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
An airplane has a large amount of kinetic energy in flight due to its large mass and fast velocity.
D)
Explanation:
Coz the position changes with time but the position change is not constant throughout time So, D) does not have constant velocity
