Answer:
Wavelength = 5 * 10^{-11} meters
Explanation:
Given the following data;
Frequency = 6.0 x 10^18 Hz
Speed = 3 * 10⁸ m/s
To find the wavelength of the wave;
Mathematically, the wavelength of a wave is given by the formula;

Substituting into the formula, we have;

Wavelength = 5 * 10^{-11} meters
A) F = gravitational force
b) G = universal gravitational constant (6.67 × 10-11 N-m2/kg2)
c) m1 = mass of the body 1
d) m2 = mass of body 2
e) r = radius or distance between the two bodies.

The rock had to have undergone chemical weathering due to its change in mineralogical and chemical composition of the rock.
Or
Chemical weathering is when the acid from rain starts to burn through rocks and damage them
