Answer:
A factor of 2*4 = 8
Explanation:
F_g = (G*m1*m2)/r^2
where m1 and m2 are the two masses, G is Newton's gravitational constant, and r is the distance between the center of mass of the two objects.
So, if you double m1 and quadruple m2:
m1' = 2*m1
m2' = 4*m2
Then F_g' = (G*m1'*m2')/r^2 = (G*2*m1*4*m2)/r^2 = 8*(G*m1*m2)/r^2 = 8*F_g
The answer is marine west coast, humid subtropical and Mediterranean. <span />
The solution for this problem is:
500 revolution per
minute = 8.33rev /s = 2π*8.33 rad /s = 52.36 rad /s
Angular velocity ω = 2π N
Angular acceleration α= (ω2 - ω1) /t
ω2 = 0
α = - ω1/t = -2π N /t
N = 500 rpm = 8.33 r p s.
α = -2π 8.33 /2.6 =- 20 rad/s^2
Geocentric means earth centered
So answer is C - the earth in no longer believed to be the center of the solar system
1. Single dental x-rays: 
The energy of the photon is
Using the conversion factor
we can convert it into Joules:
The relationship between photon energy and wavelength is
where
is the Planck constant
is the speed of light
E is the energy
Substituting into the formula, we find
2. Microtomography: 
The energy of these photons is 2.5 times greater, so
And by applying the same formula used at point 1, we find the corresponding wavelength:
