The concept required to solve this problem is related to the wavelength.
The wavelength can be defined as the distance between two positive crests of a wave.
The waves are in phase, then the first distance is

And out of the phase when

Thus the wavelength is

Here,
Wavelength
If we rearrange the equation to find it, we will have



Therefore the wavelength of the sound is 20cm.
<h2>
Height of bridge is 83.66 m</h2>
Explanation:
We have equation of motion s = ut + 0.5 at²
Initial velocity, u = 25.3 m/s
Acceleration, a = 9.81 m/s²
Time, t = 2.29 s
Substituting
s = ut + 0.5 at²
s = 25.3 x 2.29 + 0.5 x 9.81 x 2.29²
s = 83.66 m
Height of bridge is 83.66 m
Answer:
deposited, sedimentation
Explanation:
Rivers pick up pieces of sediments then deposit them elsewhere.
Hope I helped. :)
Answer:
Normalization is a systematic approach of decomposing tables to eliminate data redundancy. It is a multi-step process that puts data into tabular form, removing duplicated data from the relation tables.
Explanation:
<h2>Camels have 12 humps and lives at the North Pole </h2>
Six lost camels has 12 humps and lives at the north pole. The reason is that animal which possess hump are camels and they live at the north pole. Camel is used for travel purpose and for transfer goods from one place to another place.
Basically, a camel's hump is a large heap of fat. In a normal camel hump can be of 80 pounds that is equal to 35 kilograms on the scale. Human and many animals stocks their fat blended within the muscle tissue or beneath the skin layers. Camels are the sole living organism with a hump on its back.
