A circuit contains two resistors in series. The voltage drop across the first is 10 V. The voltage drop across the second is als
iragen [17]

The voltage provided by the power supply = 20 V

<h3>Resistors in series </h3>

The Voltage across resistors in series in a circuit is equal to the sum of the voltage drops across each resistor.

Therefore for two resistors in series the total voltage provided by the power supply is equivalent to the summation of the voltage drops acroos each resistor ( i.e 10 V + 10 V = 20 V )

Hence we can conclude that the voltage provided by the power supply is 20 V

A 0.10 kg meter stick is held perpendicular to a vertical wall by a 2.5 mm string going from the wall to the far end of the stic
il63 [147K]

Explanation:

a)

Sum of moments = 0 (Equilibrium)

T . cos (Q)*L = m*g*L/2

cos Q = \frac{\sqrt{(2.5^2 - L^2) } }{2.5}

T*\frac{\sqrt{(2.5^2 - L^2) } }{2.5} * L = 0.1 *9.81*L/2

T = \frac{2.4525}{\sqrt{(2.5)^2 - L^2} }

b) If the String is shorter the Q increases; hence, Cos Q decreases which in turn increases Tension in the string due to inverse relationship!

c)

T = \frac{1.962}{\sqrt{(2)^2 - L^2} }

What does the sun consume to produce energy and helium?
aev [14]
This reaction, known as nuclear fusion, converts hydrogen atoms into helium. The by-product of nuclear fusion in theSun's core is a massive volume ofenergy that gets released and radiates outward toward the surface of the Sunand then into the solar system beyond it.

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 0.676 m long section of cable carrying current to a car starter motor makes an angle of 57.7º with the Earth’s 5.29 x 10^−5T f
Studentka2010 [4]

Answer:

The current in the wire under the influence of the force is 216.033 A

Solution:

According to the question:

Length of the wire, l = 0.676 m

\theta = 57.7^{\circ}

Magnetic field of the Earth, B_{E} = 5.29\times 10^{- 5} T

Forces experienced by the wire, F_{m} = 6.53\times 10^{-3} N

Also, we know that the force in a magnetic field is given by:

F_{m} = IB_{E}lsin\theta

I = \frac{F_{m}}{B_{E}lsin\theta}

I = \frac{6.53\times 10^{-3}}{5.29\times 10^{- 5}\times 0.676sin57.7^{\circ}

I = 216.033 A
