Answer:
It's helps Emily became when she swims her hair is not in the way creating friction and making her swim faster. friction acts between two metals blocks that slide past each other.

Answer:
"How does the volume of a gas kept at constant pressure change as its temperature is increased?"
Explanation:
One possible question can be:
"How does the volume of a gas kept at constant pressure change as its temperature is increased?"
The answer to this question is contained in Charle's law, which states that for a gas at constant pressure, the volume of the gas is proportional to its absolute temperature:
Or also written as
By looking at this equation, we can find immediately the answer to our question: as the (absolute) temperature of the gas increases, the volume increases as well, by the same proportion.
Speed is a derivation of energy (thats what my science teacher said)
Use equation, force×distance=work done(a form of energy).
force=work done÷distance= 2240÷40=56N
In surface waves, particles of the medium undergo a circular motion. They are neither longitudinal nor transverse, for in longitudinal and transverse waves, all the particles in the entire bulk of the medium move in a parallel and a perpendicular direction, respectively, relative to the direction of energy transport.
