Answer:
8091.36
Explanation:
Calculation for the rotational kinetic energy
First step is to calculate the inertia of the wheel
Wheel Inertia=1/2*12(0.28^2+0.33^2)
Wheel Inertia=1/2*2.2476
Wheel Inertia=1.1238
Now let calculate the rotational kinetic energy
Rotational kinetic energy=1/2*1.1238*120^2
Rotational kinetic energy=1/2*1.1238*14,400
Rotational kinetic energy=8091.36
Therefore the rotational kinetic energy will be 8091.36
<span>Marx believed that the root cause of all misery in society was class conflict—the exploitation of the working classes by those who were wealthy and owned the means of production.
</span><span>Weber believed that religion was the central force in society. He used cross-cultural and historical materials to trace the causes of social change.</span>
Answer:
Power is defined as Work / Time
P1 = P2 = W1 / T1 = W2 / T2 W1 and W2 are not necessarily the same Power expended depends on both work input over a unit of time
Answer:
9 ft*lb
Explanation:
super simple but you just have to understand that the integral is going with the curve
work = integral a to b of f(x)dx = integral 0 to 9 of 10/(1+x)^2dx = 9ft*lb
What is the value of the voltage? There must be one somewhere.
This might be too simple minded, but I'll give it a voltage of 10 Volts.
R = voltage / Current
R = 10 / 0.5
R = 20 volts.
Perhaps you could post a diagram if this is a Kirchhoff Law Question.
