Answer:
6.5 m above the floor and 5 m above Christine's hand when it reaches the maximum height.
Explanation:
Let g = 10 m/s2 be the gravitational deceleration that affects the ball vertical motion so it comes to the maximum height at 0 speed. We can use the following equation of motion to find out the distance traveled by the ball from where it's thrown:
where v = 0 m/s is the final velocity of the ball when it reaches maximum level, 
= 10m/s is the initial velocity of the ball when it starts, g = -10 m/s2 is the deceleration, and 
is the distance traveled, which we care looking for:
So the ball is 5 m above Christine' hands when it reaches maximum height, and since the hand is 1.5 m above the floor, the ball is 5 + 1.5 = 6.5 m above the floor when it reaches maximum height.
Answer:
A small force is applied over a long time interval can produce a large change in the object's momentum

24N
Explanation:
Calculation for what his weight would be
Let his WEIGHT on the surface of earth be 600 and Let the RADIUS be 25 which is (5^²) because we were told that the radius is FIVE TIMES larger than earths
Now let calculate his weight using this formula
Weight=Weight on Earth/Radius
Let plug in the formula
Weight=600N/5^²
Weight=600N/25
Weight=24N
Therefore his weight would be 24N
Answer:
The atomic number is the number of protons in an atom's nucleus.
The atomic number is important, because it determines which element an atom is.
