Answer:

The torque is  [tex]\tau = B * m sin(\phi )[/tex]

Explanation:

Generally when current flow through a rectangular loop the magnetic dipole generated we can denote this as  [tex]\vec m[/tex]

Here k is the length of the side of one side of the rectangular loop

Now when this loop is place in a magnetic field, the torque it experience is mathematically represented as

      [tex]\vec \tau = \vec B \ X \ \vec m[/tex]

Here  X stands for cross - product

From the question we are told that the angle between the vector ( [tex]\vec m[/tex])perpendicular to the plane of the coil and magnetic field(B) as [tex]\phi[/tex]

So

=>     [tex]\tau = B * m sin(\phi )[/tex]

Answer:

The number of turns is  [tex]N  = 1750 \ turns [/tex]

Explanation:

From the question we are told that

  The inner radius is [tex]r_i =  12.0 \  cm  =  0.12 \  m[/tex]

   The outer radius is  [tex]r_o =  15.0 \  cm  =  0.15 \  m[/tex]

   The current it carries is [tex]I =  1.50 \  A[/tex]

    The magnetic field is  [tex]B  =   3.75 mT = 3.75 *10^{-3} \  T[/tex]

   The distance from the center is [tex]d =  14.0 \ cm  =  0.14 \  m[/tex]

Generally the number of turns is mathematically represented as

    [tex]N  =  \frac{2 *  \pi  * d  *  B}{ \mu_o *  r_o }[/tex]

Generally  [tex]\mu_o[/tex] is the permeability of free space with value  

    [tex]\mu_o  =  4\pi * 10^{-7} \ N/A^2[/tex]

So

  [tex]N  =  \frac{2 *  3.142   * 0.14 *  3.75 *10^{-3} }{ 4\pi * 10^{-7}  * 0.15  }[/tex]

  [tex]N  = 1750 \ turns [/tex]

Answer: 211.75m

Explanation:

Listing everything the question gives you:

Vi = 5.5

a = 2.5

t = 11

ΔX = ?

Then pick a kinematic equation to solve for the missing variable

I used this one: Δx = Vit + [tex]\frac{1}{2} at^2[/tex]

When you plug in all ur variables you get Δx = 211.75m

The object has travelled a distance of 211.75 meters.

We have an object moving with an initial velocity of 5.5 m/s.

We have to determine how far will it have traveled during the time of its acceleration.

The rate of change of velocity with respect to time is called Acceleration.

a = dv/dt

According to the question -

initial velocity = u = 5.5 m/s

acceleration = a = 2.5 m/s²

time = t = 11 seconds

Therefore -

S = ut + [tex]\frac{1}{2} at^{2}[/tex]

S = 5.5 x 11 + 0.5 x 2.5 x 11 x 11

S = 211.75 meters

Therefore, the object has travelled a distance of 211.75 meters.

Answer:

6.71dm³

Explanation:

Given parameters:

Initial Volume of hydrogen gas  = 8.98dm³

Initial Temperature  = 38.8°C; in Kelvin  = 38.8 + 273  = 311.8K

Final temperature = -39.9°C; in Kelvin  = -39.9 + 273  = 233.1K

Unknown:

Final volume = ?

Solution:

To solve this problem, we apply the Charles's law. It states at;

   "The volume of a fixed mass (mole) of a gas varies directly as its absolute temperature if the pressure is constant".

  Mathematically;

          [tex]\frac{V_{1} }{T_{1} }[/tex]   =      [tex]\frac{V_{2} }{T_{2} }[/tex]

V and T are temperature values

1 and 2 are the initial and final states

 Insert the parameters and solve for V₂

      [tex]\frac{8.98}{311.8 }[/tex]   = [tex]\frac{V_{2} }{233.1}[/tex]

         V₂ x 311.8 = 8.98 x 233.1

Answer:

(a) Ascend at 0.8 vertical meter/meter

(b) Descend at -0.2·√2 vertical meter/meter

(c) In the (-0.6, -0.8) direction. The path begins at 45° to the horizontal

Explanation:

