Chemical weathering uses water, Mechanical weathering uses water too.
add some choices bro
Answer: Option (b) is the correct.
Explanation:
It is known that energy is directly proportional to frequency.
Mathematically,
or, E = ............ (1)
where, E = energy
h = Plank's constant
= frequency
This relation shows that higher is the energy then more will be the frequency of electrmagnetic radiation.
Also, ......... (2)
where, c = speed of light
= wavelength
Therefore, substituting value of from equation (2) into equation (1) as follows.
E =
E =
This relation shows that higher is the energy then lower will be the wavelength.
Thus, we can conclude that as the energy of a photon increases, its frequency decreases, is incorrect statement.
Answer:
Proust concluded that the elements in a chemical compound always present in the same ratio by mass.
Explanation:
In English, this finding became known as the Law of Definite Proportions.
For example, a 100 g sample of copper(II) sulfide always contains 66.46 g of copper and 33.54 g of sulfur.
The mass ratio in CuS is
Cu/S = 66.46/33.54 = 1.982/1
