Answer:
Kinetic energy is the energy obtained from movement while potential energy is the energy in something when it is at a height or has been manipulated in some way; it has work done to it.
Explanation:
Kinetic energy is, like I said, energy gained through movement or action. When an object stops moving, it converts into a different type of energy. Energy cannot be destroyed or created. An object with potential energy has a reference. A reference determines how high it is. The higher and heavier an object is, the more potential energy it has.
Hope this helps!
18.5164213 if you divide them both you get that number so the volceity is the number shown above.
We can reasonably improve a machines ability to do work by reducing the friction between the moving parts of machine.
Answer:
s = 1800 m = 1.8 km
Explanation:
The distance, the speed, and the time of reach of the sound are related by the following formula:
where,
s = distance
v = speed
t = time
FOR WATER:
---------------------- eq (1)
where,
s = distance between ship and diver = ?
= speed of sound in water = 1440 m/s
t = time taken by sound in water
FOR AIR:
---------------------- eq (2)
where,
s = distance between ship and diver = ?
= speed of sound in water = 344 m/s
t + 4 s = time taken by sound in water
Comparing eq (1) and eq (2),because distance remains constant:
t = 1.25 s
Now using this value in eq (1):
<u>s = 1800 m = 1.8 km</u>
Answer:
Explanation:
Electrical energy = potential x charge
potential = 12V ,
Charge = 95 amp-hours
= 95 x 60 x 60 coulomb
= 342000 coulomb
Electrical energy stored in battery = 342000 x 12
= 4104000 J
= 4.1 x 10⁶ J .
