Answer:

260 Hz

Explanation:

The frequency of a sound wave is  defined as the number of oscillation which is given in cycles per time. Frequency (f) is given  by the formula ;

f = \frac{1}{T} and it is measured in Hertz(Hz)

Given that;

a vibration is caused by a struck string in piano at  260 cycles and Time (T) = 1 seconds

Frequency (f) can be determined as; 260 cycles × 1 seconds

= 260 Hertz (Hz)

Hence, the frequency of the sound wave is 260 Hertz (Hz).

Which statement describes a surface wave?
katen-ka-za [31]
A surface wave is a wave that travels along the surface of a medium. The medium is the matter through which the wave travels. Ocean waves are the best-known examples of surface waves. They travel on the surface of the water between the ocean and the air. (According to ck12.org)

So your answer would be A!

A 5.0 kg wooden block is in free fall at 10 m/s. What is the Kinetic Energy for the wooden block?
andre [41]

Answer:

250 J

Explanation:

Apply the formula:

K = 1/2.m.v²

K = 1/2.5.10²

K = 1/2.5.100

K = 5.50

K = 250 Joules

But, remember that if the speed is accelerating or not, if it is, then we need to know the point in time that the question is asking for the Kinetic Energy.

In this case, I think it is just a constant speed.
