(3) 10.1 second
Using equation of motion 500 = (0.5)(9.81)t^2. Rearranging, t = sqrt(1000/9.81) = 10.1s
Answer:
Knowing we only have one load applied in just one direction we have to use the Hooke's law for one dimension
ex = бx/E
бx = Fx/A = Fx/π
Using both equation and solving for the modulus of elasticity E
E = бx/ex = Fx / πex
E = 
Apply the Hooke's law for either y or z direction (circle will change in every direction) we can find the change in radius
ey = 
(бy - v (бx + бz)) = 
бx
= 
= 
Finally
ey = Δr / r
Δr = ey * r = 10 * 
Δd = 2Δr =

Answer:
100years later
Explanation:
Because the lights will arrive at world after 100 years later.
Explanation:
In physics, a force is any interaction that, when unopposed, will change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity.
Formula
Newton's Second Law
F = m * a
F = force
m = mass of an object
a = acceleration
