Answer:

13 minutes

Step-by-step explanation:

∵ Joe runs 8 miles in the time = 1 hour or 60 minutes

∴ Joe runs 1 mile in the time = \frac{60}{8} minutes

∴ Joe runs 13 miles in the time = \frac{60\times 13}{8} minutes

                                                   = 97.5 minutes

∵ Marjorie runs 8 miles in the time = 52 minutes

∴ Marjorie runs 1 miles in the time = \frac{52}{8}

∴ Marjorie runs 8 miles in the time = \frac{52\times 13}{8}

                                                         = 84.5 minutes

Therefore, times taken less by Marjorie to complete the marathon = 97.5 - 84.5 = 13 minutes.

69) Half-way to the center of a planet of uniform density, your weight compared to that at the surface would be :
mel-nik [20]

Answer:

One- half

Step-by-step explanation:

Since the density is uniform  

Mass of the sphere = [(4/3) π r^3] d

where d is the uniform density.

Mass of the sphere = [(4/3) π d] r^3 = k r^3

where k = [(4/3) π d] is a constant  

Weight = mg = G m M / r^2 = G m [k r^3] /r^2 = G m k r

Using Gauss’ law for gravitation,

Half way to the center of a planet the weight is only due to the inner sphere and the outer sphere does not contribute to his weight,  

Inside his weight is mg’ = (G m k  r) /2   = mg/2  

Answer is one-half.
