Answer:
12.245m3
Explanation:
The electric energy is created by The potential energy substended by the specific volume of water in dam.
Electric energy is calculated as
E= Q× V
E is Energy, Q is charge and V is Voltage
Note that this energy has been given and is 60Joules
From conservation of energy it means;
M× g×h = 60
Where M is the mass of water.
g is acceleration of free fall due to gravity which is 9.8m/S2
h is the height of water flow.
From change of subject of formula for M; we have:
M = 60/ g × h
= 60/ 9.8 × 0.5
= 12.245kg
Now how much water required means the volume of water;
Note density = mass/volume
Therefore volume = mass/density
=12.245/1= 12.245m3
Note the density of water is 1kg/m3
RADIATION
There are three types of heat transfer or heat propagation; conduction, convection and radiation. Heat transfer is the process by which heat projects externally however, depending on the temperature and pressure. Also called the movement of heat from a low temperatured state which increases as heat progresses.
Conduction is the heat transfer by contact, immediate contact.
Convection is the transfer of heat through air and water.
<span>Radiation is the transfer of heat regardless of the presence of atoms or particles.<span>

Answer:
Bowling Ball
Explanation:
The potential energy depends on the factors: mass of the object and distance between the two objects. In this case the distance is between the ground and the balls. Here, the bowling ball is heaviest and its center of mass is farthest in comparison to other two balls. Thus, it has the greatest potential energy.
