You are standing on the beach counting waves. you use the pier to estimate that there is 5 m between wave crests and you measure that a wave takes 2 seconds to pass your location. what is the speed of the wave?

2.5 m/s

Explanation:

In this problem, we know:

is the wavelength of the wave (distance between two successive crests)

is the period of the wave (the time it takes a wave to pass the location)

From the period, we can find the frequency of the wave:

And now we can find the speed of the wave by using the following equation:

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..

the simple machine has three main features. they are:

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are

x : load

y: fulcrum

z: lever
