I think first one
Explanation:
Because his first law of motion was every object will remain at rest or uniform motion in a straight line
Answer:
56.25 m
Explanation:
Cinematics describes the variables involved in movement without dealing with its causes. There are four main concepts in cinematics: Velocity (or its scalar equivalent, the speed), acceleration, time and displacement (or its scalar equivalent, distance).
We know the bobsled starts at 32m/s and ends at 22m/s with acceleration . The acceleration is negative because the bobsled is breaking of losing speed
The formula relating these three variables is
Solving for x
Answer:
97% will sink below the water
Explanation:
Waters density is 1 g/cm3
If an object's density is greater than 1g/cm3, it will sink. If it's less then it would float. 1-0.97 = 0.03. Only 3% of the ice would show while 97 will be under.
Answer:
the molecules get close together and the water expands
