Well, first, let's recognize that there is no such thing as a force that is
balanced or unbalanced.
When we say that a group of two or more forces is balanced, we mean
that when you add up all the magnitudes and directions of the forces, the
whole group adds up to zero, so they have the same net effect as if there
were no force at all.
Answer:
For a gas held at constant temperature, we can apply Boyle's law, which states that the product between the gas pressure and its volume is constant:
where
P is the pressure
V is the volume
As we see from the equation, P and V are inversely proportional to each other: this means that when the volume is decreased, the pressure increases, and vice-versa. The reason for that is that when the volume is decreased, the gas is compressed, so the molecules of the gas come closer to each other, so they collide more frequently with the wall of the container, exerting therefore a greater pressure.
The correct option is D.
Absorbents are products which are principally designed to soak up spills and leaks. There are different types of absorbents and they are designed to absorb different substances. The absorbents are typically equipped with specific features which make them suitable for absorbing specific substances. Thus, one can not mixed up different absorbent for use. Most absorbents are designed to soak up oil spills.
Answer:
(4) Elastomers
Explanation:
Substances which can be elastically stretched to large value of strain are called elastomers.
