A watershed supplies water to a river system.
Answer:
because darkness is the absence of light, so that means darkness was there before the light came! :)
Explanation:
Answer:
The answer is A.) Mass is a measure of the amount of matter in an object, while weight is a measure of the force of gravity on the object.
Explanation:
Your weight would change if you went to the moon because the gravitational pull is different but your mass would stay the same because the amount of matter in you wouldnt change.
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
