If the sun is 400 times bigger than the moon, how couild the moon possibly cover the sun during a solar eclipse?​

Answers

Explanation:

the Moon passes between Earth and the Sun Even though the Moon is much smaller than the Sun, because it is just the right distance away from Earth, the Moon can fully block the Sun's light from Earth's perspective This completely blocks out the Sun's light

Answer:

It's all about perspective. The moon is far closer to the Earth than the Sun is, so they appear roughly the same size. If they were closer to each other, then obviously the moon wouldn't be large enough to cover a substantial amount of the sun's light. But given the huge distance both between them and the moon and the earth, to us they look relatively the same.

Well, let's see what we've got here:

                    ( 4⁻³ · 3⁴ · 4² )  /  ( 3⁵ · 4⁻² ) .

The two simple rules of exponents that we're

going to use here are:

-- Two multiply two numbers with the same base,

add their exponents.    Like   (A³) · (A²) = A⁵ .

But the bases have to be the same.

-- A negative power just means it belongs in the

other section of a fraction.

  A negative power on top means it belongs on the bottom.

  A negative power on the bottom means it belongs on top.

  Like    A⁻²  means  1/A² .  And  1/B⁻³  means  B³ .

That's all you need in order to clean up the big fraction

in the question.  But in order to see where you can use

these rules, you need to re-arrange things first.

Original:                          ( 4⁻³ · 3⁴ · 4² )  /  ( 3⁵ · 4⁻² )

Let's send the  4⁻³

to the bottom

where it belongs:              (   --  3⁴ · 4² )  /  4³ · ( 3⁵ · 4⁻² )

Not take that  4⁻² from

the bottom, and put it on

top, where it belongs:       (  4² · 3⁴ · 4² )  /  4³ · ( 3⁵    -- )

Multiply the 4²s on top:     (  4⁴ · 3⁴       )  /  ( 4³ · 3⁵ )

Now let me break this up.

Not changing anything, just

writing it in a different way:      ( 4⁴  /  4³ ) · ( 3⁴ / 3⁵ )

Look at the first fraction:  4⁴ / 4³ .

Divide top and bottom by  4³ , and it becomes just  4 .

Now look at the second fraction:  3⁴ / 3⁵ .

Divide top and bottom by  3⁴ , and it becomes just  1/3 .

So in the end, we're left with just      4 / 3 .

And THAT is exactly equal to the original big messy fraction

in the question.  It has exactly the same numerical value, but

you'd never know it when you see it, because it's a lot simpler.

There are a lot of other ways we could have manipulated and

massaged the original fraction, but the steps are the same:

-- Multiply numbers with the same base, by adding the exponents.

-- Remember that a number with a negative exponent belongs

in the other section of the fraction, with a positive exponent.

A 5.00 kg pendulum swings back and forth. At the top of its arc it reaches a height of 0.36 m. What is the velocity of the pendulum at the top of the arc?

0 m/s
7.2 m/s
2.7 m/s

Answers

Answer:

Gravitational potential energy = (mass) x (gravity) x (height)

Kinetic energy (of a moving object) = (1/2) (mass) x (speed)²

When the pendulum is at the top of its swing, its potential energy is

(mass) x (gravity) x (height)

= (5 kg) x (9.8 m/s²) x (0.36 m)

= (5 x 9.8 x 0.36) joules

17.64 joules .

Energy is conserved ... it doesn't appear or disappear ... so that number is exactly the kinetic energy the pendulum has at the bottom of the swing, only now, it's kinetic energy:

17.64 joules = (1/2) x (mass) x (speed)²

17.64 joules = (1/2) x (5 kg) x (speed)²

Divide each side by 2.5 kg:

17.64 joules / 2.5 kg = speed²

Write out the units of joules:

17.64 kg-m²/s² / 2.5 kg = speed²

(17.64 / 2.5) (m²/s²) = speed²

7.056 m²/s² = speed²

Take the square root of each side: Speed = √(7.056 m²/s²) = 2.656 m/s.

Looking through the choices, we're overjoyed to see that one if them is ' 2.7 m/s '. Surely that's IT !

A potential difference of 15 V produces a current of 0.60 amps in a piece of copper wire. What is the resistance of the wire?

9.0 Ω
18.0 Ω
25 Ω

Answers

Answer:

R = 25 Ohms

Explanation:

Given the following data;

Voltage (p.d) = 15 V

Current = 0.6 A

To find the resistance of the wire;

Ohm's law states that at constant temperature, the current flowing in an electrical circuit is directly proportional to the voltage applied across the two points and inversely proportional to the resistance in the electrical circuit.

Mathematically, Ohm's law is given by the formula;

[tex] V = IR[/tex]

Where;

V represents voltage measured in voltage.

I represents current measured in amperes.

R represents resistance measured in ohms.

[tex] R = \frac {V}{I} [/tex]

Substituting into the equation, we have;

[tex] R = \frac {15}{0.6} [/tex]

R = 25 Ohms

A light bulb used in homes converts electrical energy into light energy  The amount of light energy output by the lamp in 9.0 hours of use is 23.4 J.

What is electrical energy?

The ability of an atom's charged particles to initiate an activity or move an object is known as electrical energy.

The proportion of the device's useful energy transferred to the device's total energy input.

The input power of the light bulb = 52 w.

In 9.0 hours of use.

Hence,

52 x 9.0 = 468 J

The following equation calculates efficiency as a percentage and is represented as follows:

Efficiency is calculated as (Usable Energy Output/Total Energy Input) x 100%.

