Answer:
a useful sporting analogy ... Teachers of science routinely use analogies to help ... balls over the bar and you will probably find that.
Answer:
529.15 m/s
Explanation:
h = Maximum height = 70000 m
g = Acceleration due to gravity = 2 m/s²
m = Mass of sulfur
As the potential and kinetic energies are conserved

The speed with which the liquid sulfur left the volcano is 529.15 m/s
Weight is the measurement of the pull of gravity on an object, while mass is the measurement of the amount of matter that an object contains.
Mirrors don't cause refraction.
A convex mirror could cause parallel rays to REFLECT away from each other.
A boiling pot of water (the water travels in a current throughout the pot), a hot air balloon (hot air rises, making the balloon rise) , and cup of a steaming, hot liquid (hot air rises, creating steam) are all situations where convection occurs.
