The following scenarios that accurately describes a
condition in which resonance can occur is vibrating tuning fork is struck and
begins to vibrate as the object used to strike it is placed away from the
tuning fork. The answer is letter B.
(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.
Voltage = N * Δ(BA)/Δt
<span>BA = 0.57*0.16*0.22 = 2.0064e-2 </span>
<span>N = 505 </span>
<span>115/505 = Δ(BA)/Δt = 23/101 </span>
<span>When the top of the coil rotates to the bottom (1/2 half cycle) BA changes from max to min and when the bottom rotates back to the top BA changes from min to max. So Δ(BA) is twice per cycle </span>
<span>So 2*101Δ(BA)=23Δt and Δt = 1/f </span>
<span>202*2.0064e-2/23 =Δt = 1/f => f =5.675Hz</span>
Resistance is a measure of the opposition to current flow in an electrical circuit. Resistance is measured in ohms, symbolized by the Greek letter omega (Ω). Ohms are named after Georg Simon Ohm (1784-1854), a German physicist who studied the relationship between voltage, current and resistance.
