Answer:
75.5g
Explanation:
From the ionic equation, we can write
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
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
Hence the amount of copper produced is 75.5g
Light travelling in a vacuum is the fastest thing in the universe. The speed would be 2.99x10^8 m/s. The answer to this question is 'vacuum', where light can travel the fastest. I hope this helps you. You're welcome!
They can either cancel each other or add up to a resultant force with a certain direction and modulus.
Newton's second law states that F=m*a, where F is the resultant force, ie ΣF.

Answer:
72.22 N
Explanation:
F = weight
m = mass of body
M = mass of earth
R = radius of earth
G = universal constant of gravitation
F_1= 650 N
F_1 = GMm/R^2
two earth radius above the surface of the earth:
F_2= GMm/(3R)^2= GMm/9R^2= F_1/9= 650/9
=72.22 N
