The two factors that affect the period of a pendulum are the length of the string and the distance in which the pendulum falls.
Hope this helps! I would greatly appreciate a brainliest! :)
<span>The mass of an electron is not significant to the overall mass of the atom. (B)
It takes roughly 1,850 electrons to equal the mass of ONE proton or neutron,
but the most complex atom has only around 100 of them.</span>
B. transition metals for sure
Same speed, because mass is neglected. The things that affect the speed are the distance and speed of the rock.
