The speed of a wave can be calculated using this formula:

v = f x λ

Where:

v is the wave speed in metres per second, m/s

f is the frequency in hertz, Hz

λ (lambda) is the wavelength in metres, m

Calculation:

Given:

f = 20 Hz

λ = 100m

Using the equation:

v = f x λ

v = 20 x 100

v = 2000 m/s

Therfore, the speed of the wave is 2000 m/s

Drag the tiles to the correct boxes to complete the pairs.
iragen [17]

Answer:

Solid:- Particles vibrate in a rigid structure and do not move relative to their neighbors.

Liquid:- It takes the shape of its container but keeps a constant volume.

Gas:- Particles move rapidly and independently of each other.

Plasma:- It is the most common state of matter in the universe.

Explanation:

Solids are one of the three states of matter and, unlike liquids or gases, they have a definite shape that is not easy to change. Different solids have particular properties such as stretch, STRENGTH, or hardness that make them useful for different jobs.

A liquid is a nearly incompressible fluid that conforms to the shape of its container but retains a (nearly) constant volume independent of pressure

Gas is a state of matter that has no fixed shape and no fixed volume. Gases have lower density than other states of matter, such as solids and liquids. When more gas particles enter a container, there is less space for the particles to spread out, and they become compressed. The particles exert more force on the interior volume of the container.

A plasma is a gas that has been energized to the point that some of the electrons break free from, but travel with, their nucleus.