The given equation of the shape of the hill is z = 2000 - 0.005·x² - 0.01·y²

The current location = (60, 40, 1966)  

The direction of the positive x-axis = east

The direction of the positive y-axis = north

(a) Walking due south = Reducing the y-value 40

From the equation, the elevation varies inversely with the motion towards the north

Therefore, walking south increases the elevation, and we ascend

The rate is given by the partial derivative at in the -j direction, which is 0.02

The rate is therefore 40 × 0.02 = 0.8

(b)The unit vector in the northwest direction u = 1/√2·(-1, 1)

∴ The rate = (-0.01(60), -0.02(40))·u = (-0.6, -0.8)·1/√2·(-1, 1) = -0.2·√2

Therefore we descend

(c) The slope is largest in the grad of the function at the point (60, 40) which is given as follows;

d(2000 - 0.005·x² - 0.01·y² )/dx, d(2000 - 0.005·x² - 0.01·y² )/dy = (-0.6, -0.8)

Therefore, the direction is tan⁻¹(-0.8/-0.6) ≈ S 36.87° W

The slope =(√((-0.4)² + (-0.8)²) = 1

Therefore, the angle is 45° to the horizontal.

Encoding

Explanation:

Encoding is the initial learning of information. Encoding is the process of passing new information coming from sensory input  into our brain so that it can be easily retrievable. In a nutshell, it is the sum total of the processes by which external information such as the list of items your mother asked you to pick up at the grocery store to be converted into a manner that can be stored within the brain and recalled later from long-term memory.

Encoding has to do with transferring external stimuli into short term and subsequently long-term memory.

Answer:

162

Explanation:

When the amplitude of the wave is 8 units, the corresponding energy of the wave is 128 units. Therefore, option C is correct.

The term amplitude is defined as the maximum distance moved by a point on a vibrating body or wave calculated from its equilibrium position.

We have given,

first amplitude, A = 1, corresponding energy = 2

second amplitude, A = 2, corresponding energy = 8

The energy of a string at  a given amplitude is calculated as follows;

E ∝ A²

Energy varies as the square of the change in amplitude.

If amplitude of one has energy of two

Amplitude of 2 (double of 1)

= ( 2 x 2 ) = 4 x 2

= 8  4 times the energy at amplitude of 1.

Then for 8 units of amplitude change

8 x 8 = 64 x 2

= 128  

Thus, When the amplitude of the wave is 8 units, the corresponding energy of the wave is 128 units, option C is correct.

Answer:

[tex]F=-870\ N[/tex]

Explanation:

Net Force

The net force applied to an object of mass m that moves at an acceleration a is given by:

F=m.a

The acceleration can be calculated by the equations of the constant acceleration motion:

[tex]\displaystyle a=\frac{v_f-v_o}{t}[/tex]

Where vf is the final speed, vo is the initial speed, and t is the time.

Substituting the given values:

[tex]\displaystyle a=\frac{1-30}{2}=\frac{-29}{2}=-14.5\ m/s^2[/tex]

The force absorbed by his seat belt:

[tex]F=60\ kg\cdot (-14.5\ m/s^2)[/tex]

[tex]\boxed{F=-870\ N}[/tex]

Force absorbed by the seatbelt is : 870 N

Given data :

mass of body = 60 kg

Initial velocity ( V₁ ) = 30 m/s

Final velocity ( V₂ ) = 1 m/s

Time = 2 secs

Determine the force absorbed by the seat belt

Force = Mass * acceleration  --- ( 1 )

where ;

acceleration = Δ v / t  ---- ( 2 )

Δ v = ( 30 - 1 ) = 29 m/s

t = 2 secs

Back to equation ( 2 )

acceleration = 29 / 2 = 14.5 m/s²

∴ Force exerted on seatbelt

F = m * a

  = 60 kg * 14.5 m/s²  =  870 N

Hence we can conclude that the force absorbed by his seatbelt is 870 N

According to A, the measurement of the potential drop is 12 volts, i.e

The measurement of potential difference [tex]=v_1 -v_2[/tex]

= 12 volts which is correct.

