Each photon has an energy of 730 MeV in the center-of-momentum reference frame. When a proton and an antiproton collide, they can annihilate each other, producing two photons.

The energy of each photon can be determined using the conservation of energy and momentum. In the center-of-momentum reference frame, the total momentum of the system is zero before and after the collision, and the total energy is conserved. First, let's calculate the initial energy of each particle. Since they both have an initial kinetic energy of 730 MeV, their total energy is 2 x 730 MeV = 1460 MeV.

In the center-of-momentum reference frame, this energy is shared equally between the proton and antiproton. When they collide, they annihilate each other and produce two photons. Since the momentum of the system is zero, the two photons must have equal and opposite momenta, and their energies must be equal. Let's call the energy of each photon "E". Using the conservation of energy and momentum, we can write: 2 x 730 MeV = 2E Solving for E, we get: E = 730 MeV.

Therefore, each photon has an energy of 730 MeV in the center-of-momentum reference frame. This is the maximum energy that can be produced in this type of annihilation, since all of the initial energy is converted into the energy of the two photons.

In the center-of-momentum reference frame, the energy of each photon produced by the annihilation of a proton and an antiproton, each with an initial kinetic energy of 730 MeV, is 730 MeV.

In the center-of-momentum reference frame, the total initial kinetic energy of the system is equal to the total energy after annihilation. Since the momentum of the system is conserved, the net momentum before and after the collision is zero. Therefore, the momenta of the two particles cancel each other out. As a result, the two photons produced will have equal energy and travel in opposite directions.

To find the energy of each photon, we can start by calculating the total initial kinetic energy:

The total energy after annihilation is equal to the initial kinetic energy. Since there are two photons, each photon will have half the total energy:

Explanation:

Given

\(s=s_0+v_0t+\frac{a_0t^2}{2}+ \frac{j_0t^3}{6}+\frac{S_0t^4}{24}+\frac{ct^5}{120}\)

Solving (a): Units and dimension of \(s_0\)

From the question, we understand that:

\(s \to L\) --- length

\(t \to T\) --- time

Remove the other terms of the equation, we have:

\(s=s_0\)

Rewrite as:

\(s_0=s\)

This implies that \(s_0\) has the same unit and dimension as \(s\)

Hence:

\(s_0 \to L\) --- dimension

\(s_o \to\) Length (meters, kilometers, etc.)

Solving (b): Units and dimension of \(v_0\)

Remove the other terms of the equation, we have:

\(s=v_0t\)

Rewrite as:

\(v_0t = s\)

Make \(v_0\) the subject

\(v_0 = \frac{s}{t}\)

Replace s and t with their units

\(v_0 = \frac{L}{T}\)

\(v_0 = LT^{-1}\)

Hence:

\(v_0 \to LT^{-1}\) --- dimension

\(v_0 \to\) \(m/s\) --- unit

Solving (c): Units and dimension of \(a_0\)

Remove the other terms of the equation, we have:

\(s=\frac{a_0t^2}{2}\)

Rewrite as:

\(\frac{a_0t^2}{2} = s_0\)

Make \(a_0\) the subject

\(a_0 = \frac{2s_0}{t^2}\)

Replace s and t with their units [ignore all constants]

\(a_0 = \frac{L}{T^2}\\\)

\(a_0 = LT^{-2\)

Hence:

\(a_0 = LT^{-2\) --- dimension

\(a_0 \to\) \(m/s^2\) --- acceleration

Solving (d): Units and dimension of \(j_0\)

Remove the other terms of the equation, we have:

\(s=\frac{j_0t^3}{6}\)

Rewrite as:

\(\frac{j_0t^3}{6} = s\)

Make \(j_0\) the subject

\(j_0 = \frac{6s}{t^3}\)

Replace s and t with their units [Ignore all constants]

\(j_0 = \frac{L}{T^3}\)

\(j_0 = LT^{-3}\)

Hence:

\(j_0 = LT^{-3}\) --- dimension

\(j_0 \to\) \(m/s^3\) --- unit

Solving (e): Units and dimension of \(s_0\)

Remove the other terms of the equation, we have:

\(s=\frac{S_0t^4}{24}\)

Rewrite as:

\(\frac{S_0t^4}{24} = s\)

Make \(S_0\) the subject

\(S_0 = \frac{24s}{t^4}\)

Replace s and t with their units [ignore all constants]

\(S_0 = \frac{L}{T^4}\)

\(S_0 = LT^{-4\)

Hence:

\(S_0 = LT^{-4\) --- dimension

\(S_0 \to\) \(m/s^4\) --- unit

Solving (e): Units and dimension of \(c\)

Ignore other terms of the equation, we have:

\(s=\frac{ct^5}{120}\)

Rewrite as:

\(\frac{ct^5}{120} = s\)

Make \(c\) the subject

\(c = \frac{120s}{t^5}\)

Replace s and t with their units [Ignore all constants]

\(c = \frac{L}{T^5}\)

\(c = LT^{-5}\)

Hence:

The magnitude of the force exerted on the 0.02 C point charge in a 400 N/C electric field is 8 N. It is important to note that the force is a vector quantity, meaning it has both magnitude and direction. In this case, the direction of the force would depend on the polarity of the charge and the direction of the electric field.

