The observer (point H) must be positioned to the right of the person and to the left of the lamppost, to the left of the person and to the right of the lamppost, or behind the lamppost to see the person obstructed by it.

To determine the possible positions of the observer (point H) relative to the mirror showcase, we need to consider the given information about the position of the person and the lamppost.

If the person is to the left of the lamppost (point C) as seen in the window, then the observer (point H) must be positioned to the right of the person and to the left of the lamppost. This is because the mirror will reflect the image of the person to the right, and the observer must be positioned to the right of the reflected image to see it.

If the person is to the right of the lamppost (point C) as seen in the window, then the observer (point H) must be positioned to the left of the person and to the right of the lamppost. This is because the mirror will reflect the image of the person to the left, and the observer must be positioned to the left of the reflected image to see it.

If the lamppost (point C) obstructs the view of the person as seen in the window, then the observer (point H) must be positioned behind the lamppost, either to the left or to the right of it.

Answer:

0.0124 AU

Explanation:

Ganymede takes 7.15 Earth days to orbit Jupiter. Ganymede is measured to be 7.1 X 10⁻³ AU from Jupiter’s center.

We need to find how far away is Callisto from the center of Jupiter if a second moon of Jupiter, Callisto, takes 16.69 Earth days to orbit Jupiter. Let it is r₂. Using third law of Kepler.

\(T^2\propto r^3\)

i.e.

\((\dfrac{T_1}{T_2})^2=(\dfrac{r_1}{r_2})^3\\\\\dfrac{r_1}{r_2}=(\dfrac{T_1}{T_2})^{2/3}\\\\r_2=\dfrac{r_1}{(\dfrac{T_1}{T_2})^{2/3}}\\\\r_2=\dfrac{7.1\times 10^{-3}}{(\dfrac{7.15}{16.69})^{2/3}}\\\\r_2=0.0124\ \text{AU}\)

So, Callisto is 0.0124 AU from the center of the Jupiter.

Answer:

The greater the density of a medium, the slower the speed of sound. This observation is analogous to the fact that the frequency of a simple harmonic motion is inversely proportional to m, the mass of the oscillating object.

Air molecules have more energy at higher temperatures, which means they vibrate faster. This allows the sound waves to also travel faster because they are propelled by collisions between the molecules

A wave is a disturbance that moves or travels through a medium such as air, water, or even space without causing any actual transfer of the medium from one point to another. It transfers energy from a source to a receiver, where it can be sensed or detected, but it does not transport any actual material.

A wave can be described by its amplitude, wavelength, frequency, and period. The distance between two consecutive peaks or troughs in a wave is referred to as its wavelength. The time required for one complete wave cycle to occur is referred to as the wave's period. The energy carried by a wave is proportional to its amplitude, which is the distance between the wave's maximum displacement and its equilibrium position. Waves can be classified into two categories: transverse and longitudinal waves.

The answer is high susceptibility;  low retentivity. Iron is good for creating solenoids because its high susceptibility and low retentivity allow it to be magnetized and demagnetized quickly.

Its high compliance and low iron retention make it a good choice for making magnetic coils. These properties make iron easier to magnetize and demagnetize, making it an ideal material for making magnetic circuits and other magnetically sensitive devices.

Iron magnetizes faster, but loses its magnetism once the inductor magnet is removed. For example, soft iron should have high flexibility but low retention. This property of soft iron is very useful for making temporary electromagnets, where we need strong but temporary magnets.

The magnitude of their overall displacement is approximately 29.7 meters.

To find the magnitude of their overall displacement, we need to find the net displacement, which is the straight-line distance from their starting point to their final point.

We can use the Pythagorean theorem to find the net displacement. Let's break down their movements in terms of their x and y components:

Moving 3 meters South gives us a displacement of -3 meters in the y direction.

Turning right and walking 17 meters West gives us a displacement of -17 meters in the x direction.

Turning right again and walking 24 meters North gives us a displacement of +24 meters in the y direction.

