In Ampere's law, B· ds = μ₀i, the integration must be over any: closed path.

So, the correct answer is D.

Ampere's law states that the integral of the magnetic field (B) around a closed path is equal to the product of the permeability of free space (μ₀) and the total current (i) enclosed by the path.

Mathematically, it is represented as B·ds = μ₀i.

In this equation, the integration must be over any "D. closed path."

This closed path is often referred to as an Amperian loop.

It is important that the path is closed because it ensures that the net magnetic field around the loop is considered, taking into account both the sources and sinks of the magnetic field.

There is no value of n that will give a focal length of 80 cm for a symmetric converging lens with radii of curvature of 50 cm.

We can use the lensmaker's equation to solve this problem:

1/f = (n-1)(1/R₁ - 1/R₂)

where:

f = focal length

n = index of refraction

R₁ = radius of curvature of the first surface

The magnitude of the velocity at time t=15.0 s will be approximately 44.3 m/s.

To solve this problem, we first need to find the horizontal and vertical components of the projectile's velocity at time t=15.0 s.

Given that the projectile is launched with initial velocity components Vox = 30 m/s and V₀y = 100 m/s, we can use the following kinematic equations to find the velocity components at any time t:

Vx = V₀x (constant)

Vy = V₀y - gt

where g is the acceleration due to gravity (9.8 m/s²).

Using the above equations, we can find the vertical component of the velocity at time t=15.0 s as:

Vy = V₀y - gt = 100 m/s - (9.8 m/s²)(15.0 s) = -32.0 m/s (downward)

Since there is no acceleration in the horizontal direction, the horizontal component of the velocity remains constant throughout the motion. Thus, the horizontal component of the velocity at time t=15.0 s is:

Vx = V₀x = 30 m/s

Now, we can use the Pythagorean theorem to find the magnitude of the velocity at time t=15.0 s:

V = √(V²x+ V²y) = √((30 m/s)² + (-32.0 m/s)²) = 44.3 m/s

Therefore, the magnitude of the velocity at time t=15.0 s is approximately 44.3 m/s.

E = (n²h²)/(8mL²)

Where n is the quantum number (1 for the ground state), h is Planck's constant, m is the mass of the electron, and L is the length of the box.

The longest-wavelength photon the electron can absorb corresponds to the energy difference between the ground state and the first excited state. This energy is given by:

ΔE = E₂ - E₁ = [(2²-1²)h²]/(8mL²) = (3h²)/(8mL²)

We can use this equation to solve for L, the length of the box:

ΔE = hc/λ

(3h²)/(8mL²) = hc/λ

L² = (3h²)/(8mcλ)

L = √[(3h²)/(8mcλ)]

L = 5.35 x 10^-10 m

Now we can find the wavelength of the next longest-wavelength photon the electron can absorb, which corresponds to the energy difference between the first excited state and the second excited state:

ΔE = E₃ - E₂ = [(3²-2²)h²]/(8mL²) = (5h²)/(8mL²)

The setup where the polarizing axis of the second polarizer is perpendicular to the axis of the first polarizer has the smallest transmitted intensity.

Polarizers work by allowing only certain polarizations of light to pass through while blocking the others. In this case, a vertically polarized electromagnetic wave is passing through two polarizers. The first polarizer only allows vertical polarization to pass through, while the second polarizer may or may not allow the same polarization to pass through depending on its orientation.

When the polarizing axis of the second polarizer is perpendicular to the axis of the first polarizer, it blocks all of the vertical polarization, resulting in the smallest transmitted intensity. This is because the electromagnetic wave cannot pass through the second polarizer if its polarization is blocked by the first polarizer.
On the other hand, if the polarizing axis of the second polarizer is parallel to the axis of the first polarizer, then the wave can pass through both polarizers without being blocked, resulting in the highest transmitted intensity.

We can begin by using Archimedes' principle which states that the buoyant force on an object is equal to the weight of the fluid displaced by the object.

Let's assume that the density of the fishing line and lead weight are negligible compared to the density of water.

The buoyant force acting on the float can be calculated as:

F_b = V_disp × ρ_water × g

where V_disp is the volume of water displaced by the float, ρ_water is the density of water, and g is the acceleration due to gravity.

Since the float is half submerged, the volume of water displaced is equal to half the volume of the float:

V_disp = (1/2) × (4/3) × π × (1.45 cm)^3 = 2.45 cm^3

Substituting the values, we get:

F_b = 2.45 cm^3 × 1000 kg/m^3 × 9.81 m/s^2 = 24.0 mN

Now, let's assume that the lead weight has a volume V_lead and a mass m_lead. When attached to the bottom of the float, the buoyant force acting on the combination of float and lead weight will still be equal to the weight of water displaced by them. The weight of the combination of float and lead weight can be written as:

W = m_lead × g + m_float × g

where m_float is the mass of the float.

