Not at all. Density on its own is not sufficient
Global warming, acid rain and general air pollution from car exhaust occurs from burning fossil fuels. The global warming occurs because of a "green house effect" where sunlight is trapped inside our atmosphere due to air pollution. Acid rain occurs when the products of combustion, sulfur dioxide, nitrous dioxide and nitrogen dioxide mix with rain water.
Each of these impacts is very extensive. Each fossil fuel has individual impacts related to their use
L = length of side of square = 0.400 m
d = length of the diagonal
using Pythagorean theorem
d = sqrt(L² + L²)
d = sqrt(2L²)
d = sqrt(2) L
r = distance of each small sphere from the center
from the diagram , we see that
2r = d
hence r = d/2
r = sqrt(2) L/2
r = L/sqrt(2)
moment of inertia is given as
I = m r²
total moment of inertia of four spheres is given as
I' = 4 I
I' = 4 m r²
I' = 4 m ( L/sqrt(2))²
I' = 4 mL²/2
I' = 2 mL²
inserting the values
I' = 2 (0.2) (0.4)²
I' = 0.064 kgm²
Answer:
The question is basically asking you to research a instrument that provides scientific-physical terms like sound waves. It also says to explain how different types of instruments provide different tones.(Hint: Sound waves)
