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.

Answer:

true

Explanation:

Answer:

International Bureau of Weights and Measures (BIPM) is an international organization founded to bring about the unification of measurement systems, to establish and preserve fundamental international standards and prototypes, to verify national standards, and to determine fundamental physical constants. The bureau was established by a convention signed in Paris on May 20, 1875, effective January 1876. In 1921 a modified convention was signed.  The convention provides for a General Conference that meets every four years to consider required improvements or modifications in standards. An International Committee of Weights and Measures, composed of 18 scientists elected by the conference, meets annually to monitor worldwide uniformity in units of measure.

Answer:

[tex]a)uf = 205 + 35 - 11 \\ = 240 - 11 \\ = 229j \\ b)q(heat \: transferd) = 229 - 205 - 11 \\ = 24 - 11 \\ = 13j \\ thank \: you[/tex]

The heat transferred is

a) u f = 205+35-11

      = 229 j

b) q (heat transferred ) = 223-205-11

   = 24-11

While a thermodynamic gadget passes thru an exchange in the state, a succession of states exceeded could be termed as a course of the device or direction of an alternate country. 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.

An asset whose price would not depend upon the course taken to attain that unique price is thought to as kingdom capabilities or point features. In contrast, those capabilities which do depend upon the direction from points are referred to as course features.

[tex]\\ \sf\longmapsto Acceleration=\dfrac{v-u}{t}[/tex]

[tex]\\ \sf\longmapsto Acceleration=\dfrac{15-0}{10}[/tex]

[tex]\\ \sf\longmapsto Acceleration=\dfrac{15}{10}[/tex]

[tex]\\ \sf\longmapsto Acceleration=1.5m/s^2[/tex]

Average acceleration is calculated using the following formula: Average Acceleration = Change in Velocity/ Time.

Acceleration is a fundamental concept in physics that measures the rate of change of an object's velocity with respect to time.

It quantifies how quickly an object's speed or direction of motion is changing.

Acceleration = Final velocity  − Initial velocity/ Time

                        = 15 − 0/ 10

                         = 15/ 10

                         = 1.5 m/s²    

Therefore, The cyclist's average acceleration  is 1.5 m/s²

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.

Hi, There! The Correct Answer is Below!

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.

HAVE A GREAT DAY

Explanation:

Force = mass × acceleration

Mass = 900kg

Acceleration = velocity ÷ time

Velocity = 60km/hr = 60 × 1000 ÷ 3600

Velocity = 60000 ÷ 3600

Velocity = 16.67m/s

To get the time

Velocity = Distance ÷ time

16.67 = 50 ÷ time

Cross multiply

16.67 × time = 50

time = 50 ÷ 16.67

time = 3 seconds

Acceleration = 16.67 ÷ 3

Acceleration = 5.56m/s²

Therefore, Force = 900 × 5.56

Force = 5004 Newton