The lightbulb's efficiency is 5.0%.

(The light energy output/ 468) x 100% = 5%

So, the light energy output = 23.4 J

Therefore, the amount of light energy output by the lamp in 9.0 hours of use is 23.4 J.

The flow chart shows the life cycle of a star. Was this star smaller than our sun, about the same or bigger than our sun?

1. Bigger
2. About the same
3. Smaller ​

Answers

Correct answer is 1.

The star is bigger than our sun. The correct option is 1.

The flow chart of the life cycle of a star indicates that the star starts as a nebula, which is a cloud of gas and dust. The nebula can collapse due to gravitational forces and form a protostar. The protostar can then continue to contract and heat up until it reaches a temperature and density at which nuclear fusion can occur, leading to the star entering the main sequence phase.

The size of a star is determined by its mass, and the more massive a star is, the bigger it will be. Based on this information, we can infer that if a star follows the life cycle shown in the flow chart, starting from a nebula and eventually reaching the main sequence, it must be at least as massive as our sun or even more massive, since only stars with sufficient mass can become main sequence stars.

A 60 kg girl on a swing is pulled 1.5 meters back and then released. The girl oscillates at pi/3 radians per second.How far from equilibrium will the girl be in 4 seconds into the motion

Answers

Answer:

-0.75 m

Explanation:

The displacement of the girl is given by x = x₀cosωt where x₀ = maximum displacement of swing = 1.5 m, ω = angular frequency = π/3 rad/s and t = time of swing = 4 s

Substituting the values of the variables into the equation, we have

x = x₀cosωt

x = (1.5 m)cos(π/3 rad/s × 4 s)

x = (1.5 m)cos(2π/3)

x = (1.5 m)cos120°

x = 1.5 m × -0.5

x = -0.75 m

So, the girl is 0.75 m to the left of the equilibrium position 4 seconds into the motion.

Answers

Answer:

The ball and the wall experience the same force.

Explanation:

According to the third law of Newton, which states that "for every action, there is an equal and opposite reaction", this means that when an object 1 acts on object 2 with a certain force, object 2 also acts on object 1 with the same magnitude of force but in an opposite direction.

According to this question, a ball hits a wall with a certain force. This means that the wall will react on the ball with the same force magnitude, but in an opposite manner. Hence, the ball and the wall experience the same force.

To add to the complexity, those precious atoms face the peril of disintegrating into the void. Luckily, by now, they are feeling the influence of gravity to bring them safely together. Based on this sentence, the reader can infer that — A There was no gravity at the time of the Big Bang. B The most basic atoms were formed due to the force of gravity. C Gravity developed right after the first atoms fell apart. D The force of gravity helped collapse the newly created atoms.

Answers

Answer:

B The most basic atoms were formed due to the force of gravity.

Explanation:

Since the statement says that the atoms could have faced the peril of disintegrating into the void, this means that, they could have been destroyed by movement away into the void.

But, it also says that by now, they are feeling the influence of gravity to bring them safely together. This statement shows that gravity brings them (the atoms) together and thus doesn't allow them disintegrate into the void.

So, a reader can thus infer that the most basic atoms were formed due to the force of gravity since it doesn't allow the atoms disintegrate into the void.

So, B is the answer.

A person weighs 60 kg. The area under the foot of the person is 150 cm2. Find the pressure exerted on the ground by the person.

Answers

Answer:

Pressure = 39200 N/m²

Explanation:

Given the following data;

Mass = 60 kg

Area = 150 cm²

Conversion:

1 centimeter square = 0.0001 meter square

150 centimeter square = 150 * 0.0001 = 0.015 m²

To find the pressure exerted on the ground by the person;

Mathematically, pressure is given by the formula;

[tex] Pressure = \frac {Force}{area} [/tex]

First of all, we would determine the force exerted by the person.

Force = mass * acceleration due to gravity.

We know that acceleration due to gravity is equal to 9.8 m/s².

Substituting into the formula, we have;

Force = 60 * 9.8

Force = 588 Newton

Next, find the pressure;

[tex] Pressure = \frac {Force}{area} [/tex]

Substituting into the formula, we have;

[tex] Pressure = \frac {588}{0.015} [/tex]

Pressure = 39200 N/m²

In a few sentences, describe how the thermostat utilizes a bimetallic strip in order to turn a furnace on and off in one or two sentences.

Answers

Answer:

Explanation:

Bimetallic strips are used in thermostats for measuring and controlling temperature. The strip is connected to a switch and as the temperature changes, the strip flexes and opens or closes a contact. They are also used in ovens for measuring temperature. An electromechanical thermostat typically contains either a bi-metal coil or a metal strip. When the temperature changes, this coil or strip will move, causing a vial containing mercury to tip to one side. The mercury flows to one end of the vial, signaling that the heating or cooling needs to be turned on.

Answers

Answer:

Frequency

Explanation:

A period is the number of revolutions in a minute.

[tex] Period = \frac {time}{number \; of \; oscillations}[/tex]

Also, frequency can be defined as number of oscillation per unit time.

Mathematically, frequency is given by the formula;

[tex] Frequency = \frac {number \; of \; oscillations}{time}[/tex]

Thus, we can deduce that frequency of an oscillation is the inverse of the period (time) of oscillation.

Mathematically, period is expressed as;

[tex] Period = \frac {1}{frequency}[/tex]

This ultimately implies that, an object's period of oscillation can always be used to solve for frequency.
