g A very early, simple satellite consisted of an inflated spherical aluminum balloon 38 m in diameter and of mass 22 kg. Suppose a meteor having a mass of 21 kg passes within 8.0 m of the surface of the satellite. What is the magnitude of the gravitational force on the meteor from the satellite at the closest approach?

6.37*10^-13 N

Explanation:

Given that

We r = 38/2 = 14 m

m1 = 22kg

m2 = 21 kg

so we can say that distance between center of the satellite and meteor,

d = r + h

= 14 + 8

= 22m

So the gravitational force on the meteor, is

F = G x m1 x m2/d²

= 6.67*10^-11 x 21 *22/22²

= 6.37*10^-13 N

the aurora is formed when charged particles emitted from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere. these collisions result in countless little bursts of light, called photons, which make up the aurora.

auroras are generated by charged solar particles hitting molecules in earth's atmosphere. this usually happens in high latitudes, because our planet’s magnetic field tends to funnel these particles toward the poles. that’s why it can be experienced in northern ohio.
