Which describes a difference between solar wind and a geomagnetic storm? Select the three correct answers. (2 points)
Solar wind sometimes results in geomagnetic storms, geomagnetic storms do not cause solar wind.
Geomagnetic storms travel at the speed of light, while solar wind takes four days to reach Earth.
Geomagnetic storms occur only occasionally, solar wind is constant.
Geomagnetic storms are associated with CMEs, solar wind is associated with the constant activity in the sun
Geomagnetic storms are constant, solar wind occurs only occasionally.

Answers

We have that the three correct answers are

"Solar wind sometimes results in geomagnetic storms, geomagnetic storms do not cause solar wind" is a correct statement from the definition above."Geomagnetic storms occur only occasionally, solar wind is constant."This statement is correct as the sun emission of solar wind particles are constant but Geomagnetic storms are occasional."Geomagnetic storms are associated with CMEs, solar wind is associated with the constant activity in the sun" This statement is correct as CMEs(  Coronal Mass Ejections) are sometimes the main reason for  Geomagnetic storms

We First define the two Phenomenons

Solar Winds

These are Particles such as Plasma and other Harmful particles Dispersed by the sun of the a galaxy that can be harmful to Humans.

Geomagnetic storm

A Geometric storm is a kind of storm that comes about because of the an attack of the solar wind on earths magnetic field above atmosphere.

Therefore

"Solar wind sometimes results in geomagnetic storms, geomagnetic storms do not cause solar wind" is a correct statement from the definition above.

"Geomagnetic storms travel at the speed of light, while solar wind takes four days to reach Earth." This is false as Geometric storms are the Phenomenons that emanate on earth.

"Geomagnetic storms occur only occasionally, solar wind is constant."This statement is correct as the sun emission of solar wind particles are constant but Geomagnetic storms are occasional.

"Geomagnetic storms are associated with CMEs, solar wind is associated with the constant activity in the sun" This statement is correct as CMEs(  Coronal Mass Ejections) are sometimes the main reason for  Geomagnetic storms

"Geomagnetic storms are constant, solar wind occurs only occasionally."This statement is False as Stated in the definitions above

In conclusion

The three correct answers are

"Solar wind sometimes results in geomagnetic storms, geomagnetic storms do not cause solar wind" is a correct statement from the definition above."Geomagnetic storms occur only occasionally, solar wind is constant."This statement is correct as the sun emission of solar wind particles are constant but Geomagnetic storms are occasional."Geomagnetic storms are associated with CMEs, solar wind is associated with the constant activity in the sun" This statement is correct as CMEs(  Coronal Mass Ejections) are sometimes the main reason for  Geomagnetic storms

An amusement park designer wants his swing to have a centripetal acceleration of 24 m/s2. If the velocity of the swing is 11 m/s, how long should the chain on the swing be?
A. 6.5 m
B. 5.5 m
C. 5.0 m
D. 6.0 m

Answers

Answer:

radius is C: 5.0 m

Explanation:

formular for centripetal acceleration:

[tex]a = \frac{ {V}^{2} }{r} [/tex]

a is acceleration

V is velocity

r is radius

[tex]24 = \frac{ {11}^{2} }{r} \\ \\ r = \frac{ {11}^{2} }{24} \\ \\ r = 5.0 \: m[/tex]

Answer: 5.0 meters (choice C)

This length is approximate.

==========================================================

Explanation:

The centripetal acceleration formula we use is

a = (v^2)/r

where v is the linear velocity and r is the radius. The swing moves in a circular path, so the chain acts as the radius. If we can find the radius, then we have found the chain length. The goal is to find r when a = 24 and v = 11

So we have...

a = (v^2)/r

24 = (11^2)/r

24 = 121/r

24r = 121

r = 121/24

r = 5.041667 approximately

r = 5.0 meters when rounding to the nearest tenth

The chain should be approximately 5.0 meters.

Answers

Answer:

2 m = E / c^2      where m is mass of electron

E = h v     where v is the frequency ( nu) of the incident photon

E = h c / y      where y is the incident wavelength (lambda)

2 m = h / (c y)

y = h / (2 m c)      wavelength required

y = 6.62 * 10E-34 / (2 * 9.1 * 10E-31 * 3 * 10E8)  m

To find the quantity of charge;

Mathematically, the quantity of charge with respect to electric potential is given by the formula;

[tex]Quantity \; of \; charge = \frac{Energy}{Electric \; potential}[/tex]

Substituting the values into the formula, we have;

An oil tanker has a mass of 400,000 tonnes. It is 500m long and 40m wide.
A.What is the minimum depth of the harbor it requires.?
B. Calculate the downward force
C. State the upward force
D. Draw a diagram to show the forces acting on the tanker.

Answers

Archimedes' principle allows us to solve this problem, find:

a) the submerged part h = 2.04 m

b) the downward force W = 3.9 10⁹ N

c) the upward force B = 4 10⁸ N

d) The free-body diagram  attach

The parameters given

 *  The tanker mass  with oil M = 400000 Tonnes (10³ kg/1 tonn) = 4 10⁸ kg

  * The length and width of the tanker l = 500m and w= 40m

To find

   * the submerged part of the tanker

   * The force in the tanker

   * free body diagram

Fluid mechanics exercises, the  Archimedes' principle says that the hydrostatic thrust of a fluidIn   on a body is equal to the weight of the desalted liquid.

        B  = [tex]\rho \ g \ V_{body}[/tex]

Where ρ is the density of the fluid in this case water (ρ = 1000 kg /m³), ​​g is the acceleration of gravity (g = 9.80 m / s²) and V_{body}  is the volume of the tanker.

a) In the attached diagram we can see the forces involved, we apply the equilibrium equation

            B - W = 0

             

The volume of the submerged tanker is

          V_{body} = l w h

Where l and w are the length and width of the tanker and h is the submerged quantity

We substitute

           ρ g (l w h) = W

           [tex]h = \frac{W}{\rho \ g\ l \ w}[/tex]

We calculate

           h = 4 10⁸ / (10³ 9.8 500 40)

           h = 2.04 m

The submerged quantity of tanker using Archimedes' principle is

h = 2.04m

b) The downward force on the tanker's weight

          W = m g

          W = 4 10⁸ 9.80

          W = 3.9 10⁹ N

c) the upward force is the thrust

            B = ρ g

            B = 1000 9.8 (500 40 2.04)

            B = 4 10⁸ N

d) in the attachment we can see a free body diagram with the two forces on the tanker: the weight down and the fluid push up

Archimedes' principle allows finding the submerged part of the tanker

h = 2.04 m
