<span>So the question is what gases form the atmosphere of Uranus. So Uranus and Neptune are classified as "ice giants". They have a similar atmosphere to "gas giants" Saturn and jupiter and Neptunes atmosphere is primarily composed out of hidrogen and helyum. So the correct answer is a.</span>
It would probably be <span>Premature Ventricular Contractions.

So, physical properties are what we can detect with our basic 5 senses or measuring tools, and the things that, when changed, dont actually change the chemical properties (like atoms and molecules). Lets take wood for an example: its brown, its solid, it can be big or small, it has a taste and smell, its boiling, freezing or melting point...
Chemical properties, on the other hand, are the things we can change with, for example, experiments and tools. Does it burn? Can it rust/oxidize? How does it react with other chemicals? Is it radioactive, or toxic? All of these are chemical properties you can probably answer.
Explanation:
Impulse = change in momentum
FΔt = Δp
(53 N) (15 s) = Δp
Δp = 795 kg m/s
For constant mass:
Δp = m Δv
795 kg m/s = (12 kg) Δv
Δv = 66.25 m/s
Rounding to two significant figures, Δp = 800 kg m/s and Δv = 66 m/s.
