(a) the principle of aerodynamic convergence
(b) the centripetal force
(c) Conservation of angular momentum
(d) Conservation of kinetic energy
(e) None of these
Conservation of angular momentum
Answer: Option C.
<u>Explanation:</u>
The law of conservation of angular momentum expresses that when no outer torque follows up on an article, no difference in precise force will happen.
The law of conservation of angular momentum expresses that the angular energy of a body that is the result of its snapshot of latency about the hub of revolution and its rakish speed about a similar pivot, can't change except if an outside torque follows up on the framework.
Yes because there is more temperature to cover in terms of hot water turning into cold and then solid water, and therefore hot water cools down faster, whereas cold water will take more time to become solid.
There may be an improper voltage in the device.
<u>Explanation</u>:
- Given the device has unknown circuitry and the voltage across the device crosses the voltage across the resistor at 500 Hz. In this device, the current flow is not correct. It is improper.
- The elements in the device are ammeter, capacitor, inductor, voltmeter, and battery. The components in the device may not be connected properly. This is due to the improper flow of current and condition of the voltmeter.
- So these are the type of elements in the device.
