Tectonic plates are large segments of the earth's crust that move slowly. suppose that one such plate has an average speed of 3.5 cm/year. (a) what distance does it move in 1 s at this speed?

Distance= 3.5/31536000 cm = 1.11 × 10^(-7) cm

Explanation:

Given ;

Average speed = 3.5cm/year

Time= 1 s

Distance = speed × time

Number of seconds in a year = 31536000 sec/year

Distance = 3.5 cm/year × 1/31536000sec/year × 1 s

Distance= 3.5/31536000 cm = 1.11 × 10^(-7) cm

an ion is a charged atom or molecule. it is charged because the number of electrons do not equal the number of protons in the atom or molecule. an atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom.
