While john is traveling along a straight in interstate highway, he notices that the mile marker reads 242 km. John travels until he reaches the 147 km marker and then retraces his path to the 161 km marker. What is John's resultant displacement from the 242 km marker? How far has he traveled answer in units of km

Answer:

The resultant displacement [tex]\Delta x _{1 , 3} = 81 \ km[/tex]

The total distance traveled by john is  [tex]x_t =109 \ km[/tex]

Explanation:

From the question we are told that

      The first position of john from the finish point   is [tex]x_1 = 242 \ km[/tex]

       The second position of john from the finish point is   [tex]x_2 = 147 \ km[/tex]

        The third position of john from the finish point is [tex]x_3 = 161 \ km[/tex]

Generally the displacement from the 242 km  marker is mathematically represented as

          [tex]\Delta x _{1 , 3} = x_1 - x_3[/tex]

Here we used [tex]x_3[/tex] instead of  [tex]x_2[/tex] because [tex]x_3[/tex] is further than [tex]x_2[/tex] from the finish point

=>       [tex]\Delta x _{1 , 3} = 81 \ km[/tex]

Generally the total distance traveled by John is  mathematically evaluated as

         [tex]x_t = [x_1 - x_2 ] + [x_3 - x_2][/tex]

=>       [tex]x_t = [242 - 147 ] + [161 - 147][/tex]

=>       [tex]x_t =109 \ km[/tex]

The amount of work done to bring an electron (q = −e) from right side of hydrogen nucleus to left side in the k shell is__________. Let the radius (r) of atom is 52 pm a) Zero b) infinity c) Fr d) 2Fr

Answers

Answer:

d) 2Fr

Explanation:

We know that the work done in moving the charge from the right side to the left side in the k shell is W = ∫Fdr from r = +r to -r. F = force of attraction between nucleus and electron on k shell. F = qq'/4πε₀r² where q =charge on electron in k shell  -e and q' = charge on nucleus = +e. So, F = -e × +e/4πε₀r² = -e²/4πε₀r².

We now evaluate the integral from r = +r to -r

W = ∫Fdr

= ∫(-e²/4πε₀r²)dr

= -∫e²dr/4πε₀r²

= -e²/4πε₀∫dr/r²

= -e²/4πε₀ × -[1/r] from r = +r to -r

W = e²/4πε₀[1/-r - 1/+r] = e²/4πε₀[-2/r} = -2e²/4πε₀r.

Since F = -e²/4πε₀r², Fr = = -e²/4πε₀r² × r = = -e²/4πε₀r and 2Fr = -2e²/4πε₀r.

So W = -2e²/4πε₀r = 2Fr.

So, the amount of work done to bring an electron (q = −e) from right side of hydrogen nucleus to left side in the k shell is W = 2Fr

Is it possible to generate emf without rotating the coil explain

Answers

Answer:

It's not possible.

Explanation:

It's not possible.

This is because when a coil is rotated in a magnetic field about a line which is not the axis of the coil, the magnetic coil with a link going through the coil will change and thus an EMF will be produced.

Now, this EMF produced is gotten as a result of cutting action through lines of magnetic flux gotten through rotation (physical movement) of the coil through space.

Faraday's law allows finding the result for whether it is possible to create induced electromotive force (emf) without rotating the coil are:  

Producing a pulsating voltage is possible change the magnetic field the area of ​​the loop. Producing constant voltage is not possible since a uniform change of some parameter is required and the only one that can change is the angle constantly.

Faraday's Law states that by varying the magnetic flux an electromotive force is produced.

           [tex]emf = - \frac{d \Phi_B }{dt} \\\Phi_B = B . A[/tex]

Where emf is the induced voltage, Ф the magnetic flux, B the magnetic field and A the area of ​​the loop

We can write the flow explicitly.

          Ф =  B A cos θ.

Therefore we see that there is some form of having this changing flow:

Changing the magnitude of the magnetic field. Changing the area of ​​the loop. Changing the angle between the normal to the area and the magnetic field direction.

The first two methods are used in pulsating fields, that is, a voltage is obtained for a short period of time.

The last method is used in equipment that can give indicated voltage in a constant way, it is the method used to produce electricity, it consists of an external system that rotates the loop with a constant speed and produces an output voltage.