Since the float is half submerged, the buoyant force acting on the combination of float and lead weight is half the weight of the combination. Therefore, we can write:

(1/2) × W = V_disp × ρ_water × g

Substituting the values and solving for m_lead, we get:

m_lead = [(1/2) × F_b - m_float × g] / g

m_lead = [(1/2) × 24.0 × 10^-6 N - 2.35 × 10^-3 kg × 9.81 m/s^2] / 9.81 m/s^2

m_lead = 1.13 × 10^-3 kg

According to the theory of relativity, length measurements depend on the relative motion of the observer and the object being measured. In this case, the observer on the space station measures the length of a meterstick inside a passing spaceship, which means that the meterstick is moving relative to the observer.

Let us assume that the observer on the space station measures the meterstick to be 0.7 m long. This measurement corresponds to the proper length of the meterstick, which is the length of the meterstick as measured by an observer who is at rest relative to the meterstick.

Now, let us consider an observer on the spaceship. According to the theory of relativity, the length of the meterstick as measured by the observer on the spaceship will be shorter than the proper length of the meterstick, due to the relative motion between the observer and the meterstick.

The relationship between the length of the meterstick as measured by the observer on the spaceship (L') and the length of the meterstick as measured by the observer on the space station (L) is given by the Lorentz contraction formula:

L' = L / γ

where γ is the Lorentz factor, which is given by:

γ = 1 / sqrt(1 - v^2/c^2)

where v is the relative velocity between the observer on the spaceship and the meterstick, and c is the speed of light.

Since the meterstick is moving relative to the observer on the space station, we can assume that the relative velocity between the observer on the spaceship and the meterstick is equal to the velocity of the spaceship relative to the space station. Let us assume that the velocity of the spaceship relative to the space station is v = 0.8c, where c is the speed of light.

Plugging in the values for L and v, we get:

γ = 1 / sqrt(1 - 0.8^2) = 1.67

L' = L / γ = 0.7 / 1.67 = 0.42 m

a) Using axes 0xy, we can resolve the forces into their x and y components:

[tex]$\Sigma F_x = mgsin\theta - F_{friction} = ma_x$[/tex]

[tex]$\Sigma F_y = mgcos\theta - N = ma_y$[/tex]

where m is the mass of the block, g is the acceleration due to gravity, θ is the angle of the slope, F_friction is the force of sliding friction, N is the normal force, and a_x and a_y are the x and y components of acceleration, respectively.

We can then solve these equations for a_x and a_y:

[tex]$a_x = gsin\theta - \frac{F_{friction}}{m}$[/tex]

[tex]$a_y = gcos\theta - \frac{N}{m}$[/tex]

Since the block is only moving in the x direction, we can focus on the x component of motion. We know that the acceleration in the x direction is given by a_x, so we can integrate twice to find the position x as a function of time t:

[tex]$x = x_0 + v_0t + \frac{1}{2}a_xt^2$[/tex]

where x_0 is the initial position, v_0 is the initial velocity (which is zero in this case), and t is the time since release.

To find the time it takes for the block to reach the bottom of the slope, we need to find the value of t that corresponds to the position x = L, where L is the length of the slope. We can rearrange the equation above to solve for t:

[tex]$t = \sqrt{\frac{2(L-x_0)}{a_x}}$[/tex]

b) Using axes Ox'y', we can resolve the forces into their x' and y' components:

[tex]$\Sigma F_x' = F_{gravity}sin\theta - F_{friction} = ma_x'$[/tex]

[tex]$\Sigma F_y' = F_{gravity}cos\theta - N = ma_y'$[/tex]

where F_gravity is the force of gravity acting on the block and a_x' and a_y' are the x' and y' components of acceleration, respectively. We can then solve these equations for a_x' and a_y':

[tex]$a_x' = \frac{F_{gravity}}{m}sin\theta - \frac{F_{friction}}{m}$[/tex]

[tex]$a_y' = \frac{F_{gravity}}{m}cos\theta - \frac{N}{m}$[/tex]

Again, since the block is only moving in the x' direction, we can focus on the x' component of motion. We know that the acceleration in the x' direction is given by a_x', so we can integrate twice to find the position x' as a function of time t':

[tex]$x' = x_0' + v_0't' + \frac{1}{2}a_x't'^2$[/tex]

where x'_0 is the initial position (which is zero in this case), v'_0 is the initial velocity (which is also zero), and t' is the time since release.

To find the time it takes for the block to reach the bottom of the slope, we need to find the value of t' that corresponds to the position x' = L. We can rearrange the equation above to solve for t':

[tex]$t' = \sqrt{\frac{2L}{a_x'}}$[/tex]

We can see that the final answer obtained using axes 0xy and axes Ox'y' is the same.
