Answer:
1752.14 tonnes per year.
Explanation:
To solve this exercise it is necessary to apply the concepts related to power consumption and power production.
By conservation of energy we know that:
Where,
Production of Power
Consumption of power
Where the production of power would be,
Where,
m = Total mass required
Energy per Kilogram
Efficiency
The problem gives us the aforementioned values under a production efficiency of 45%, that is,
Replacing the values we have,
Solving for m,
We have the mass in kilograms and the time in seconds, we need to transform this to tons per year, then,
tonnes per year.
Answer:
The toy car
Explanation:
the real car is parked so yeah but maybe in some way technically the real car has more "momentum"
Yes? I think a tutor would help with this!!!!
Answer:
His first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. In other words its inertia.
Explanation:
Answer:
Explanation:
The work (W) done by the gas can be calculated using the following equation:
<u>Where:</u>
p: is the pressure
[tex}V_{f}[/tex]: is the final volume
[tex}V_{i}[/tex]: is the initial volume
In the first process, the work done by the gas is:
Since the volume remains constant, the total work done by the gas is equal to zero.
In the second process, the work done by the gas is:
Now, the total work done by the gas during both processes is:
Therefore, the total work done by the gas during both processes is - 24 kJ.
I hope it helps you!
