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.

If a girl is running along a straight road with a uniform velocity 1.5m/s find her acceleration ​
Jlenok [28]

Answer:

Dear user,

Answer to your query is provided below

Acceleration is zero because of no change in velocity.

Explanation:

Remember that velocity is a vector quantity and a vector can change in 3 ways

•Magnitude only

•Direction only

•Both magnitude and direction.

Now the magnitude of velocity (speed) can stay constant while the direction is changing. This is the case in circular motion.

In the question above, it is mentioned that the girl is moving along a straight road. Therefore no change in direction of velocity.