In conclusion using Faraday's law we can find the result for whether it is possible to create induced electromotive force (emf) without rotating the coil are:  

Producing a pulsating voltage is possible change the magnetic field the area of ​​the loop Producing constant voltage is not possible since a uniform change of some parameter is required and the only one that can change is the angle constantly.

6. A total of 135 J of work is done on a gaseous refrigerant as it undergoes compression. If
the internal energy of the gas increases by 114 J during the process, what is the total amount
of energy transferred as heat? Has energy been added to or removed from the refrigerant as
heat?

Answers

Answer:

Eh = 21 [J]

Removed as heat.

Explanation:

This is a case of energy conservation, we have to take into account the energies that go in and out of the system. In this case, 135 [J] of energy are entered in the form of work of the compressor to the chamber where the refrigerant is compressed, now of these 135 [J] 114 [J] were used as internal energy, this internal energy is used to increase the pressure and temperature of the refrigerant.

In this way the rest of the energy of the 135 [J] was lost in the form of heat to determine this loss of energy, we simply perform the arithmetic subtraction.

Eh = 135 - 114 = 21 [J]

Eh = 21 [J]

Answers

Answer:

We show added energy to a system as +Q or -W

Explanation:

The first law of thermodynamics states that, in an isolated system, energy can neither be created nor be destroyed;

Energy is added to the internal energy of a system as either work energy or heat energy as follows;

ΔU = Q - W

Therefore, when energy is added as heat energy to a system, we show the energy as positive Q (+Q), when energy is added to the system in the form of work, we show the energy as minus W (-W).

Suppose an object has a velocity of -7 m/s at t=0. What will the velocity be after 4 seconds if the acceleration of the object is +1 m/s^2?

Answers

Answer:

Vf = - 3 [m/s]

Explanation:

To solve this problem we must use the following equation of kinematics.

[tex]v_{f} =v_{o} +a*t[/tex]

where:

Vf = final velocity [m/s]

Vo = initial velocity = - 7 [m/s]

a = acceleration = 1 [m/s²]

t = time = 4[s]

Now replacing:

Vf = -7 + (1*4)

Vf = - 3 [m/s]

A car's acceleration is 3m/s2. If the car started at rest and it only took 10s for the car to reach this acceleration, what is the car's final velocity?

Answers

Answer:

30m/s

Explanation:

From law of motion equation

Vf= Vi + at

Where Vf= final velocity

Vi= initial velocity=0(the car started at rest)

a= acceleration= 3m/s2

t= time= 10s

Then substitute into the equation to get the final velocity.

Vf= 0+(10×3)

Vf= 30m/s

Hence, the car's final velocity is 30m/s

What force is necessary to pull a 10 kg sled across a horizontal surface at a constant velocity if the coefficient of kinetic friction between the sled and the ground is 0.25?

Answers

Answer:

Any force greater than 24.5 N

Explanation:

To find the frictional force is the 1st step. this can be found by multiplying the coefficient of friction and the normal force. normal force can be found by multiplying gravity (we will say 9.8 m/s/s) and the mass which is 10. You then multiply the result by the coefficient of friction which is 0.25 and it leads us to an answer to 24.5 N. This means that if you pull with exactly 24.5 N, the sled wouldnt move. So you need a force greater than 24.5 N and we have our answer.

I hope I helped correct me if im wrong

A force of 25 N is necessary to pull a 10 kg sled across a horizontal surface at a constant velocity if the coefficient of kinetic friction between the sled and the ground is 0.25.

First, we will calculate the normal force (N), which, in a horizontal surface, has the same magnitude and opposite sense as the weight (W) of the sled.

[tex]|N| = |W| = m \times g = 10 kg \times \frac{9.8m}{s^{2} } = 98 N[/tex]

where,

m: mass of the sledg: Earth's gravity

Then, we will calculate the friction force (f) using the following expression.

[tex]f = \mu \times N = 0.25 \times 98 N = 25 N[/tex]

According to Newton's first law of motion, for the sled to move at a constant velocity, the sum of the force exerted (F) on the sled and the friction force (f) must be zero.

[tex]F + f = 0\\F = -f\\F = -25 N\\|F| = 25 N[/tex]

A force of 25 N is necessary to pull a 10 kg sled across a horizontal surface at a constant velocity if the coefficient of kinetic friction between the sled and the ground is 0.25.
