How often would you push someone on a swing to create a frequency of .4 hertz

1 answer:

4 0

The unit "Hertz" means "per second".

Anything happening with a frequency of 0.4 Hz is happening 0.4 per second.

Technically, you must push the swing 0.4 times per second.
But since it's very hard to push 0.4 of one time, you have to be
able to figure out that you should push once every 2.5 seconds.

(1 push / 2.5 sec) = (1/2.5) push/sec = 0.4 per sec = 0.4 Hz .

If an electric current of 8.50 A flows for 3.75 hours through an electrolytic cell containing copper-sulfate (CuSO4) solution, t

muminat

Answer:

75.5g

Explanation:

From the ionic equation, we can write

$CU^{2+}+SO^{2-}_{4}\\$

next we find the number of charge

Note Q=it

for i=8.5A, t=3.75 to secs 3.75*60*60=13500secs

hence

$Q=8.5*13500\\Q=114750C$

Since one faraday represent one mole of electron which equal 96500C

Hence the number of mole produced by 114750C is

114750/96500=1.2mol

The mass of copper produced is

$mol=\frac{mass}{molar mass} \\mass=mole*molar mass\\mass=1.2*63.5\\mass=75.5g$

Hence the amount of copper produced is 75.5g
