The arrows below represent the velocities of two vehicles. Bus
Which claim explains why the velocity of each vehicle is a vector quantity?
It can change over time.
It has direction and size.
It is a measurable quantity.
It uses a measure of speed.

8

explanation:

each principal energy level above the first contains one s orbital and three p orbitals. a set of three p orbitals, called the p sublevel, can hold a maximum of six electrons. therefore, the second level can contain a maximum of eight electrons - that is, two in the s orbital and 6 in the three p orbitals.

mark brainliest and have a great day!

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).

the answer is 75.0%.
