One astronomical unit (AU) is about 1.5 x 108 km. Explain why this is the same as 150 x 100 km.

Answers

Answer 1

Answer:

To change 150x106 km to scientific notation, the leading number must be reduced to a  

number between 1 and 9.99999.... To do this, one must dDIVIDE by 100, yielding 1.50.  

In order to keep the entire quantity the same, one must then MULTIPLY the exponential  

part of the number of 100. This is equivalent to increasing the exponent from 6 to 8.

Give a reasonable order-of-magnitude estimate of the number of golf balls that would fill a home
swimming pool

Answers

An order of magnitude is a number of the form 10^n such that can be used to compare magnitudes or quantities.

We will find that  the order of magnitude of golf balls that fill a home swimming pool is 10^6

In this case, we want to estimate the number of golf balls that would fill a home swimming pool.

We know that the diameter of a golf ball is D = 42.6mm = 0.0426m

And the volume of a sphere of diameter D is:

V = (4/3)*pi*(D/2)^3

where pi = 3.14

Then the volume of a single golf ball is:

V =  (4/3)*3.14*( 0.0426m/2)^3 = 0.00004 m^3

Now we need to find the average volume of a home swimming pool, we can use 48 m^3 (an average one) to do the general math.

To find the number of golf balls that enter in that volume, we need to do the quotient between the volume of the pool and the volume of a single ball:

N = (48 m^3)/(0.00004 m^3)  = 1,200,000

If we round this to the next order of magnitude: 10^6 (the exponent is the number of digits at the right of the one)

Then the order of magnitude of golf balls that enter in a home swimming pool is  10^6

acceleration of -0.0500 m/sec”, how long will it take the train to stop?

Answers

The time that takes for the train that is traveling with an initial velocity of 20.1 m/s to stop is 402 seconds.    

The time that will take for the train to stop can be calculated with the following kinematic equation:

[tex] v_{f} = v_{i} + at [/tex]   (1)

Where:

[tex] v_{f}[/tex]: is the final velocity = 0 (when it stops)

[tex] v_{i}[/tex]: is the intial velocity = 20.1 m/s

a: is the acceleration = -0.0500 m/s²

t: is the time =?

By solving equation (1) for t, we have:

[tex] t = \frac{v_{f} - v_{i}}{a} = \frac{0 - 20.1 m/s}{-0.0500 m/s^{2}} = 402 s [/tex]

Therefore, it will take 402 seconds for the train to stop.

A:

They tend to occur during active periods of the solar cycle. & They are caused by outward fluctuations of the sun's magnetic field.

Q:Drag each item to the correct location.

A: sunspot: cooler area on suns surface where the magnettic field emerges

solar flare: intense burst of radiation coming from the rapid release of magnetic energy

coronal mass ejection: large bubble of plasma from the rapid release of magnetic energy

Q: Which is the cause of the sun's magnetic properties?

A: uneven churning of plasma

Explanation:

took quick check

good luck yall

The uneven churning of plasma is the cause of the sun's magnetic properties, therefore the correct answer is option B.

What is a magnetic field?

A magnetic field could be understood as an area around a magnet, magnetic material, or an electric charge in which magnetic force is exerted.

For a simple bar magnet, N-pole and S-pole are the points on a magnet that have the strongest magnetic field. The magnetic field originates from the north pole and terminates in the south pole of a magnet.

The positively charged ions and negatively charged electrons that make up the plasma of the Sun move around a lot due to its high temperatures. Multiple intricate magnetic fields that twist and turn are produced by the moving plasma. A magnetic field is produced by the extremely hot plasma that escapes from the Sun as the solar wind.

Thus, The sun's magnetic properties are caused by uneven plasma churning, so option B is the correct answer.

If the route of change of kingdom is completely distinctive, route of alternate of the nation may be termed as thermodynamic manner.

The technique is described via a direction, which is the non-stop collection of consecutive states via which the machine passes, consisting of the initial nation, the intermediate states, and the very last state. The process has a course along the course.

Where G is the gravitational constant.

m1 and m2 are masses.

r is the distance between the masses.

As we know,

BRAINLIEST : A car starts from rest and accelerates at a rate of 40 m/s2 over a time if 2.4 s. How fast is the car going at the end of this time interval?

Please explain

Answers

Answer:

[tex]\boxed {\boxed {\sf 96 \ m/s}}[/tex]

Explanation:

We are asked to find the final velocity of the car given the acceleration and time. We can use the following kinematics equation to calculate the final velocity.

[tex]v_f=v_i+(a \times t)[/tex]

The car starts from rest, so the initial velocity is 0 meters per second. It accelerates a rate of 40 meters per square second over a period of time of 2.4 seconds.

[tex]v_i[/tex]= 0 m/s a= 40 m/s²t= 2.4 s

Substitute the values into the formula.

[tex]v_f= 0 \ m/s + ( 40 \ m/s^2 \times2.4 \ s)[/tex]

Solve inside the parentheses.

40 m/s/s * 2.4 s = 40 m/s * 2.4=96 m/s

[tex]v_f= 0 \ m/s + (96 \ m/s)[/tex]

Add.

[tex]v_f= 96 \ m/s[/tex]

The final velocity of the car is 96 meters per second.
