They differ because they are transverse wave. That is their direction of travel is perpendicular to its vibrations.
It is customary to work in SI units.
Calculate the volume of the concrete.
V = 3.7*2.1*5.8 cm³ = 45.066 cm³ = 45.066 x 10 ⁻⁶ m³
The mass is 43.8 g = 43.8 x 10⁻³ kg
The density is mass/volume.
Density = (43.8 x 10⁻³ kg)/(45.066 x 10⁻⁶ m³) = 971.9 kg/m³
Answer: 971.9 kg/m³
The answers is
D. The acid creates cracks in the rocks, which
allow air to circulate through the rock,
causing it to weather
Is the variable you change, independent, I, something I change.
