The period of water waves is 4 seconds. The frequency of water waves is 0.25 Hz. The wave speed is 0.75 m/s.

Period of waves or wave period represents the time taken by the wave to complete one cycle. It is also defined as the time is taken for two successive crests or troughs (one wavelength) to pass through the specific point.

The wave period is measured in seconds. Hence, its unit is seconds (s). The period of a wave is the ratio of the wavelength and velocity. The wave period is inversely proportional to the frequency.

Frequency is defined as the number of waves passes through the medium in a given time.  Frequency equals the number of cycles per second. The unit of frequency is hertz (Hz).

Frequency is inversely proportional to the wave period. If the frequency increases, the wave period decrease, and the wave period increases by decreasing the wave period.

The wave speed equals the product of wavelength and frequency. Wave speed is defined as the distance of wave travels in a given time. The unit of wave seed is m/s.

From the givens,

time = 40 seconds, wavelength = 10m

Wave period = time/wavelength

                     = 40/10

Wave period = 4 seconds.

Frequency = 1 / wave period

                  = 1 / 4

Frequency = 0.25 Hz.

Wave speed = wavelength × frequency

                    = 3×0.25

                    = 0.75 m/s

Wave speed = 0.75 m/s.

Hence, the wave period is 4s, the frequency is 0.25 Hz, and the wave speed is 0.75 m/s.

The denominator is 0, indicating that the final angular speed is undefined in this case. This means that it is not physically possible for the man to reach a point 0 m from the center without any change in the moment of inertia of the system.

To solve this problem, we can apply the principle of conservation of angular momentum. Initially, the angular momentum of the system is given by:

L_initial = I_initial * ω_initial

where L_initial is the initial angular momentum, I_initial is the initial moment of inertia, and ω_initial is the initial angular speed.

When the man walks to a point 0 m from the center, the moment of inertia of the system changes. The new angular momentum can be calculated using:

L_final = I_final * ω_final

where L_final is the final angular momentum, I_final is the final moment of inertia, and ω_final is the final angular speed.

Since angular momentum is conserved, we can equate the initial and final angular momenta:

L_initial = L_final

I_initial * ω_initial = I_final * ω_final

Now, let's calculate the initial and final moments of inertia:

For the initial moment of inertia (I_initial), the man is standing 2.2 m from the axis of rotation. Since the merry-go-round is modeled as a solid cylinder, the moment of inertia of a solid cylinder is given by:

I_initial = (1/2) * m * r^2

where m is the mass and r is the radius. Plugging in the values:

I_initial = (1/2) * 83 kg * (2.2 m)^2

I_initial = 162.86 kg·m^2

For the final moment of inertia (I_final), the man is at a point 0 m from the center. In this case, the moment of inertia can be calculated as:

I_final = m * r^2

Plugging in the values:

I_final = 83 kg * (0 m)^2

I_final = 0 kg·m^2

Now, let's solve for the final angular speed (ω_final):

I_initial * ω_initial = I_final * ω_final

162.86 kg·m^2 * (0.5 rev/s) = 0 kg·m^2 * ω_final

ω_final = (162.86 kg·m^2 * (0.5 rev/s)) / 0 kg·m^2

The box will have the greatest velocity just before striking the ground when it is dropped without initial velocity (i.e. dropped from rest).

This is because the velocity of a freely falling object under the influence of gravity increases with time, following the equation v = gt, where v is velocity, g is the acceleration due to gravity (9.8 m/s^2 on the Earth's surface), and t is time.

The velocity of the box continues to increase as it falls, reaching its maximum just before it strikes the ground.

If the box is given an initial velocity, for example by being thrown, it will still increase in velocity as it falls, but the maximum velocity will be less than if it was dropped from rest.

The final velocity of the box just before striking the ground will depend on the height from which it was dropped and the time taken to fall.

The three characteristics that all the plants most likely share are: have xylem and phloem; lack pollen. Option D.

In seed plants, xylem and phloem are essential vascular tissues responsible for the transport of water, nutrients, and sugars throughout the plant. Xylem transports water and minerals from the roots to the rest of the plant, while phloem carries sugars and other organic compounds from photosynthetic regions to other parts of the plant.

The absence of pollen indicates that these plants do not reproduce through the production and dispersal of pollen grains. Instead, they likely reproduce through other means, such as the production of seeds.

This combination of having xylem and phloem while lacking pollen suggests that the plants in question are likely gymnosperms. Gymnosperms are a group of seed plants that include conifers, cycads, ginkgoes, and others. These plants typically produce seeds that are not enclosed within a fruit, and they rely on other methods such as wind or insects for pollination.

It is important to note that this conclusion is based on the provided information and is subject to change depending on further details about the specific characteristics of the gathered plants. SO Option D is correct.
