Explanation:

Prime meridian is an imaginary line which bisect earth in western and eastern part.

Polaris is a north star at 50 degree above the horizon, which means 50 degree latitude.

if we observe Polaris at 50 degree of altitude it means we are at the latitude of 50 degree north.

That's why we know that our boat is at North latitude and longitude.

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
