-- If doubling one quantity causes the other one to also double, the two quantities
are directly proportional. Their ratio is always the same.
-- If doubling one quantity causes the other one to drop by half, the two quantities
are inversely proportional. Thier product is always the same.

Is acceleration directly proportional to mass or is it inversly proportional to mass?
Depends what u mean by that. If it is free falling it would obviously be accelerating at 9.8m/s^2. If there is an incline then it depends. I believe acceleration is directly proportional to velocity though.
What gas expands when heated?
all gases. The volume of a gas is directly proportional to the temperature, and inversely proportional to pressure. Maybe you mean air, but air is a mixture of gases
What does the energy of an em depend on?
If you mean electromagnetic waves, the energy per photon is directly proportional to the frequency (and therefore inversely proportional to the wavelength). The total energy of the wave, of course, can be just about anything.
What does it mean to say momentum is directly proportional to mass and velocity?
Being proportional means that if you change one by a given factor, the other will change by that factor as well. Being proprtional to both means it is proportional to their product, i.e. momentum equals mass times velocity, p = mv.
What happens to the volume of a sound wave as its amplitude decrease?
You mean by the word 'volume' the intensity of sound wave. Intensity is directly proportional to the square of the amplitude.
What does indirectly mean in science?
it means not directly
What does it mean when something is directly proportional?
Directly proportional means that both variables increase or decrease at the same time.
What does directly or indirectly mean?
Directly means following a straight/shortest path. Indirectly means not following a straight/shortest path.
Is slalom skiing directly or indirectly?
If you mean contacting with the gates yea

The strength of an electrical signal is directly proportional to its frequency?
Hard to know what you mean by "strength". If you mean power, then the answer is no.
Is mean directly proportional to standard deviation?
No. Not at all. Whoever told you that fails statistics forever.
What does the term biomass fuel mean?
Organic matter convertible into heat, directly by burning or indirectly by biogastification
What gas expands when heated?
all gases. The volume of a gas is directly proportional to the temperature, and inversely proportional to pressure. Maybe you mean air, but air is a mixture of gases
What does inversely and directly proportional mean?
Inversely proportional means that one variable goes up while the other goes down. Directly proportional means that both variables increase or decrease at the same time. ex: The volume of a gas at constant pressure is inversely proportional to gas pressure, thus this means that as pressure increases, the volume of the gas will decrease. ex: The volume of a fixed amount of gas is directly proportional to absolute pressure, thus this means that when you heat a gas the volume also increases.
What does the energy of an em depend on?
If you mean electromagnetic waves, the energy per photon is directly proportional to the frequency (and therefore inversely proportional to the wavelength). The total energy of the wave, of course, can be just about anything.
How do the changes in mass and distance effect the force of gravity?
Bigger masses mean a bigger force of gravity. Bigger distances mean smaller forces. Mathematically, the force is directly proportional to the product of the masses, and inversely proportional to the square of the distance.
