Answer: The answer is B
Explanation:
Work can be defined as the energy that is required to apply a force to an object in order to move it from one point to another. In physics, work = force x distance travelled. On the other hand, Power is the work done per time. In other words, it the rate at which work is done and is determined by using the formula, Power = Work/time. In these relationships, it can be seen that power is directly proportional to the amount of work done, hence as power increases, more work is done.
779,247 J is the amount of heat released.
<u>Explanation:</u>
The equation that gives the amount of heat supplied is

Where,
E or Q – amount of heat supplied
m- mass
- specific heat capacity of Aluminium
– temperature variation caused by heat change
The amount of heat energies that causes the temperature to vary
or 1 K per kg of the material is known as specific heat capacity (c)
Here, Given data:
– 0.900 J/g.K
To convert gram into kilogram, multiply and divide by
, we get
Specific heat capacity of aluminum = 900 J/kg. K
m – 5.89 kg

By substituting the known values in the above equation, we get
