think you messed up the symbol for resistor as resistors are measured in ohms where the symbol used for ohms is Greek omega
solving for average power in secondary coil:
average power =(current rms)^2*resistance⇒with a little algebra:
current rms=(√average power/resistance)
current rms=√160W/10Ω
current rms=4amps.
average power is also equal to current rms*voltage rms
with some algebra we can solve for voltage in the secondary wire:
voltage rms= average power/ current rms
voltage rms= 160W/4A
voltage rms=40Volts
now that we have voltage in the soecondary we can solve for the amount of turns in the secondary: Voltage secondary/voltage primary=number of turns in secondary/ number of turns in primary. using some algerbra we can solve for number of turns in secondary: (Voltage secondary/voltage primary)*number of turns in primary=number of turns in secondary
(40V/120V)*75turns=number of turns in secondary
number of turns in secondary=25turns
Answer:
cause of the g force pushing u back
Explanation:
Answer:
D or A ( I think)
Explanation:
Cause you know how people say the smaller the chips the more the chips its kind of the same with amplitude.
( hope it helps if I am wrong I am sorry)
Answer:
x=0.01457 m
Explanation:
From parallel axis theorem
I=Icm+mh²
where h=x
The rotational inertia about its center of mass is
Icm=mL²/12
where L=1.0 m
Thus T=4.8s we obtain
After Solving this quadratic we get
x₁=5.702 m
x₂=0.01457 m
One of the solution is an impossible value for x (x=5.70m is greater than L)
So we choose the other one
x=0.01457 m
