A car moved 50 km West and 80 km East in 2 hours. What is its average velocity
in m/s and km/h?

can be answered using momentum.

momentum = p

p1= mass1 * velocity1

p1 = p2

therefore

p1 = 6kg * 4m/s

p1 = 24kgm/s

p2=m2 * v2

24 kgm/s = 7kg * v2

v2 = 24 kgm/s / 7kg

v2= 3.42 m/s

c because the news are a source of information of things that happen on the daily and shows evidence about that particular topic

force tends to be low and long diustance masses are high

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).