The magnitude of the force exerted on a point charge in an electric field can be determined using the formula:

F = q * E

Where: F is the force exerted on the charge, q is the magnitude of the charge, and E is the magnitude of the electric field.

In this case, the magnitude of the electric field is given as 400 N/C, and the magnitude of the point charge is 0.02 C.

Substituting these values into the formula, we get:

F = (0.02 C) * (400 N/C)

Calculating this, we find:

F = 8 N

Therefore, the magnitude of the force exerted on the 0.02 C point charge in a 400 N/C electric field is 8 N. It is important to note that the force is a vector quantity, meaning it has both magnitude and direction. In this case, the direction of the force would depend on the polarity of the charge and the direction of the electric field.

to find the modulus of elasticity MoE at 23% of moisture content based on the already given modulus of elasticity of 12% moisture content we need to consider a shrinkage behavior of material. the expected MoE comes out to be approximately \(6,836 N/mm².\)

given information:

Modulus of elasticity at 12% moisture content =7,920 N/mm²

resultant shrinkage or final shrinkage percentage FSP = 30%

To calculate the expected MoE at 23% moisture content we have the following equation:

MoE-23% =   \(MoE-12%\) \((1 - FSP (23 - 12) / (100 - 12))\)

MoE-23% = \(7,920 N/mm² × (1 - 0.30 × (23 - 12) / (100 - 12))\)

MoE-23% =\(7,920 N/mm² × (1 - 0.30 × 11 / 88)\)

MoE-23% = \(7,920 N/mm² × (1 - 0.1364)\)

MoE-23% = \(7,920 N/mm² × 0.8636\)

MoE-23% =  \(6,836 N/mm²\)

therefore the expected modulus of elasticity at 23% moisture content comes out to be approx \(6,836 N/mm²\).

Explanation:

No, the co-efficient of friction cannot have a value such that a skier would be able to slide uphill at a constant velocity.

The co-efficient of friction represents the amount of resistance to motion between two surfaces in contact. When moving uphill, the force of gravity is acting against the skier's motion, which increases the frictional force. In order to maintain a constant velocity, the force of the skier pushing forward would have to match the force of friction, but with an increased frictional force, it would require a greater force from the skier to maintain that velocity. Therefore, it is not possible for a skier to slide uphill at a constant velocity due to the increased co-efficient of friction.
The answer is no, the coefficient of friction cannot have a value that would allow a skier to slide uphill at a constant velocity. The coefficient of friction is a measure of the resistance between two surfaces, in this case, the skis and the snow. When sliding uphill, the skier must overcome both friction and the gravitational force pulling them downhill. To slide uphill at a constant velocity, an external force would need to be applied, such as pushing or propelling themselves uphill. The coefficient of friction cannot be adjusted to overcome the force of gravity without an external force being applied.

RS is a composition of rotation and reflection in the Euclidean plane E². The precise description of RS depends on the specific properties of the rotation R and reflection S.

In general, if R and S have the same axis or line of symmetry, the composition RS results in a translation. If R and S have intersecting lines of symmetry, RS yields a glide reflection. If R and S have perpendicular lines of symmetry, RS produces a rotation.

It is important to consider special cases, such as parallel lines of symmetry, coinciding axes, or perpendicular lines of reflection, as they may lead to different outcomes.

Explanation:

r = Radius of wheel

v = Initial linear speed

3v = Final linear speed

Initial angular speed is given by

\(\omega_i=\dfrac{v}{r}\)

Final angular speed after time \(t\) is given by

\(\omega_f=\dfrac{3v}{r}\\\Rightarrow \omega_f=3\dfrac{v}{r}=3\omega_i\)

The angular acceleration of the wheel will give us how the angular speed of the wheel changes.

From the equations of rotational motion we have

\(\omega_f=\omega_i+\alpha t\\\Rightarrow 3\omega_i=\omega_i+\alpha t\\\Rightarrow \alpha=\dfrac{3\omega_i-\omega_i}{t}\\\Rightarrow \alpha=\dfrac{2\omega_i}{t}\)

True, the indirect method is used to determine total power in a parallel circuit when that power is determined from the total current, total resistance, and source voltage.

The indirect method of calculating power in a parallel circuit is used when it is not feasible to measure the current flowing through each individual resistor. It is found by multiplying the total resistance of the circuit (RT) by the square of the total current (IT), or by using the total voltage (VT) squared and dividing by the total resistance (RT).

The indirect method is used to determine total power in a parallel circuit when that power is determined from the total current, total resistance, and source voltage. The equation to use for this is Power = Voltage x Current. Therefore, the total power in a parallel circuit can be determined by multiplying the source voltage by the total current, divided by the total resistance.

The formula to calculate power is given by P = IV, where P stands for power, I stands for current, and V stands for voltage. Power is usually measured in watts (W), current is measured in amperes (A), and voltage is measured in volts (V).A parallel circuit consists of multiple paths, each containing a resistor.

The current through each resistor in a parallel circuit varies, and each resistor has its own voltage drop. The total resistance of a parallel circuit is less than the smallest resistance in the circuit.

The formula for calculating total power in a parallel circuit is

P = IT² × RT,

where IT is the total current and RT is the total resistance.

This formula assumes that the total voltage of the circuit is known. The formula can also be written as

P = VT²/RT,

where VT is the total voltage in the circuit.
