Its C because if it is a low frequency it will not change much so it will be a longer wavelength and the higher the frequency the shorter the wavelength
the answer is concave lens
The movement of tectonic plates can cause earthquakes. Some can be major and some can be minor. Both can affect non-earthquake proof buildings though
Answer:
The mass of object is calculated as 5.36 kg
Explanation:
The known terms to find the mass are:
acceleration of object (a) = 22.35 
Force exerted (F) = 120N
mass of an object (m) = ?
From Newton's second law of motion;
F = ma
or, 120 = m × 22.35
or, m=
kg
∴ m = 5.36 kg
