How is mechanical advantage determined in a pulley system?

Physics
1 answer:
ratelena [41]3 years ago
7 0

Answer:

<h3>To calculate the mechanical advantage of a pulley you simply have to count the number of rope sections that support whatever object you are lifting (not counting the rope that is attached to the effort). For example, in a one pulley system the MA is 1. ... The more compound the pulley is the easier the load is to lift.</h3>

a current of 250 amps is flowing through a copper wire with resistance of 2.09 x 10^4 ohms. what is the voltage
Dima020 [189]

V = I · R

Voltage = (current) · (Resistance)

Voltage = (250 A) · (2.09 x 10⁴)

Voltage = 5,225,000 volts .

I may be out of line here, but I'm pretty sure
that the resistance is 2.09 x 10⁻⁴ .
Then

Voltage = 0.05225 volt (not 5 million and something)

580 nm light shines on a double slit
Helga [31]

Answer:

0.532

Explanation:

Your equation to find the second bright interference maximum is gonna be this: d sin (Θ) = m λ

First, find your variables.

λ = 580 · 10^-9

d = 0.000125

m = 2

Next, fill in the equation.

d sin (θ) = m λ

(0.000125) sin (θ) = (2) (580·10^-9)

Then isolate your variable.

θ = arcsin ( (2)(580·10^-9) / (0.000125) )

Run your equation and you will end up with 0.53171246 , which rounds to 0.532.

The main thing you have to watch out for is make sure you are calculating for the bright interference and not the dark interference, as well as checking you're calculating for the maximum, not the minimum.

I hope this helps :D
