Determine the correlation between coronal mass ejections from the Sun to the accumulation of the rare and valuable isotope He3 t

hat has a high concentration on the Moon.
its for a project i appreciate the help
its an open ended question so feel free to give lots of detail
because of the nature of this question and the need for a quality answer i will award brainliest where i see fit and this question is worth a lot of point

Most ejections originate from active regions on the Sun's surface, such as groupings of sunspots associated with frequent flares. These regions have closed magnetic field lines, in which the magnetic field strength is large enough to contain the plasma.

A professional boxer hits his opponent with a 1025 N horizontal blow that lasts 0.150 s. The opponent's total body mass is 116 k

mylen [45]

Answer:

The impulse is $I = 153.8 \ N \cdot s$

The opponents velocity is $v= 1.33 m/s$

The opponents head recoils velocity $v_r = 30.8 \ m/s$

Explanation:

From the question we are told that

The force of the blow is $F= 1025 \ N$

The duration of the blow is $t = 0.150$

The mass of the opponent is $m_o = 116 \ kg$

The mass of the opponents head is $m_h = 5 \ kg$

The impulse the boxer imparts is mathematically represented as

$I = F * t$

substituting values

$I = 1025 * 0.150$

$I = 153.8 \ N \cdot s$

The impulse can also be mathematically evaluated as

$I = m_o * v$

substituting values

$153.8 = 116 * v$

$v= \frac{153.8}{116}$

$v= 1.33 m/s$

The recoil velocity is mathematically represented as

$v_r = \frac{I}{m_h}$

substituting values

$v_r = \frac{153.8}{5}$

$v_r = 30.8 \ m/s$

A strip 1.2 mm wide is moving at a speed of 25 cm/s through a uniform magnetic field of 5.6 t. what is the maximum hall voltage

Alex787 [66]

The equation for Hall voltage Vh is:

Vh=v*B*w, where v is the velocity of the strip, B is the magnitude of the magnetic field, and w is the width of the strip.

v=25 cm/s = 0.25 m/s
B=5.6 T
w= 1.2 mm = 0.0012 m

We input the numbers into the equation and get:

Vh= 0.25*5.6*0.0012 = 0.00168 V

The maximum Hall voltage is Vh= 0.00168 V.

Assume that the particle has initial speed viviv_i. Find its final kinetic energy KfKfK_f in terms of viviv_i, MMM, FFF, and DDD

NeX [460]

Answer:

KE= 1/2mv²

Explanation:

The kinetic energy of a body is the energy possessed by virtue of the body in motion

Given the parameters

m which is the mass of the body

v which is the velocity of the body too

K.E = kinetic energy

The expression for the kinetic energy of a body is given as

KE= 1/2mv²

A heat engine accepts 200,000 Btu of heat from a source at 1500 R and rejects 100,000 Btu of heat to a sink at 600 R. Calculate

diamong [38]

To solve the problem it is necessary to apply the concepts related to the conservation of energy through the heat transferred and the work done, as well as through the calculation of entropy due to heat and temperatra.

By definition we know that the change in entropy is given by

$\Delta S = \frac{Q}{T}$

Where,

Q = Heat transfer

T = Temperature

On the other hand we know that by conserving energy the work done in a system is equal to the change in heat transferred, that is

$W = Q_{source}-Q_{sink}$

According to the data given we have to,

$Q_{source} = 200000Btu$

$T_{source} = 1500R$

$Q_{sink} = 100000Btu$

$T_{sink} = 600R$

PART A) The total change in entropy, would be given by the changes that exist in the source and sink, that is

$\Delta S_{sink} = \frac{Q_{sink}}{T_{sink}}$

$\Delta S_{sink} = \frac{100000}{600}$

$\Delta S_{sink} = 166.67Btu/R$

On the other hand,

$\Delta S_{source} = \frac{Q_{source}}{T_{source}}$

$\Delta S_{source} = \frac{-200000}{1500}$

$\Delta S_{source} = -133.33Btu/R$

The total change of entropy would be,

$S = \Delta S_{source}+\Delta S_{sink}$

$S = -133.33+166.67$

$S = 33.34Btu/R$

Since $S\neq 0$ the heat engine is not reversible.

PART B)

Work done by heat engine is given by

$W=Q_{source}-Q_{sink}$

$W = 200000-100000$

$W = 100000 Btu$

Therefore the work in the system is 100000Btu