Turning left and walking 38 meters East gives us a displacement of +38 meters in the x direction.

To find the net displacement, we can add up the x and y components separately:

Net x displacement = -17m + 38m = 21m to the right (east)

Net y displacement = -3m + 24m = 21m to the north

Using the Pythagorean theorem, we can find the magnitude of the net displacement:

Magnitude of net displacement = sqrt(21² + 21²) = sqrt(882) ≈ 29.7 meters

Therefore, the magnitude of their overall displacement is approximately 29.7 meters.

Using the concept of direction, we got the mountain behind me when we turn West.

A mountain is an elevated portion of Earth's crust, generally with steep sides that show significantly exposed bedrock. Although definitions vary, a mountain may differ from plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 meters (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in the mountain ranges.

Mountains are formed through a tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, slumping, and other forms of mass wasting, as well as through erosion by rivers and the glaciers.

Explanation:

The power generated by the sprinter is 490 J/s.

We need to know power first to solve this problem. Power is a unit that measures how much energy is released in one second. Power can be determined as

P = W / t

where P is power, W is work and t is time.

The work can be determined as the change of kinetic energy

W = 1/2 . m . (v1² - vo²)

where m is the mass and v is velocity.

From the question above, we know that:

m = 60 kg

vo = 0 m/s

v1 = 7 m

t = 3 s

By substituting the parameters, we get

P = W / t

P = 1/2 . m . (v1² - vo²) / 3

P = 1/2 . 60 . (7² - 0²) / 3

P = 490 J/s

Hence, the power generated by the sprinter is 490 J/s.

The position of the mass as a function of time is x(t) = 5 * sin(4t).

To find the position of the mass as a function of time, we can use Newton's second law of motion, which states that the sum of the forces acting on an object is equal to the mass of the object multiplied by its acceleration.

The equation of motion for a mass-spring system is given by:

m * d^2x/dt^2 + k * x = F(t)

Where:

m is the mass connected to the spring,

x is the position of the mass,

t is time,

k is the spring constant,

F(t) is the applied force as a function of time.

In this case, the mass m is 2 kg, the spring constant k is 32 N/m, and the applied force is given by F(t) = 128sin(4t).

Plugging these values into the equation of motion, we get:

2 * d^2x/dt^2 + 32 * x = 128sin(4t)

Rearranging the equation, we have:

d^2x/dt^2 + 16 * x = 64sin(4t)

This is a second-order linear ordinary differential equation with constant coefficients. To solve this equation, we can assume a solution of the form x(t) = A * sin(ωt + φ), where A is the amplitude, ω is the angular frequency, and φ is the phase angle.

Differentiating x(t) twice with respect to time, we have:

dx/dt = A * ω * cos(ωt + φ)

d^2x/dt^2 = -A * ω^2 * sin(ωt + φ)

Substituting these derivatives into the equation of motion, we get:

-A * ω^2 * sin(ωt + φ) + 16 * A * sin(ωt + φ) = 64sin(4t)

Equating the terms with sin(ωt + φ) on both sides, we have:

-A * ω^2 + 16 * A = 64

Simplifying the equation, we get:

16A - Aω^2 = 64

We know that the angular frequency ω is related to the spring constant k and the mass m as ω = √(k/m). Substituting the given values, we have:

ω = √(32 N/m / 2 kg) = √(16) = 4

Plugging ω = 4 into the equation, we get:

16A - 16 = 64

Solving for A, we have:

16A = 80

A = 5

Therefore, the amplitude A is 5.

Now, we can write the position function as:

x(t) = 5 * sin(4t + φ)

To find the phase angle φ, we can use the initial conditions. At t = 0, the spring is initially at rest and hanging at its equilibrium position, which means x(0) = 0.

Plugging this into the position function, we have:

0 = 5 * sin(0 + φ)

Since sin(0) = 0, we get:

0 = 0 + φ

φ = 0

Therefore, the phase angle φ is 0.

Finally, the position of the mass as a function of time is:

x(t) = 5 * sin(4t)
