Climate and weather are related but different. Which of the following describes the climate of a place?
iren2701 [21]

Climate. What does it mean?

<em>Climate is a long-term weather, or recurring every time. Examples of climate? </em><u><em>Every day, the desert is hot the day and cold in the night.</em></u><em> This won't change, at least for hundreds, thousands, millions of years. This is climate.</em>

Weather. What does it mean?

<em>Weather is short-term, usually not recurring every time. Examples of weather? </em><u><em>Today is very sunny.</em></u><em> This will change-for all we know, tomorrow will be cloudy and rainy!</em>

<em />

This is why your answer will <u>NOT</u> be a meteorologist predicts that tomorrow will be sunny and warm. This is weather, because it is only <em>tomorrow.</em>

<em />

This is why your answer will <u>NOT</u> be fertile soil makes farms in the region very productive. This does not relate to weather, or climate.

This is why your answer will <u>NOT</u> be the temperature dropped below freezing every night last week. This will only be "last week", not the week right now or the week after this week.

<em><u>Therefore, your answer is "Thunderstorms frequently occur in the summer. </u></em>This is because that's the climate in that part- thunderstorms always happen.

a stone is dropped from top of a tower of 50m high ,simltaneously another stone is thrown upward with a speed of 20m/s find the
aleksklad [387]
At the time that I'll call ' Q ', the height of the stone that was
dropped from the tower is

             H = 50 - (1/2 G Q²) ,

and the height of the stone that was tossed straight up
from the ground is

             H  =  20Q - (1/2 G Q²) .

The stones meet when them's heights are equal,
so that's the time when

                         <span>50 - (1/2 G Q²)  =  20Q - (1/2 G Q²) .

This is looking like it's going to be easy.

Add  </span><span>(1/2 G Q²)  to each side.
Then it says
                                             50  =  20Q

Divide each side by 20:          2.5  =  Q .

And there we are.  The stones pass each other

                                       2.5 seconds

after they are simultaneously launched.
