Answer:
14.16 W
Explanation:
We have given impedance Z=91.5 ohm
Voltage across the resistor = 36 V
We have to find the power delivered by the source
We know that according to telegens theorem , the absorbed = power delivered
So the voltage across the resistor = 36 V
Current in the RLC circuit 
this current will be same in the whole circuit as it is a series RLC circuit
Now the power absorbed by the resistor 
As the power absorbed = power delivered
So power delivered by the source =14.16 W
Answer:
The dart with the small mass will travel the farthest distance.
Explanation:
Acceleration is proportional to force times mass, and inertia is proportional to mass. Inertia is the reluctance of a moving body to stop, and a stationary body to start moving (inertia increses with mass). Assuming they both have the same aerodynamic design, and that they are both launched with the same force applied for the same time duration, the dart with less small mass will accelerate faster than the big mass dart. From this we can see that the small dart will have covered a longer distance before the effect of the force stops, when compared to the more massive dart.
Answer:
4 Joules (if you mean 2000 grams)
4000 Joules (if you mean 2000 kilograms)

Explanation:
By Hooke's Law,
F=kx
The only force acting here is weight, and x is the extension of the string (you need to convert this to mm) so
mg=kx
(0.15)(9.81)=k ((420-300)x10^-3)
Then just solve this equation.
A. You measure power on watts.
B. Non-renewable
C.renewable
D. Joules
E. Fossil fuels
