Answer:

Wave X has a shorter wavelength.

Explanation:

It is given that, two sound waves (wave X and wave Y) are moving through a medium at the same speed.

Speed of a wave is given by :

v=\nu\times \lambda

Where,

\nu is frequency

\lambda is wavelength

The relation between the frequency and the wavelength is inverse. Wave X has greater frequency than Y, then wave X has a shorter wavelength.

Hence, the correct option is (B) "has a shorter wavelength".

Water waves that you might see at the beach move in circular or elliptical paths. What type of mechanical waves are water waves?
vazorg [7]

To find:

Which type of mechanical wave is a water wave?

Explanation:

The water wave is a combination of longitudinal and transverse waves. They are a type of wave called surface waves. The surface waves are the waves that transmit energy in the interface between two mediums.

Final answer:

Thus the correct answer is option C.

A block with mass 0.470 kg sits at rest on a light but not long vertical spring that has spring constant 85.0 N/m and one end on
a_sh-v [17]

Answer: elastic potential energy = 20.27 J

Explanation:

Given that the

Mass M = 0.470 kg

Height h = 4.40 m

Spring constant K = 85 N/m

The maximum elastic potential will be equal to the maximum kinetic energy experienced by the block.

But according to conservative of energy, the maximum kinetic energy is equal to the maximum potential energy experienced by the block of mass M.

That is

K .E = P.E = mgh

Where g = 9.8m/s^2

Substitutes all the parameters into the formula

K.E = 0.470 × 9.8 × 4.4

K.E = 20.27 J

Where K.E = maximum elastic potential energy stored in the spring during the motion of the blocks after the collision which is 20.27J.

How could you use the physical properties of melting poin and boiling point to identify a substance?
Vanyuwa [196]

By comparing the melting and the boiling points of the test substance to that of the substances that are recorded in the literature, we can be able to obtain the identity of a substance.

<h3>What is melting point?</h3>

The melting point is the point at which the solid would change to liquid. The boiling point is the point at which a liquid would change to gas. Now we know that the melting and the boiling point of a signature of a compound and can be used to identify a pure substance.

Hence, by comparing the melting and the boiling points of the test substance to that of the substances that are recorded in the literature, we can be able to obtain the identity of a substance.
