Arunner increases her speed from 3.1 m/s to 3.5 m/s during the last 15 seconds of her run what was her acceleration during her big push to the finish?

A=v-u/15
a=3.5-3.1/15
a=0.4/15
a=0.02666666
.:a =0.03m/s2 (2 represents a square root)

There is one s orbital, and there are three p orbitals, five d orbitals, and seven f orbitals. thus, the answer is b. do not confuse the number of orbitals in a subshell with the number of electrons the subshell can hold. each orbital can hold two electrons, so the capacity of an nf subshell is 14 electrons.
