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>
Answer: 4 x 106
That’s how you write forty million in scientific notation.
D. Velocity because it describes a speed and direction
Answer:
Speed is the rate at which an object's position changes, measured in meters per second. The equation for speed is simple: distance divided by time
Explanation:
