Answer:
<em>The power output of the engine is 1,000 Watt</em>
Explanation:
<u>Mechanical Power
</u>
Power is the amount of energy transferred or converted per unit of time. In the SI, the unit of power is the watt, equal to one joule per second.
The power can be calculated as:
Where W is the work and t is the time.
The engine does a work of W=60,000 J during t=60 s. Calculate the power:
P = 1,000 Watt
The power output of the engine is 1,000 Watt
Answer:
C. Surface area
Explanation:
The rate of chemical reaction depends on various factors such as:
- concentration and pressure
- nature of reactants
- temperature
- surface area
- presence of catalyst, etc.
Effect of surface area of reactants: the rate of a chemical reaction can be increased by increasing the the area of contact of the reacting substances. This is especially important when one or more of the reactants are solids., because only the particles of the solid that are exposed are able to take part in the reaction at each instant of time. Therefore, the greater the surface area of the solid reactant particles the faster the reaction.
The surface area of solid reactants can be increased by grinding or pelletizing, thus allowing for a greater contact between the reacting particles,
The instance in which one of the solid reactants was treated in a coffee grinder before adding to the reaction container is one way of increasing the surface area of a reactant.

Explanation:
Answer : The main benefits of Nuclear Energy are because it is more efficient than burning most fossil fuels than the amount of energy that is released from the uranium per gram is much more than fuels such as oil and coal. This is approximately eight thousand times more efficient.
