This would depend on the intensity or the size of a fire.

Explanation:

For instance, a small fire could be described as: kindled, flickering, dancing (in the case of a candle flame), smoldering, or crackling.

A medium size fire, such as a camp fire or a fireplace could be described as: crackling, blazing, burning, or roaring.

While a large or very intense fire (such as a forest fire or a house fire) could be described as: roaring, blazing, burning out of control, consuming, raging, or destroying.

If you were more looking for synonyms of ‘fire’, here are a few of my favorites: flame, blaze, incinerate, immolation, and inferno. (Edited to add a few I remembered: pyre, conflagration, and scorching.)

Answer:

Fire is something that's red and sorta orange is hot and can burn you but fire can be good and bad at some points for example fire can be used as a campfire,fireplace at home,and lighting candles. Fire is also very dangerous tho ,you can burn yourself if your not careful it can light your house on fire and that wouldn't be very safe. In simple words i would say fire is something that can have advantages and disadvantages.

Ahhh hope thats alright im on online classes but i wanted to help!!

Sonar is a technology that uses sound waves to calculate the distance to an object. Explain why you think sonar is useful for sc
Margarita [4]

Answer:

<em>Sonar can be used to measure the depth of the seabed or the distance of any object, animal or a man-made vessel any other objects </em>

Explanation:

  • A sound wave or sound pulse is projected into the water.
  • If any object tends to come in the way of the pulse, an echo is produced or the signal is reflected back.
  • A transducer measures the strength of this signal and hence determines the depth of the object or the sea.

This is much better way of measuring distances under the sea since light alone is not able to pierce through the ocean after a certain distance.

A powerful sonar blast can help in taking multiple measurements at a time, while even a laser will find it difficult to reach below 3 km of depth.

Answer:

E) C₂H₄(g) + H₂(g) ⇒ C₂H₆(g)

Explanation:

Which ONE of the following is an oxidation–reduction reaction?

A) PbCO₃(s) + 2 HNO₃(aq) ⇒ Pb(NO₃)₂(aq) + CO₂(g) + H₂O(l). NO. All the elements keep the same oxidation numbers.

C) SO₃(g) + H₂O(l) ⇒ H₂SO₄(aq). NO. All the elements keep the same oxidation numbers.

D) CO₂(g) + H₂O(l) ⇒ H₂CO₃(aq). NO. All the elements keep the same oxidation numbers.

E) C₂H₄(g) + H₂(g) ⇒ C₂H₆(g). YES. <u>C is reduced</u> and <u>H is oxidized</u>.
