Answer:A) noble gases
Explanation: key word gas. if you fart it smells and other gases harm.
It implies the following thing. If you draw a vector connecting the Sun and a planet this vector will be covering equal areas in equal time spans. Say, each second, this vector covers N square meters, each 2 seconds - 2N square meters and so on
Answer:
a1 = (V2 - V1) / 1 s = 3.75 m/s^2
a2 = (V2 - V1) / (t2 - t1) = (7.5 - 3.75) / 1 s = 3.75 m/s^2
a3 = (V2 - V1) / (t2 - t1) = (7.5 - 3.75) / 1 s = 3.75 m/s^2
A) a = (a1 + a2 + a3) / 3 = 3.75 m/s^2
v = a (t2 - t1)
B) after 1 sec v = 3.75 m / sec^2 * 1 sec = 3.75 m/s
after 2 sec v = v0 + a t = 3.75 m/s + 3.75 m/s^2 * 1 s = 7.5 m/s
C) The velocity increases proportionaly to the time
D) One factor depends on the variation of the acceleration due to gravity because of different positions of measurement (on earth)
A much larger factor is due to air resisance of the air on the falling object
One should never anchor in a narrow channel, until unless required very importantly. One should stay to the starboard side, and use a prolonged blast. The announcement must be done to alarm the nearby vessels, about your approach. The vessel should be kept at the outer limit of the starboard side.
