Average speed is the answer
Start with 2,000 grams.
After 1 half-life, 1,000 grams are left.
After another half-life, 500 are left.
After another half-life, 250 are left.
After another half-life, 125 are left.
That was FOUR half-lifes.
X = 4 .
<span>Answer:
So at joints C and D do I let there be a Cx, Cy and Dx, Dy respectively or do I just keep it as Fwd and Fwc? Either way I can't seem to solve it. â‘Fx=0=WD-4293cos19.74 ÎŁFy=0=Fwc Sin19.74 - 1450 Fwc= 4203 lb WD = 4041 lb Then at joint C â‘Fx=0=CDsin30 - CAsin30 - 4041 â‘Fy=0=1450-CDcos30-CAcos30 CD = 4878 CA = -3204 Incorrect.

The ratio is
Explanation:
From the question we are told that
The period of the satellite is
Generally the period of earth around the sun is
Generally from Kepler's third law , which is mathematically represented as
Here is the radius of the orbit which the satellite rotate around the sun
