Answer:
Hey ! The number of atoms in the reactants must be equal to the number of atoms in the products so
CCl4 ~> C + 2 Cl2
A wave with a height of 5 feet and a wavelength of 15 feet has a wave base of <u>7.5 feet</u>.
A. 7.5 feet
<u>Explanation:</u>
Wave base defines the depth of the water when it is in still condition.
Wave base is half of wavelength.
Wave base = wavelength/2
Given,
Wavelength = 15 feet
So, wave base = 15 feet/2 = 7.5 feet
When the wave height is divided by wavelength then it gives the steepness of the wave.
Therefore, the wave base is 7.5feet.
Yes, sure!
1) Moving Water - Water, when running for a long period of time, can actually start to weather rocks.
2) <span>Ice wedging - Yep, this can cause rocks to weather as well. Water, when being constantly frozen and unfrozen weathers the rock due to the fact that water is able to expand.

3) Plant Roots - Ah, these little nutrient grabbers can certainly weather rocks over periods of time.
4) Winds - Winds can certainly physically weather the rocks, and it's probably the most common way they do.
