A 38kg child is at the top of a slide that is 2.1m tall. If there is no friction, how fast will they be moving when they reach the bottom of the slide?

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

im guessing the west of station b

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg
