Pluto’s diameter is approximately 2370 km, and the diameter of its satellite Charon is 1250 km. Although the distance varies, th

MissTica

Answer:

$r_{cm} = 2520.5 km$

Explanation:

As we know that mass is the product of volume and density

so we will have

$M = \rho V$

here we have

$M = \rho(\frac{4}{3}\pi r^3)$

so we will have

$\frac{M_p}{M_c} = (\frac{r_p}{r_c})^3$

so we will have

$\frac{M_p}{M_c} = (\frac{2370}{1250})^3$

$M_p = 6.81 M_c$

now let the position of Pluto is at origin so we have

$r_{cm} = \frac{M_p (0) + M_c(19700)}{M_p + M_c}$

$r_{cm} = \frac{19700}{\frac{M_p}{M_c} + 1}$

$r_{cm} = \frac{19700}{6.81 + 1}$

$r_{cm} = 2520.5 km$

Complete Question

The complete question is shown on the first uploaded image

Answer:

The value of $X = 1000 \ N$ and $Y = 1400 \ N$

Explanation:

Considering the diagram,

Taking moment about the pivot , we have

$X * 1 = 400 * 2.5$

=> $X = 1000 \ N$

Generally given that the bar is at equilibrium then the upward forces is equal to the down ward force

$Y = X + 400$

=> $Y = 1000 + 400$

=> $Y = 1400 \ N$
