The ocean wave velocity is 5m/s.
What is wave velocity?
Wave speed commonly refers to velocity, but velocity actually means both speed and direction. A wave's velocity is equal to its wavelength times its frequency (the number of oscillations per second) and is independent of its intensity.
When a point in a rigid body oscillates, both transverse waves (waves in which the point oscillates transversely to the direction of travel) and longitudinal waves (waves in which the point oscillates in the same direction as the direction of travel) are emitted at the same frequency. Longitudinal waves are random, with longer wavelengths traveling faster. Seismic waves, therefore, consist of both longitudinal (P, primary) and transverse (S, secondary) waves and travel through the Earth at two velocities.
Wave velocity is related to wavelength and frequency by the following equations:
Velocity = wavelength x frequency
Using the above formula, we can easily calculate the ocean wave velocity as follows:
Velocity = 50 x 0.1
Velocity = 5m/s
From the calculation above, we know that the ocean wave velocity is 5m/s.

How can you determine the qualitative relationship that may exist in a set of
data?
WILL MARK BRAINLEST
Answer:
Qualitative research can identify key variables in which regards as findings. Such findings may put into a conceptual framework or a research framework, later stage, that research framework can be tested via various statistical methods such as correlation, structural equation modelling ect. Because, qualitative research do not prove any significant relationship among variables, but quantitative research do. However, based on data gathered in qualitative research, the researcher can show that there may have some relationships among variables through graphically or by using NVivo qualitative data analysis software.
Explanation:

Explanation:
When an impact causes the car to suddenly change its motion, (D) the people in the car will continue to move in the same direction and at the same speed as before the impact.
What is Newton's first law of motion?
Newton's first law of motion states that Unless influenced by an imbalanced force, a body at rest stays at rest, and a body in motion keeps moving in a straight path at a constant pace. This law is commonly known as law of inertia and the resistance of a body to maintain its state of rest is called inertia of rest, same as, the resistance of a body to maintain its state of motion is called inertia of motion.
When a car is moving with certain speed, the car along with the people inside the car is in inertia of motion. In an event of accident, the car comes in rest in no time but the man in the car is still in inertia of motion. So, his body moves forward in the car which may cause injuries. To prevent such injuries, the people inside a car are advised to use safety belts.
So, correct answer is option (D).

Describe the magnetic field?The magnetic influence on moving electric charges, electric currents and magnetic materials is described by a magnetic field, which is a vector field. A force perpendicular to the charge's own velocity and the magnetic field acts on it when the charge is travelling through a magnetic field. The magnetic field of a permanent magnet pulls on ferromagnetic substances like iron and attracts or repels other magnets. A magnetic field that varies with location will also exert a force on a variety of non-magnetic materials by changing the velocity of those particles' outer electrons.

Not convection because those happen when heat causes a difference in densities, allowing substances to circulate.
a car initially traveling at 60 km/h accelerates at a constant rate of 2.0 m/s2. how much time is required for the car to reach a speed of 90 km/h? quizlet
Time required for the car to reach a speed of 90 km/h is 4.165 seconds.
To solve for time, use the formula for time, t = d/s which means time equals distance divided by speed.4.165 sec
In light of the posed query,
Initial velocity is 60 km/h, which is 60 x 1000 / 36600, or 16.67 m/s.
90 km/h is equal to 901000/3600, or 25.
2 m/s2 for acceleration, or a.
t = time
We are also asked to determine how long it will take the car to
accelerate to its final speed of 90 km/h.
We are aware,
v = u+at
Given the values we receive,
25 = 16.67 + 2t
2t = 25-16.67
2t = 8.33
t = 8.33/2
t = 4.165 sec
Thus, the car will take 4.165 sec to attain the final velocity of 90 km/h if its acceleration is 2 m/s^2 and initial velocity is of 60 km/h.

"El sujeto es emergente de la compleja trama de relaciones vinculares e institucionales que lo determinan. En esa trama, las relaciones tempranas adquieren un lugar fundamental en los procesos de constitución subjetiva" Terigi, Flavia (2010) Sujetos de la Educación. Para el psicoanálisis, ¿cuáles serían esas relaciones tempranas y por qué se afirma que son fundamentales en los procesos de constitución subjetiva?
La respuesta correcta para esta pregunta abierta es la siguiente.
Para el psicoanálisis, las relaciones tempranas son las relaciones a posteriori entre los padres del recién nacido y el bebé mismo. Estas relaciones son fundamentales en los procesos de constitución subjetiva para el discurso parental para entender los aspectos del desarrollo infantil y sus diferentes estados o teorías de desarrollo para ir comprendiendo cada aspecto de la interrelación y el comportamiento entre las partes.
Para el psicoanálisis, el recién nacido está llegando a un núcleo familiar que ya está establecido y se basa en conocimientos, tradiciones y experiencias de los padres que han recibido de generaciones anteriores, y éstas van a influir directamente en la interrelación permanente con los primeros años del crecimiento del bebé.

~AH1807What does a step down transformer change in an alternating current
The step down transformer decrease the incoming current's voltage.
Transformers go with the principle of mutual inductance . A changing magnetic field in one circle of wire actuates an electromotive force (EMF) in an adjoining circle of wire, inductively coupled to the primary. In exceptionally fundamental terms, a transformer comprises two coils of wire with tall shared inductance. These coils are electrically isolated whereas they share a common magnetic circuit. In a step-down transformer, there is a decrease in the incoming current’s voltage, where the primary voltage is the incoming voltage whereas the outgoing voltage is considered the secondary. the second coil has fewer windings than the primary, permitting a decrease in voltage within the exiting electrical stream. The primary winding, which is the primary set of coils, interfaces to an alternating-current voltage source, or primary voltage influx. The secondary coil interfaces to the stack, or secondary voltage outpouring, conveying the electrical control absent from the transformer. The substituting current streaming in at the primary voltage makes a substituting magnetic flux. This actuates a similar current within the secondary coil, making a secondary voltage. Here, the diminished number of windings within the secondary coil successfully diminishes the resultant voltage, subsequently “stepping down” the voltage to a lower value whereas keeping up a steady frequency.

Why do diffraction patterns occur?Diffraction of light, as it is used to describe light, occurs more explicitly when a light wave passes by a corner or via an aperture or slit that is physically
Light is diffracted primarily as a function of wavelength (frequency), amplitude, and slit width. The incident waves must have a larger amplitude than the slit width for any diffraction to take place. Diffraction won't happen if the wave is less than the slit width.
The quantity of diffraction increases with the wave's wavelength. When the gap size is almost equal to the wavelength, the most 2×10 −4 m occurs.
