Current, I got it right on my quiz
<span>It's another energy balance equation, though: energy to start with is the same as energy that you end with. Suppose that we start a distance r0 from the Earth and end a distance r1 from the Moon, then the energy balance gives:
1 v02 - G M / r0 - G m / (D - r0) = 1 v12 - G M / (D - r1) - G m / r1
...where m is the moon's mass.
One simple limit takes D ? ? and 1 v02 ? G M / r0 (the escape velocity equation), to yield:
1 v12 ? G M / r1
v1 ? ?( 2 G M / r1 ) = 2377 m/s.</span>
As the mass of jupiter is more than the mass of earth it has a greater graviationsl force in it........as we know that our weight depends on mass of object and thr gravitational force on it......if the gravitational force is increased the object's weight will definitely increase......
Due to more mass of jupiter than earth it means that there are more forces acting on every single point where mass acts......if these points are more the gravitational force will also increase.......
HOOE IT HELPED !!!!
The answer is 259.2 .... divide 360 by 100 and then that answer times 72.
Answer:
, negative charge
Explanation:
The magnitude of the electrostatic force between the two red blood cells is given by
where
k is the Coulomb's constant
q1 and q2 are the charges of the two cells
r is their separation
In this problem we know that
r = 1.46 m
Solving for q2, we find
And the force between the two cells is attractive, so since the first cell has positive charge, this second cell must have negative charge.
