because growing process had stoped after 4-5 year

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

higher potential

explanation:

because it is in a high speed so it must move into a of high potential
