Answer:
c
Explanation:
because the other would not make sense
Artificial gravity is created by rotating the cylinder
So here we can say that the acceleration is due to centripetal acceleration
So here we know that the formula of centripetal acceleration is given by
so here we know that
now we will plug in all values
So above is the radius of the cylinder
Now to find the diameter
so its diameter is 194.8 m
The correct answer is B: a set of dimensions
The answer is B because if you use process of elimination, you find that A is invalid because Venus is the second planet. C is out because Mars is the 4th planet. D is out because we are nowhere near the Andromeda Galaxy. We are millions of light years away.
Answer:
a. The horizontal component of the velocity is constant so vxt = d where vx = v0 cosθ = 16m/s t = d/v = 2s
b. The height of the ball during its flight is given by y = v0yt + ½ gt2 where v0y = v0sinθ = 12m/s and g = –9.8m/s2 which gives at t = 2s, y = 4.4m. The fence is 2.5m high so the ball passes above the fence by 4.4m – 2.5m = 1.9m
