Change units:

1 mile = 1609.34 m = 1609.34 * 10^6 micro m = 1.60934 * 10^9 m

1 hour = 3600 s = 3600 * 10^9 nano seconds = 3.6*10^12 nano sec

3 miles / hour = 3 * 1.60934 * 10^9 / (3.6*10^12) = 0.0013411 micro m/nano second = 1.3411*10^(-3) um / ns

Do metals donate or accept electrons? what do they become after they donate/accept electrons?
valentinak56 [21]
Metal usually donates electrons. The concept behind this phenomenon is stability. The elements with the most stable electronic configuration are the noble gases in Group 5A. As a result, the other elements donate or accept electrons so that they would be like the noble gases. Since metals are past their nearest noble gas element, they have to shed their electrons. When they do, they become cations which are positively charged ions.

Can someone Summarize how the suns gravity affects the planets please.
egoroff_w [7]

The sun's gravity pulls the planet toward the sun, which changes the straight line of direction into a curve. This keeps the planet moving in an orbit around the sun. Because of the sun's gravitational pull, all the planets in our solar system orbit around it.
