Which is the cause of the suns magnetic properties ?
A) upward movement or super heated gases in the convection zone
B) uneven churning of plasma
C) rapid spinning of metals in the core
D) uniform clockwise rotation of charger particles
Answer:
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.
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.

Which statement describes the motion of a ball as it drops onto a vertical spring?
a. The acceleration of the ball decreases as the spring shrinks.
b. The accIleration of the ball decreases as the spring extends.
c. The velocity of the ball changes from positive to negative as the spring shrinks.
d. The velocity of the ball changes from negative to positive as the spring extends.
Answer:
F = M a Newton's second law
F = - K x force exerted by compressed spring
a = - K x / M
a) is true because the ball originally is accelerated due to gravity and this acceleration will decrease as the spring in compressed
One could argue for (d) if the downward direction was designated as negative
Prior to maximum compression of the spring the velocity would negative and as the spring began to extend (and the ball began move upward) the velocity of the ball would change from negative to positive

A playground merry-go-round spins about its axis with negligible friction. A child moves from the center of the merry-go-round to the rim. For this system, indicate which of the following quantities change.
A. Potential energy
B. Angular momentum
C. Mass
D. Moment of inertia
E. Angular speed
F. Rotational kinetic energy
Answer:
B
Explanation:
In this process on merry go round there is not any external torque so angular momentum will be conserve. Mass is always conserved.

75÷864=0.09
Answer: 0.09g/cm³
Why is running or jogging good aerobic excercise? Explain
Answer:
Running is faster, uses more kilojoules and demands more effort from the heart, lungs and muscles than jogging. Running requires a higher level of overall fitness than jogging. Both running and jogging are forms of aerobic exercise.
Explanation:
A car moves with an average speed of 45 mph. How long does a car take to travel 90 miles?
Answer:
It took 2 hours
Explanation:
[tex]{ \bf{time = \frac{distance}{speed} }} \\ [/tex]
distance is 90 miles
speed is 45 miles per hour
[tex]t = \frac{90}{45} \\ \\ t = 2 \: h[/tex]
Answer:
2 hours
Explanation:
45 times 2 is 90

How can radio waves & microwaves communicate over similar distances?
what is 342 m/s in kilometers per hour?
Answer: 1231.2 km/h
Explanation: 342 x 3.6 ( because 1 m/s equal 3.6 km/h)
Convert: 110 km/h to m/s
Answer:
30.5555556 m/s
You can write like "30.56 m/s".
Answer:
Below
Explanation:
You can convert km/h to m/s by dividing the value by 3.6
110 km/h / 3.6 = 30.5556 m/s
*not sure if your teacher wants you to round to sig figs for this but here it is anyways. Because 110 has 2 sig figs it would be :
31 m/s
Hope this helps! Best of luck <3
Round 0.010229 to four sig figs
It would be 0.01023.
0.010229 has 5 sig. fig.'s (leading zeros do not count)
So rounding to 4 sig. fig.'s is just a matter of rounding off the last digit, which leaves you with 0.01023.

why is there potential for wind energy in the upper himalayanx
Answer:
Favorable sites include the tops of smooth, rounded hills; open plains and water; and mountain gaps that funnel and intensify wind. Wind resources are generally more favorable for electricity generation at higher elevations above the earth's surface
in the Newton's Third Law of Motion state three characteristics
Answer:
Newton's third law: If an object A exerts a force on object B, then object B must exert a force of equal magnitude and opposite direction back on object A. This law represents a certain symmetry in nature: forces always occur in pairs, and one body cannot exert a force on another without experiencing a force itself.

how is light reflected from a prism
Answer:
White light entering a prism is bent, or refracted, and the light separates into its constituent wavelengths. Each wavelength of light has a different colour and bends at a different angle. The colours of white light always emerge through a prism in the same order—red, orange, yellow, green, blue, indigo, and violet.
Which statement is true?
