Answer:

Solstice usually refers to the condition when there occurs the longest duration of day and night and during this time the north pole of the earth is tilted at the farthest distance from the location of the sun. There are two types of the solstice, namely the summer and the winter solstice.

In the case of the northern hemisphere or the upper half of the equator, the summer solstice usually occurs in June 21st and the winter solstice occurs in December 21st.

The locations on earth where the sunlight is directly incident during the time of summer solstice are the regions lying in the tropic of cancer namely, India, Mexico, the southern portion of China and the Bahamas.

The relative humidity would be ________% if the actual water vapor in the air was 4 grams per cubic meter, the air's capacity to
AveGali [126]

Answer:

50%

Explanation:

Humidity is the amount water vapor present in the atmosphere.

Relative humidity is defined as the ratio of partial water vapor present in air to the actual water vapor at a particular temperature. It is expressed in percentage and the higher the percentage RH, the more the saturated water vapor present in the atmosphere and vice versa.

It is expressed mathematically as shown;

RH = actual water vapor in air/saturated water vapor × 100%

If the actual water vapor in the air was 4 grams per cubic meter and the air's capacity to hold water vapor was 8 grams per cubic meter

Actual water vapor = 4g/cm³

Air's water capacity (saturated water vapor) = 8g/cm³

RH = 4/8×100

RH = 50%

The generator at a power plant produces AC at 20,000 V. A transformer steps this up to 355,000 V for transmission over power lin
Masja [62]

Answer:

Number of coil in the output is 39938

Explanation:

We have given a step up transformer

Input voltage of transformer, that is primary voltage v_p=20000volt

Output voltage, that is secondary voltage v_s=355000volt

Number of turns in primary N_p=2250

For transformer we know that \frac{V_p}{V_s}=\frac{N_p}{N_s}

\frac{20000}{355000}=\frac{2250}{N_s}

N_s=39937.5

As the number of turns can not be in fraction so number of turns in the output coil is 39938

A girl rolls a basketball across a basketball court. The ball slowly decelerates at a rate of -0.20m/s^2. If the initial velocit
Dafna1 [17]

By equation of motion :

2as=v^2-u^2\\\\s=\dfrac{v^2-u^2}{2a}\\\\s=\dfrac{0^2-2^2}{2\times( -0.2)}\\\\s=10\ m

Now, it is given that it stops after 5 seconds of motion and time at that point is 12:00.

So, time when it started is 11 : 59 : 55.

Therefore, distance travelled is 10 m.

Hence, this is the required solution.
