A satellite is in a circular Earth orbit of radius r. The area A enclosed by the orbit depends on r2 because A = πr2. Determine
Salsk061 [2.6K]

Answer:

a. T=r^{3/2}

b. K=\frac{1}{r}

c. v=\frac{1}{\sqrt{r}}

d. v=\sqrt{r}

Explanation:

To make analysis about the satellite circular earth the depends or r and A

T^2=\frac{4\pi}{GM}*r^3

K=\frac{GM*m}{2*r}

a.

T^2=r^3

T=r^{3/2}

b.

K=\frac{GM*m}{2}*\frac{1}{r}

K=\frac{1}{r}

c.

K=\frac{1}{2}*m*v^2

v^2=\frac{2*K}{m}=\frac{2*Gm*m}{2*m*r}

v=\frac{1}{\sqrt{r}}

d.

v=\sqrt{2*GMr}

v=\sqrt{r}

Delvig [45]

Scientists conduct multiple trial experiments because one test might not be as reliable as multiple trials. Another reason they conduct multiple trials is because the scientific method says to conduct multiple experimental tests.
