In a crash test, a 2,500 kg car hits a concrete barrier at 1.3 m/s2
Calculate the amount of force at which the car strikes the barrier.
The car strikes the barrier with a force of

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!

it is b that is the answer.

5.6⋅10−^19  j

do you need the explaination?

alchemy hadn't scientific methods of study, appeal to mysticism and fantasy, the knowledge of chemistry and physics were modest at that time.

alchemy was - but as new rules were discovered it either changed into chemistry or it became "unscientific".
