Answer:
The average distance is 999.936 light years.
Solution:
As per the question:
Ours is the Milky Way Galaxy with the diameter:
D = 1,00,000 ly
Radius, R =
Now,
A =
The area to each civilization, A' is:
A' =
The radius of each area of civilization, r:
Thus the average separation distance between civilizations is given as:
2r =
A. something that happens when a force is applied to an object and its moved
(however all 3 answers are arguebly correct)
Explanation:
We use Hooke's Law, which states that,
F=kx
F- is the force in newtons
k- is the spring constant
x- is the extension of the spring in meters
Solving for k we get k=F/x
k= 10N/0.50m
=100 N/m
<span>We know that the moviment of acceleration due the gravity accomplish the following rules:
H = Vi * T + 1/2 * g * T^2 and V = Vi + g* T
where: H is height, Vi is initial speed, T is time and g is gravity acceleration
Then, as we drop off the stone, means initial speed is zero, so we can calculate first the time to hit the ground
V = Vi + g * T => 112 = 0 + 32 * T => T = 3.5 seconds
Within that time the height dropped by the stone will be:
H = Vi * T + 1/2 * g * T^2 = 0 * 3.5 + 1/2 * 32 * 3.5^2 = 196 ft
So we conclude that the height of the cliff is 196 feet.</span>
