Answer:

The magnetic field is 24.2 mT.

Explanation:

The magnetic field can be calculated with the following equation:

$B = \frac{\mu_{0}iN}{L}$

Where:

i: is the current = 5.57 A

N: is the number of turns = 5*850 turns (it is five close-packed)

L: is the length = 1.23 m

$\mu_{0}$ : is the permeability = 4π*10⁻⁷ T*m/A

Hence, the magnetic field is:

$B = \frac{4\pi \cdot 10^{-7} T*m/A*5.57 A*5*850}{1.23 m} = 0.0242 T = 24.2 mT$

Therefore, the magnetic field is 24.2 mT.

A proton travels through a region of uniform magnetic field at an angle \thetaθ relative to the magnetic field. The magnitude of

MArishka [77]

Answer:

$\theta=15.52^{\circ}$

Explanation:

The magnitude of the force of a moving cahrge, in our case a proton, trought a magentic field is given by:

$F=|q||vB|sin(\theta)$ (1)

where:

q is the proton charge ( $q=1.6*10^{-19} C$ )

v is the proton velocity ( $v=5*10^{5} m/s$ )

B is the magnetic field (B = 1.17 T)

Now, we just need to solve the equaton (1) for \theta.

$\theta=sin^{-1}\left(\frac{F}{qvB}\right)$

But the force F = ma, then:

m is the mass of proton ( $m=1.67*10^{-27} kg$ )

a is the acceleration ( $a=1.5*10^{13} m/s^{2}$ )

$\theta=sin^{-1}\left(\frac{m_{p}a}{q_{p}vB}\right)$

$\theta=sin^{-1}\left(\frac{1.67*10^{-27}*1.5*10^{13}}{1.6*10^{-19}*5*10^{5}*1.17}\right)$

$\theta=15.52^{\circ}$

If the atomic mass of Sodium-18 is 18.02597 u, what is the binding energy?

Klio2033 [76]

Answer:

<h3>The binding energy of sodium Na=<em>5.407791×10⁹J</em></h3>

Explanation:

<h3>Greetings !</h3>

Binding energy, amount of energy required to separate a particle from a system of particles or to disperse all the particles of the system. Binding energy is especially applicable to subatomic particles in atomic nuclei, to electrons bound to nuclei in atoms, and to atoms and ions bound together in crystals.

<h2>Formula : Eb=(Δm)c²</h2><h3>where:Eb= binding energy</h3><h3> .Δm= mass defect(kg)</h3><h3> c= speed of light 3.00×10⁸ms¯¹</h3><h2 /><h3><u>Given</u><u> </u><u>values</u></h3>

m= 18.02597
c=3.00×10⁸ms¯¹

<h3><u>required </u><u>value</u></h3>

Eb=?

<h3><u>Solution:</u></h3>

Eb=(Δm)c²
Eb=(18.02597)*(3.00*10⁸ms¯¹
Eb=5.407791*10⁹J

Diagram B D c с Which car has: Ke = 100 PE=0? * 1 point A B C D

erma4kov [3.2K]

Answer:

The car C has KE = 100, PE = 0

Explanation:

The principle of conservation of energy states that although energy can be transformed from one form to another, the total energy of the given system remains unchanged.

The energy that a body possesses due to its motion or position is known as mechanical energy. There are two kinds of mechanical energy: kinetic energy, KE and potential energy, PE.

Kinetic energy is the energy that a body possesses due to its motion.

Potential energy is the energy a body possesses due to its position.

From the principle of conservation of energy, kinetic energy can be transformed into potential energy and vice versa, but in all cases the energy is conserved or constant.

In the diagram above, the cars at various positions of rest or motion are transforming the various forms of mechanical energy, but the total energy is conserved at every point. At the point A, energy is all potential, at B, it is partly potential partly kinetic energy, However, at the point C, all the potential energy has been converted to kinetic energy. At D, some of the kinetic energy has been converted to potential energy as the car climbs up the hill.

Therefore, the car C has KE = 100, PE = 0
