Two boats start together and race across a 60-km-wide lake and back. boat a goes across at 60 km/h and returns at 60 km/h. boat b goes across at 30 km/h, and its crew, realizing how far behind it is getting, returns at 90 km/h. turnaround times are negligible, and the boat that completes the round trip first wins. (a) which boat wins and by how much? (or is it a tie? ) (b) what is the average velocity of the winning boat?

b) returns freshwater to the earth.

c) returns freshwater to the earth.c) occurs after condensation.

d) returns freshwater to the earth.c) occurs after condensation.d) roughly equal to the amount of evaporation.

happy to

pls mark as brainliest.

unlike poles attract

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.
