Q:

What characteristic is shared by sunspots, solar flares, and coronal mass ejections? Select the two correct responses.

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.

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.

Lack of basic services in community​

There are many consequences that result from the lack of basic services in a community​ but i shall focus on these three as they are very major impacts

-Educational Impact

Basic service like Water,Electricity ,Mobility and close Proximity to market place has a major impact on the ability of a person pursue educational attainments.we live in a modern world and without power(as) electricity we can not do much of studying in this times

-Insecurity

The Human mind is built with a default setting of Survival.Without the basic services provide persons of low moral will tend to go into illegal acts to survive as the basic needs are necessary for survival

-Poverty

For a community to  grow it is necessary that the right environment is made available for growth and if these requirements are not meet in form of basic services in community​ the community falls under the threat of falling into poverty

Explanation:

Acceleration is defined as the rate of change of velocity.

Acceleration = (Change in velocity) / time taken

Acceleration = (Final velocity - initial velocity) / time

As the object velocity changes by the same amount in each second, it means the acceleration is constant.

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

[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.

Substitute the values into the formula.

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

Solve inside the parentheses.

[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.

unit of speed is the meter per second (m/s

Explanation:

Some Extra Information! :)

Speed is a measure of how fast something is travelling. The most common units of speed are metres per second (m/s), kilometres per hour (km/h) and miles per hour (mph). In a typical car journey the speed of the car will change. The distance divided by the time will calculate the average speed of the car.

teleportation (artificial or natural over wormholes )

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.

The ball is hurled upward into space, it climbs steadily until it collides with an obstruction in its path.

All mass-bearing objects are attracted by gravitational force. Because it consistently attempts to bring masses together rather than push them apart, the gravitational force is referred to as attractive.

As we know, the gravitational force is given by:

[tex]\rm F = \dfrac{Gm_1m_2}{r^2}[/tex]

Where G is the gravitational constant.

m1 and m2 are masses.

r is the distance between the masses.

As we know,

There is no gravity in space, the ball is not subject to the effects of gravity. When a ball is hurled upward into space.

It climbs steadily until it collides with an obstruction in its path.

Thus, the ball is hurled upward into space, it climbs steadily until it collides with an obstruction in its path.

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.
