This ain’t the place, bud. If you have a QUESTION, then you can post it here.
Helium is lighter than air from the lungs.
Explanation:
A balloon filled with the air from lungs will sink to the ground but a balloon filled with Helium floats because helium is lighter than air.
Air is a mixture of many gases.
The air from the lungs is predominantly made up of carbon dioxide and water vapor.
- Gram per mole of carbon dioxide is 44. Water vapor is 18.
- Compared to helium which is 4, we see that the gas is lighter.
- Since the gas is lighter, it will float in air.
- The main component of air around us is nitrogen gas with a gram per mole of 28.
- A balloon filled with more of air from the lungs weigh more than that will filled air around and even far more than helium gas.
- This will cause a helium filled balloon to float.

Answer:
the equations of motion can be separated into an equation that depends on a single variable.
Explanation:
he one-dimensional kinematics equations can be applied to two-dimensional systems because we can write the equations in such a way that each one of them depends on variables in a single dimension plus time, which, because it is a scalar, can be used in all dimensions.
A mathematical way of saying this is that the equations of motion can be separated into an equation that depends on a single variable.
The throttle regulates the power and/or of the engine. If the operator will release the throttle lever, the PWC will remain going straight ahead. Even if the operator will attempt to go right, the PWC will continue to go forward.
Answer:
Pluto revolves around sun with constant speed in a circular orbit, so it is an example of uniform circular motion.
