The gravitational force exerted by the planet Earth on a unit mass at a distance r from the center of the planet is F(r) = GMr R

bagirrra123 [75]

Answer:

Yes the function is continuous.

Step-by-step explanation:

Given

$F(r)=\frac{GMr}{R^{3}}(r< R)$ and $F(r)=\frac{GM}{r^{2}}(r\geq R)$

For a function to be continuous we should have

$\lim_{r\rightarrow R^{-}}F(r)=\lim_{r\rightarrow R^{+}}F(r)$

Thus

$\lim_{r\rightarrow R^{-}}F(r)=\frac{GMR}{R^{3}}=\frac{GM}{R^{2}}$

Similarly we have

$\lim_{r\rightarrow R^{+}}F(r)=\frac{GM}{R^{2}}$

thus we can see that

$\lim_{r\rightarrow R^{-}}F(r)=\lim_{r\rightarrow R^{+}}F(r)$

Hence the function is continuous.

Y=25000(1-0.63)^2<br> Find the decay rate.

Anestetic [448]

If I'm not mistaken.. the half-life should be 40,750 years.. so

y = 40,750

I got this by multiplying 25,000 by 1.63 and then if you divide by 2.. you get

20,375.. so one of those should be correct
