The momentum of the plastic cart is less than the momentum of the lead cart. This is because the lead cart has more mass, so it takes more force to move it.

Since the same force was applied to both carts, the plastic cart will gain less momentum. This is because the same force on a more massive object will result in less acceleration and, therefore, less momentum.
To calculate the momentum, we use the equation:

Momentum = mass * velocity.

As both carts started from rest, their initial velocity was 0 m/s. After 1 s, the velocity of the plastic cart is greater than 0 m/s, and the velocity of the lead cart is also greater than 0 m/s. Since the lead cart has more mass, its velocity will be lower than the plastic cart, meaning its momentum will be lower. Therefore, both carts will have the same force applied to them, which will accelerate them to the same velocity. However, as the lead cart has a larger mass than the plastic cart, it will have a greater momentum than the plastic cart.

Therefore, after the force is removed at t = 1s, the momentum of the plastic cart will be less than the momentum of the lead cart.

The frequency of the second harmonic of the guitar string would be 1000 Hz.

The fundamental frequency, which is the lowest frequency a guitar string can produce, is produced when the string vibrates. The length, tension, and mass of the string all affect the fundamental frequency.

A guitar string's second harmonic has a frequency that is twice its fundamental frequency. This is due to the fact that the second harmonic has twice as many vibrational cycles per second as the fundamental frequency, making it the next higher frequency the string is capable of producing.

The frequency of the second harmonic of a guitar string is twice the fundamental frequency.

So, if the fundamental frequency is 500 Hz, then the frequency of the second harmonic would be:

2 x 500 Hz = 1000 Hz

Therefore, the frequency of the second harmonic of the guitar string would be 1000 Hz.

The velocity of the girl after she catches the ball is approximately -0.408 m/s (also in the opposite direction of the shore).

To solve this problem, we can apply the principle of conservation of momentum. The total momentum before the girl catches the ball should be equal to the total momentum after she catches it.

The momentum of an object is given by the product of its mass and velocity:

Momentum = mass × velocity

Given:

Mass of the girl (m₁) = 42.5 kg

Mass of the canoe (m₂) = 16 kg

Initial velocity of the girl and the canoe (u₁) = -0.15 m/s (negative because it's in the opposite direction of the shore)

Mass of the ball (m₃) = 3.0 kg

Initial velocity of the ball (u₃) = -5.0 m/s (negative because it's also in the opposite direction of the shore)

Final velocity of the girl after catching the ball (v₁) = ?

The total momentum before the girl catches the ball is given by:

Initial momentum = (m₁ + m₂) × u₁ + m₃ × u₃

The total momentum after the girl catches the ball is given by:

Final momentum = (m₁ + m₂ + m₃) × v₁

According to the principle of conservation of momentum, the initial momentum and final momentum should be equal:

(m₁ + m₂) × u₁ + m₃ × u₃ = (m₁ + m₂ + m₃) × v₁

Plugging in the given values:

(42.5 + 16) × (-0.15) + 3.0 × (-5.0) = (42.5 + 16 + 3.0) × v₁

(-10.125) + (-15.0) = (61.5) × v₁

-25.125 = 61.5 × v₁

Dividing both sides of the equation by 61.5:

v₁ = -25.125 / 61.5

v₁ ≈ -0.408 m/s

Therefore, after she catches the ball, the girl moves at a velocity of roughly -0.408 m/s (also away from the beach).

We can use the momentum conservation concept to address the problem. The overall momentum before to the ball being thrown and the total momentum following the girl catching the ball should be identical.

Given:

Mass of the girl (m₁) = 42.5 kg

Mass of the canoe (m₂) = 16 kg

Initial velocity of the girl and canoe (u) = 0.15 m/s

Mass of the ball (m₃) = 3.0 kg

Velocity of the ball (v₃) = 5.0 m/s

First, let's find the initial momentum before the ball is thrown. The initial momentum (Pᵢ) is the sum of the momenta of the girl, canoe, and ball.

Pᵢ = m₁u + m₂u + m₃u

    = (42.5 kg)(0.15 m/s) + (16 kg)(0.15 m/s) + (3.0 kg)(0.15 m/s)

Next, let's find the final momentum after the ball is caught by the girl. The final momentum (P_f) is the sum of the momenta of the girl, canoe, and ball.

P_f = (m₁ + m₃)(v_f)

Since we're looking for the velocity of the girl after catching the ball (v_f), we can rearrange the equation as follows:

v_f = P_f / (m₁ + m₃)

Substituting the given values, we have:

v_f = [m₁u + m₂u + m₃u] / (m₁ + m₃)

= [(42.5 kg)(0.15 m/s) + (16 kg)(0.15 m/s) + (3.0 kg)(0.15 m/s)] / (42.5 kg + 3.0 kg)

Calculating this expression:

v_f = (6.375 kg·m/s) / (45.5 kg)

   ≈ 0.14 m/s

Therefore, the velocity of the girl after she catches the ball is approximately 0.14 m/s.

The amount of energy (in joules) required to warm 4.37 g of silver by ΔT degrees Celsius can be calculated using the equation Q = 1.0488 * ΔT.

The specific heat capacity (C) of a substance is the amount of energy required to raise the temperature of 1 gram of that substance by 1 degree Celsius. In this case, the specific heat capacity of silver is 0.24 J/g°C.

