The velocity of the boat after the package has been thrown is 0.353 m/s.

The velocity of the boat can be determined using the conservation of momentum principle.

The principle of the total momentum of an isolated system remains constant if no external forces act on it.

In this scenario, the initial total momentum of the child-boat system is zero (since the boat was originally at rest), and the final total momentum must be equal to the initial total momentum.

The momentum of the package before it was thrown is

m * v = 10 kg * 3 m/s = 30 kg m/s,

where m is the mass of the package and v is its velocity. After the package has been thrown, the momentum of the system is

(75 kg + 10 kg) * Vb = 85 kg * Vb.

85 kg * Vb = 30 kg m/s

Vb = 30 kg m/s / 85 kg = 0.353 m/s.

The correct option is B, The fact that we always see the same face of the Moon tells us that the Moon rotates with the same period that it orbits Earth.

The Moon rotates on its own axis in a process known as rotation. Like most celestial bodies, the Moon rotates in a counterclockwise direction when viewed from above its north pole. This means that as the Moon orbits the Earth, the same side of the Moon always faces us. This phenomenon is known as synchronous rotation, and it occurs because the Moon's rotation period is almost exactly the same as its orbital period around the Earth.

The Moon's rotation is not a perfect sphere, however, and it has a slight bulge at the equator. This is due to the gravitational pull of the Earth, which has caused the Moon to become slightly deformed over time. The Moon's axial tilt is also very small, which means that its poles are nearly perpendicular to its orbital plane.

The Laplace transfer function of the given electrical circuit is H(s) = V(L) / V(in) = sL / (R + sL + 1/(sC)). When we replace the Laplace variables with the number 2, the function becomes H(2) = 2L / (R + 2L + 1/(2C)).

In an electrical circuit with resistance (R), inductance (L), and capacitance (C), we can use Laplace impedance analysis to find the transfer function relating the input voltage V(in) and the voltage drop across the inductor V(L).

The Laplace impedance of a resistor is R, of an inductor is sL, and of a capacitor is 1/(sC), where s is the Laplace variable. In a series circuit, the total impedance is the sum of the individual impedances. The transfer function is the ratio of the output voltage V(L) to the input voltage V(in).

By analyzing the electrical circuit with Laplace impedance analysis,

we find the transfer function

H(s) = V(L) / V(in)(s) = sL / (R + sL + 1/(sC)).

When the Laplace variable is replaced with the number 2, the function becomes

H(2) = 2L / (R + 2L + 1/(2C)).

The star is moving away from Earth at a velocity of 1.8 x 106 m/s.

The Doppler Effect describes the shift in wavelength of a wave when the source is moving in relation to the observer. The shift can be observed in sound waves, light waves, and other waves.

The Doppler Effect can be used to determine the velocity of objects moving away from an observer, as in the case of stars moving away from Earth.

The velocity of a star moving away from Earth can be determined using the equation:

v = Δλ/λ x c, Where v is the velocity of the star, Δλ is the shift in wavelength of the spectral line, λ is the wavelength of the spectral line measured in the lab on Earth, and c is the speed of light (3.00 x 108 m/s).

In this case, the shift in wavelength of the spectral line is Δλ = 500.3 nm - 500 nm = 0.3 nm.

The wavelength of the spectral line measured in the lab on Earth is λ = 500 nm.

Plugging in these values to the equation above: v = Δλ/λ x cv = (0.3 nm / 500 nm) x (3.00 x 108 m/s) = 1.8 x 106 m/s.

Therefore, velocity of star 1.8 x 106 m/s.

The force exerted by the connecting cord on body P will be less than F, but not zero.

The magnitude of the force exerted by the connecting cord on body P will be D) less than F but not zero. This is because as the force F is applied to body Q, it accelerates to the right and pulls body P along with it due to the connecting cord. However, since the mass of body P is greater than that of Q, it will experience a smaller acceleration than Q. Force is a physical quantity that describes the influence that one object exerts on another. It can be defined as a push or a pull on an object that causes it to accelerate, change direction, or deform. Force is typically measured in units of newtons (N) or pounds (lbs).

Explanation:

Question says , the height of the student = 4 feet,

Depth of the pool( in feet ) be x ( say ) which is less than  4 feet,

Clearly, the depth of the pool < height of the student,

This means, if the student goes for swimming in the pool, however he does not know swimming, he will not be drowned until he is suffering from an injury or external force.

