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.

deff fn [24]

Answer:

Frequency = 24 × 10⁸ Hz

Explanation:

Given the following data;

Speed = 3 × 10⁸ m/s

Wavelength = 0.125 meters

To find the frequency of the electromagnetic wave;

Mathematically, the speed of a wave is given by the formula;

Speed = Wavelength × frequency

Substituting into the formula, we have;

3 × 10⁸ = 0.125 × frequency

Frequency = (3 × 10⁸)/0.125

Frequency = 24 × 10⁸ Hz

Solenoid 2 has twice the diameter, twice the length, and twice as many turns as solenoid 1. How does the field B2 at the center
klemol [59]

Complete Question

The complete question is shown on the first uploaded image

Answer:

The correct option is  option 3

Explanation:

From the question we are told that

   The diameter of solenoid 1 is  d_1

   The length of solenoid 1 is   L_1

    The  number of turns of solenoid is  N_1

   The diameter of solenoid 2 is  d_2 = 2d_1

   The length of solenoid 2 is   L_2 = 2L_1

    The  number of turns of solenoid  2 is    N_2 = 2 N_1

Generally the magnetic in a solenoid is mathematically represented as

     B  =  \frac{\mu_o *  N  *  I }{L}

From this equation we see that

     B  \ \alpha \  \frac{N}{L}

     B   =  C   \frac{N}{L}

Here C stands for constant

=>   C =  \frac{B *  \frac{L}{N}

=>    \frac{B_1 *  \frac{L_1}{N_1}   = \frac{B_2 *  \frac{L_2}{N_2}

=>  \frac{B_1}{B_2 }  =  \frac{N_1 L _2}{ N_2L_1}

=>   \frac{B_1}{B_2 }  =  \frac{N_1 * (2 L_1)}{ (2 N_2)L_1}

=>   \frac{B_1}{B_2 }  =  1

=>   B_2 = B_1
