It is 6 g/cm3 because density cannot be negative, and it is not speed in which the unit would be m/s.
Work = Force * distance
Force = 70 N
Work = 3500 J
3500 = 70d
d = 3500/70 = 50 m
Pressing two objects together with more force Increase friction
Answer-A
The water cycle shows how water moves around earth.
Ex: Runoffs,precipitation, condensation, evaporation.