To calculate the energy required to warm 4.37 g of silver, we need to multiply the mass (m) by the specific heat capacity (C) and the change in temperature (ΔT). The change in temperature is not provided in the question, so we'll assume it is given.

Let's assume the change in temperature is ΔT°C. The formula to calculate the energy (Q) is:

Q = m * C * ΔT

Substituting the given values:

Q = 4.37 g * 0.24 J/g°C * ΔT

The units of grams cancel out, and we are left with:

Q = 1.0488 J/°C * ΔT

So, the amount of energy (in joules) required to warm 4.37 g of silver by ΔT degrees Celsius can be calculated using the equation Q = 1.0488 * ΔT.

Explanation:

The concept of compactness is related to the curvature of space, as both are determined by the mass distribution of an object. The more compact an object is, the more it will curve space around it. Black holes, being the most dense objects in the universe, curve space to an extreme degree.

Student 2 is correct in pointing out that the Earth is denser than Jupiter, and thus has a higher compactness. However, the Earth's mass is significantly smaller compared to Jupiter's, so the amount of space it curves is also much smaller. In other words, the curvature caused by an object's mass depends on both its density and size.

In conclusion, both students are partially correct. Jupiter, being the largest planet in the solar system, does curve space more than the Earth due to its greater mass. However, the Earth is denser than Jupiter and has a higher compactness, meaning it does curve space to a greater degree for its size.

The values of the radius where the n=2, l=0 radial probability density has its maximum values are r = a₀/2

The probability density that can be found at a given distance from the nucleus for a particular electron is referred to as the radial probability density.

The radial probability density of an electron in the hydrogen atom at a distance r from the nucleus is determined by the equation,

R² * 4πr²dr

where R is the radial wave function and dr is the differential volume element.

The probability density, P, of a hydrogen atom's electron at a distance r from the nucleus with quantum numbers n and l are given by:

P(r) = 4πr²Ψ²(r)Ψ(n,l,r) is the radial wave function. r represents the distance between the electron and the nucleus.

In this case, n = 2 and l = 0. Therefore, the radial probability density for this scenario is:

P(r) = 4πr²Ψ²(r)

where n = 2 and l = 0.

For the radial probability density to have a maximum value, it must be differentiated with respect to r and set to zero, then resolved for r.

Ψ(r) = (1 / (4π)) × [(Z / a₀)³ × (2 - (Z / a₀) × r)] × e ^(-Zr / (2a₀))

The probability density function is shown in the image below. The probability density has its maximum values at a distance of r = a₀/2.

Therefore, the radial probability density has its maximum values are r = a₀/2.

The values of all sub-parts have been obtained.

(1).  The maximum factored load the beam can withstand is 45.2 kN/m.

(2).  The moment resistance of the cross-section is 291735.65 Nm.

(3).  The factored moment demand is 27939.6 Nm

1) To draw the governing shear and bending moment diagram for the factored load, we need to first calculate the maximum factored load that the beam can withstand.

The maximum factored load on the beam is given by:

Dead Load = 20 kN/m + 15 kN

                   = 35 kN/m.

Live Load = 2 kN/m + 1 kN

                = 3 kN/m.

Total Factored Load = 1.2 x Dead Load + 1.6 x Live Load

                                  = 1.2 x 35 kN/m + 1.6 x 3 kN/m

                                  = 45.2 kN/m.

The maximum factored load the beam can withstand is 45.2 kN/m.

The shear force and bending moment diagrams for the given factored load can be obtained as shown below:

Shear Force Diagram:

Bending Moment Diagram:

2) To calculate the moment resistance of the cross-section, we can use the formula:

MR = σst A'(d - a/2) + 0.85f'c A''(d - a/2)

Where, σst = yield stress of tension steel [σst = fy / γst],

γst = safety factor for tension steel [γst = 1.15A']

A' = area of tension steel, [A'' = b(d - a)].

Where,

b = width of the beam [b = 600 mm],  

d = total height of the beam [d= 1000 mm],

a = effective depth of tension steel [a = 920 mm]

f'c = compressive strength of concrete [f'c = 25 MPa],

MR = σst A'(d - a/2) + 0.85f'c A''(d - a/2)

MR = (400 / 1.15) x 10 x (1000 - 920/2) + 0.85 x 25 x 590 x (1000 - 920/2)

MR = 291735.65 Nm

The moment resistance of the cross-section is 291735.65 Nm.

3) To check if this cross-section is adequately designed to resist the factored bending moment (LRFD), we need to calculate the factored moment demand and compare it with the moment resistance.

The factored moment demand is given by:

MF = ϕ x Mu

Where,ϕ = resistance factor = 0.9, Mu = factored bending moment

Mu = 1.2 x Dead Load x L2 / 8 + 1.6 x Live Load x L2 / 8 + 1.2 x (Dead Load + Live Load) x L2 / 2

   = 1.2 x 35 x 152 / 8 + 1.6 x 3 x 152 / 8 + 1.2 x 38 x 152 / 2

   = 31044 Nm

MF = ϕ x Mu

     = 0.9 x 31044

    = 27939.6 Nm

The factored moment demand is 27939.6 Nm, which is less than the moment resistance of the cross-section, i.e., 291735.65 Nm.

Therefore, this cross-section is adequately designed to resist the factored bending moment.
