Answer:-50.005 kJ
Explanation:
Given
mass of system =10 kg
work done=0.147 kJ/kg
Change in elevation
initial velocity
Final Velocity
Specific internal Energy
from first Law of thermodynamics
where KE= kinetic energy
PE=potential energy
U=internal Energy
Q=1.47+3.375-4.850-50
Q=-50.005 kJ
In energy production, possible sources are fossil fuels like coal, petroleum and natural gas. Other sources are renewable like hydro, solar and wind. Radioactive elements are also possible sources for nuclear energy. However, energy will always dissipate. Industries could never get 100% of the energy from their sources. In ideal cases like the Carnot engine, we can only get 60% of the energy. That is ideal. In actual, we get even lesser than this for about 40%.
When the efficiency is 60%, the used energy is 60%, while the wasted energy is 40%. Therefore, the wasted energy is
1000 BTU (0.40) - 400 BTU
The waste energy in the form of electricity is 400 BTU.
Answer:
Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion. Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position.
