(a)

To determine

The average power delivered to the protons.

(a)

Expert Solution
Check Mark

Explanation of Solution

Given:

Each of the proton has a kinetic energy 10keV . Per second 1×109 protons are reaching the target at the end of the 1.50m long accelerator. Mass of the proton is 1.67×1027Kg .

Formula Used:

Write the expression for the power of the protons required to reach the end of the accelerator.

  P=n(Energyofeachproton)

Here, P is the required power and n is the number of protons reaching the target per second.

Calculation:

Substitute 1×109 for n and 10keV for energy of each protonin the above expression.

  P=(1×109s-1)(10keV)=(109s-1)((10keV)(1000eV)1keV)(1.6×1019J1eV)=1.6×106Js-1=1.6×106W

Conclusion:

Thus, the average power that must be delivered to the stream of protons is 1.6×106W .

(b)

To determine

The force acting on the protons.

Explanation of Solution

Given:

Each of the proton has a kinetic energy 10keV . Per second 1×109 protons are reaching the target at the end of the 1.50m long accelerator. Mass of the proton is 1.67×1027Kg .

Formula Used:

The protons will perform some work at the expense of the energy with which they are emitting from the accelerator.

Write the expression for the work done by the protons.

  W=(Energyofeachproton)t …… (1)

Here, W is the work done and t is the time required to eject one proton.

Write the expression for the net force on the stream protons.

  Fnet=WS …… (2)

Here, W is the work done, Fnet is the net force and S is the displacement.

Write the expression for the force on each proton.

  F=Fnet(numberofprotons) …… (3)

Calculation:

Substitute 1s for t and 1.6×106W for energy of eachproton in expression(1).

  W=(1.6×106W)(1s)=1.6×106J

Because of the application of this constant force on the protons, they reach to the end of the accelerator by traveling a distance 1.50 m.

Substitute 1.6×106W for W and 1.50m for S in expression (2).

  Fnet=1.6×106J1.50m=1.07×106N

Substitute 1×109 for the number of protons in expression (3).

  F=1.07×106N1×109=1.07×1015N

Conclusion:

Thus, the force applied to each protons is 1.07×1015N .

(c)

To determine

The velocity of protons just before hitting the target.

Explanation of Solution

Given:

Each of the proton has a kinetic energy 10keV . Per second 1×109 protons are reaching the target at the end of the 1.50m long accelerator. Mass of the proton is 1.67×1027Kg .

Formula Used:

Write the expression for the acceleration of each proton.

  a=Fmp …… (4)

Here, a is the acceleration and mp is the mass of each proton.

Write the expression for the final velocity of the protons just before hitting the target.

  vf2=2aS …… (5)

Here, vf is the final velocity and S is the displacement.

Calculation:

Substitute 1.07×1015N for F and 1.67×1027Kg for mp in expression (4).

  a=1.07×1015N1.67×1027Kg=6.41×1011ms-2

Substitute 6.41×1011ms-2 for a and 1.5m for S in expression (5).

  vf2=2(6.41×1011ms-2)(1.5m)=1.923×1012m2s-2

Simplify the above expression.

  vf=1.923×1012ms-1=1.38×106ms-1

Conclusion:

Thus, the speed of the protons just before hitting the target is 1.38×106ms-1 .

For each of the actions depicted below, a magnet and/or metal loop moves with velocity v→ (v→ is constant and has the same magnitude in all parts). Determine whether a current is induced in the metal loop. If so, indicate the direction of the current in the loop, either clockwise or counterclockwise when seen from the right of the loop. The axis of the magnet is lined up with the center of the loop. For the action depicted in (Figure 5), indicate the direction of the induced current in the loop (clockwise, counterclockwise or zero, when seen from the right of the loop). I know that the current is clockwise, I just dont understand why. Please fully explain why it's clockwise, Thank you
A planar double pendulum consists of two point masses \[m_1 = 1.00~\mathrm{kg}, \qquad m_2 = 1.00~\mathrm{kg}\]connected by massless, rigid rods of lengths \[L_1 = 1.00~\mathrm{m}, \qquad L_2 = 1.20~\mathrm{m}.\]The upper rod is hinged to a fixed pivot; gravity acts vertically downward with\[g = 9.81~\mathrm{m\,s^{-2}}.\]Define the generalized coordinates \(\theta_1,\theta_2\) as the angles each rod makes with thedownward vertical (positive anticlockwise, measured in radians unless stated otherwise).At \(t=0\) the system is released from rest with \[\theta_1(0)=120^{\circ}, \qquad\theta_2(0)=-10^{\circ}, \qquad\dot{\theta}_1(0)=\dot{\theta}_2(0)=0 .\]Using the exact nonlinear equations of motion (no small-angle or planar-pendulumapproximations) and assuming the rods never stretch or slip, determine the angle\(\theta_2\) at the instant\[t = 10.0~\mathrm{s}.\]Give the result in degrees, in the interval \((-180^{\circ},180^{\circ}]\).
