Have you ever heard this phrase, "What weighs more, a ton of feathers, or a ton of lead?" The answer is, they weigh the same, however the ton of feathers takes up more space than the ton of lead. So to answer your question, the answer is yes, and no. Depending on what the substance is will determine your answer. I hope that i helped.
Answer:
a) 0.00996 m
b) 109090909 Pa
Explanation:
Unit conversions:

1.2 mm = 0.0012 m
8.5 kN = 8500 N
If the 2.2m rod cannot stretch more than 0.0012 m, its maximum strain is

With elastic modulus being E = 200 GPa, then its maximum stress must be

Knowing the tension force being F = 8500 N, we can calculate the appropriate cross section area

And its corresponding diameter is




4.98 kJ/mol would be the answer I believe :) hope this helped
Answer:
Now you know gravity is a major force in the universe. It keeps us from floating away, controls the ocean's tides, guides plant growth, keeps Earth and other planets in orbit.

Answer:
An incident ray is a ray of light that strikes a surface. The angle between this ray and the perpendicular or normal to the surface is the angle of incidence.
The reflected ray corresponding to a given incident ray, is the ray that represents the light reflected by the surface. The angle between the surface normal and the reflected ray is known as the angle of reflection. The Law of Reflection says that for a specular (non-scattering) surface, the angle of reflection always equals the angle of incidence.
