Answer:
Explanat Enthalpy of Vaporizationion:
I believe the answer you are looking for is 1.4 N.
0.145*9.8=1.42
So you round 1.42 to 1.4
Hope this helps!
Answer:
Tides on our planet are caused by the gravitational pull of the Moon and Sun. Earth's oceans "bulge out" because the Moon's gravity pulls a little harder on one side of our planet (the side closer to the Moon) than it does on the other. The Sun's gravity raises tides, too, but lunar tides are twice as big.
Answer: An object's velocity (a vector) does not change if and only if the net force acting on the object is zero. In other words, if there is no net force on an object, its speed and direction of motion do not change (including if it is at rest).
