Answer:

g = 8.61 m/s²

Explanation:

distance of the International Space Station form earth is 200 Km

mass of the object = 1 Kg

acceleration due to gravity on earth = 9.8 m/s²

mass of earth = 5.972 x 10²⁴ Kg

acceleration due to gravity = ?

r = 6400 + 200 = 6800 Km = 6.8 x 10⁶ n

using formula

 g = \dfrac{GM}{r^2}

 g = \dfrac{6.67\times 10^{-11}\times 5.972\times 10^24}{(6.8\times 10^6)^2}

        g = 8.61 m/s²

Nina [5.8K]

Answer:

1 × 10⁶ N/C

Explanation:

The magnitude of the electric field between the membrane = surface density / permittivity of free space = 10 ⁻⁵C/ m² / (8.85 × 10⁻¹²N⁻¹m⁻²C²) = 1.13 × 10⁶ N/C approx 1 × 10⁶ N/C

Nataliya [291]

Answer:

v=-30 m/s

Explanation:

Using the equation:

v=u+at

v=?

u means initial velocity=0

a=-10 since it is going down we make the acceleration due to gravity negative

t=3

v=0+(-10)(3)

v=-30 m/s

It decreases The factor of two.

Step by step explanation

If she spin at a angular speed of 2w, and an initial speed of fi, when she slows down she is only has a angular speed of W, meaning that decreased 2

PS the anwser above me is wrong because in the question it said she decree so I couldn’t have stayed the same.

Hope this helps!