Part A: The maximum emf induced in the coil can be calculated using the formula:

Emax = -N * ΔΦ/Δt

Where:

Emax is the maximum emf induced,

N is the number of turns in the coil, and

ΔΦ/Δt is the rate of change of magnetic flux.

In this case, since the self-inductance of the coil is given, we can use the equation:

Emax = -L * (dI/dt)

Given that the self-inductance L is 7.50 mH and the current varies with time according to i = (680 mA)cos[πt/(0.0250s)], we can differentiate this expression to find dI/dt. Then, we substitute the values into the equation to find the maximum emf induced in the coil.

Part B: The maximum average flux through each turn of the coil can be calculated using the formula:

Φmax = (Emax * Δt) / N

Where:

Φmax is the maximum average flux,

Emax is the maximum emf induced,

Δt is the time interval, and

N is the number of turns in the coil.

Substituting the known values into the equation will yield the maximum average flux through each turn of the coil, expressed in microWebers (μWb).

No, sound cannot undergo total internal reflection at a smooth interface between air and water.

Total internal reflection occurs when a wave traveling in a more optically dense medium encounters a boundary with a less optically dense medium and is reflected back into the more dense medium at a certain angle. This phenomenon is commonly observed with light waves at interfaces between different transparent materials, such as when light travels from water to air or from glass to air.

Sound waves, on the other hand, are mechanical waves that require a medium for propagation. They are compression waves that travel through materials by causing particles in the medium to vibrate. Sound waves do not exhibit total internal reflection at boundaries between different media like light waves do.

When sound waves encounter an interface between air and water, they will undergo partial reflection and refraction. Some of the sound energy will be reflected back into the original medium (air) and some will be transmitted and refracted into the second medium (water). The amount of reflection and refraction depends on factors such as the angle of incidence and the acoustic impedance of the materials.

Therefore, sound waves do not undergo total internal reflection at a smooth interface between air and water, regardless of the medium in which they are originally traveling.

Amir has traveled 245.072 meters up the slope when they pass.

For Amir:

v = u + at

s = ut + 1/2 at^2

where

u = 22.0 km/h = 6.11 m/s (initial velocity)

a = -0.250 m/s^2 (deceleration)

v = 0 m/s (final velocity when Amir and Becky pass)

s = 250 m (distance Amir travels up the slope)

For Becky:

v^2 = u^2 + 2as

where

u = 8.0 km/h = 2.22 m/s (initial velocity)

a = 0.50 m/s^2 (acceleration)

v = 0 m/s (final velocity when Amir and Becky pass)

s = distance Becky travels down from the top

At the instant they pass, both Amir and Becky will have traveled the same distance, so we can equate their respective distances traveled:

250 m + x = s

We can solve for s by first finding the distance Becky travels,

0^2 = (2.22 m/s)^2 + 2(0.50 m/s^2)s

s = (2.22 m/s)^2/(2 x 0.50 m/s^2) = 4.928 m

The spring stiffness, or spring constant, of the given perfect spring is approximately 137.9623 N/m. This means that for every meter of extension, the spring will exert a force of 137.9623 N.

This value was obtained by applying Hooke's Law and calculating the ratio of the change in force to the change in extension using two data points from the table.

To determine the spring stiffness, we need to calculate the spring constant (k) using Hooke's Law, which states that the force applied on a spring is directly proportional to the extension it undergoes.

Hooke's Law can be represented as F = kx, where F is the applied force and x is the extension of the spring.

In the given table, we have the applied forces (F) and corresponding extensions (x). We can use any two data points from the table to find the spring constant.

Let's choose the first and last data points from the table:

(x1, F1) = (0.43 m, 59.34 N) and (x2, F2) = (0.96 m, 132.48 N).

Using Hooke's Law, we can calculate the spring constant (k) as follows:

k = (F2 - F1) / (x2 - x1)
  = (132.48 N - 59.34 N) / (0.96 m - 0.43 m)
  = 73.14 N / 0.53 m
  ≈ 137.9623 N/m (rounded to 4 decimal places)

Therefore, the spring stiffness, or spring constant, is approximately 137.9623 N/m.

Hooke's Law is a fundamental concept in physics that describes the relationship between the force applied on a spring and the resulting extension it undergoes.

The formula F = kx represents this relationship, where F is the applied force, k is the spring constant, and x is the extension of the spring.

By using two data points from the table, we can calculate the spring constant by finding the ratio of the change in force to the change in extension.

This calculation allows us to quantify the stiffness of the spring.
