Answer:
12500 J = 12.5 kJ
Explanation:
Kinetic energy is the energy possessed by a moving object solely due to its motion.
You can get the K.E. of an object using the equation,
K.E. = (1/2)mv²
So you get, for ball
K.E. = (1/2)×1000×5² = 12500 J = 12.5 kJ
Answer:
The answer is: volcano.
Explanation:
The mid-ocean ridges are underwater elevations located in the middle part of the Earth's oceans.
The chain has a very rugged relief, with wide slopes and ridges often marked by a deep longitudinal recess, called the sinking or rift valley, along which numerous surface earthquakes and volcanic eruptions occur that pour basalt lavas.
The answer is: volcano.
Answer:
The core muscles stabilize and protect the spine. They help control all movements and make it possible for us humans to walk and stand up right. The core helps us transfer energy, shift our body weight and reach/move in different directions. It is important to have a strong set of core muscles because it makes everyday activities easier.

Answer: 5.9 m/s
Explanation:
This problem can be solved by the Conservation of Momentum principle, which establishes that the initial momentum must be equal to the final momentum :
(1)
Where:
(2)
(3)
is the mass of the skater
is the mass of the ball
is the initial velocity of the skater and the ball
is the final velocity of the ball
is the final velocity of the skater
Substituting (2) and (3) in (1):
(4)
Isolating :
(5)
(6)
Finally:
