If a wave is traveling at 200 m/s and it’s wavelength is 0.5 meters , what is the frequency of the wave
Mrrafil [7]

Answer:

400 Hz

Explanation:

The frequency of a sound wave is found by the velocity/wavelength.  Therefore, f = v/wavelength = (200 m/s)/(0.5 m) = 400 Hz

I hope this helps! :)

What is kinetic friction?
Lunna [17]

Answer:

Kinetic friction is an inhibitory force that is present when a body or object begins to move. It should be noted that this force is in the opposite direction to the movement of the body that slides with respect to a surface and parallel to that surface.

In addition, this friction varies according to the surface characteristics and the material properties of the bodies that slide in this surface. Being quantified by the coefficient of kinetic friction \mu_{K}, which is dimensionless.

The rotational kinetic energy term is often called the kinetic energy in the center of mass, while the translational kinetic ene
weqwewe [10]

Answer:

C

Explanation:

The total kinetic energy is the sum of the kinetic energy in the center of mass (Rotational Kinetic energy) plus the kinetic energy of the center of mass( Translational Kinetic Energy).

The formula

K_{tot} = K_{t} +K_{r}  is applicable only when

The moment of inertia must be taken about an axis through the center of mass.

What are em waves expain in details
Tresset [83]
Electromagnetic waves or EM waves are waves that are created as a result of vibrations between an electric field and a magnetic field. ... They are hence known as 'electromagnetic' waves. The electric field and magnetic field of an electromagnetic wave are perpendicular (at right angles) to each other.

Hope this helps.

A girl is bouncing on a trampoline where is her gravitational potential energy a maximum and where is her kinetic energy maximum
Stella [2.4K]

Answer:

When you jump down, your kinetic is converted to potential energy of the stretched trampoline. The trampoline's potential energy is converted into kinetic energy, which is transferred to you, making you bounce up. At the top of your jump, all your kinetic energy has been converted into potential energy. Right before you hit the trampoline, all of your potential energy has  been converted back into kinetic energy. As you jump up and down your kinetic energy increases and decrease.
