Answer:Explanation:
Image result for what does a worm and wheel mechanism do to torque and speed
Like other gear arrangements, a worm drive can reduce rotational speed or transmit higher torque. ... Each full 360 degree turn of a single start worm advances the gear by one tooth. For a multi start worm the gear reduction equals the number of teeth on the gear divided by the number of starts on the worm.
Explanation:
the correct answer is Option 5.√½gh.
hope this helps you.
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: It would be 125 J
D
Its D i think because it doesnt refer to any other things