But according to B, a measurement of 12 volts means there are 12 volts on each side of the switch ([tex]v_1= 12[/tex] volts and [tex]v_2=12[/tex] volts), i.e

According to the claim of B, the potential difference (or drop) across the terminals is

[tex]v_1-v_2= 12-12=0[/tex] but the measured potential drop is 12 volts, so B is wrong.

Hence, Tech B is correct.

[tex]h=-16t^2+vt+h_0[/tex]

[tex]h=-16t^2+50t+7[/tex]

We need to find the amount of time the baseball is in the air before it hits the ground. ATQ,

h = 0

[tex]-16t^2+50t+7=0\\\\t=\dfrac{-50 \pm \sqrt{50^2-4\times (-16)(7)} }{2(-16)}\\\\t=\dfrac{-50 + \sqrt{50^2-4\times (-16)(7)} }{2(-16)}, \dfrac{-50- \sqrt{50^2-4\times (-16)(7)} }{2(-16)}\\\\t=-0.134\ s,3.25\ s[/tex]

Neglecting negative value, t = 3.25 s

So, the baseball will hit the ground at t = 3.25 seconds.

Answer:

ΔE = 1.031 eV

Explanation:

For this exercise let's calculate the energy of the photons using Planck's equation

          E = h f

wavelength and frequency are related

         c = λ f

         f = c /λ

let's substitute

         E = h c /λ

let's calculate

         E = 6.63 10⁻³⁴ 3 10⁸/1064 10⁻⁹

         E = 1.869 10⁻¹⁹ J

let's reduce to eV

         E = 1.869 10⁻¹⁹ J (1 eV / 1.6 10⁻¹⁹ J)

        E = 1.168 eV

therefore the electron affinity is

         ΔE = E - 0.137

         ΔE = 1.168 - 0.137

         ΔE = 1.031 eV

The electron affinity of thulium in units of electron volts per atom is; ΔE ≈ 1.031 eV

From Planck's equation, we can find the energy of the photons when given wavelength as;

E = hc/λ

Where;

h is Planck's constant = 6.626 × 10⁻³⁴ J.s

c is speed of light = 3 × 10⁸ m/s

λ is wavelength

We are given;

wavelength; λ = 1064 nm = 1064 × 10⁻⁹ m

Thus;

E = (6.626 × 10⁻³⁴ × 3 × 10⁸)/(1064 × 10⁻⁹)

E2 = 1.868 × 10⁻¹⁹ J

Converting to eV gives;

E2 = (1.868 × 10⁻¹⁹)/(1.6 × 10⁻¹⁹)

E2 = 1.1675 eV

We are given E1 = 0.137 eV.

Now, electron affinity is simply change in energy. Thus;

ΔE = 1.1675 - 0.137

ΔE ≈ 1.031 eV

One way:

The ball returned to the thrower's hand after 5 seconds.  It spent 2.5 seconds going up, and 2.5 seconds coming back down.

Use the formula Distance = (1/2) (acceleration) (time squared)

Distance = (1/2) (gravity) (2.5 sec)

Distance = (1/2) (9.8 m/s ²) (6.25 sec² )

Distance = (4.9 m/s²) (6.25 sec²)

Distance = 30.63 meters

Another way:

The thrower threw the ball straight up at 25 m/s.

It sailed upward for 2.5 seconds.

At the top of its trip, before it started falling, its speed was zero.

Its average speed was (1/2) (25+0) = 12.5 m/s

At an average speed of 12.5 m/s for 2.5s, the ball rose (12.5x2.5) = 31.25m.

(Why are the two answers different ?

Because if the ball was thrown straight up at 25 m/s, it would actually return to the thrower in 5.1 seconds, not 5.0 seconds.

So if you use the acceleration of gravity to solve the problem, you get one answer, but if you use 5.0sec to solve it, you get a slightly different one.)
