Answer:
Step-by-step explanation:
v=Q-P
v=(5,1,0)
u=v/(magnitude of v)=(5,1,0)/(\sqrt{5^2+1^2+0^2)
u=(5/5.09,1/5.09,0)
v=Q-P
v=(1,1,0)
u=v/(magnitude of v)=(1,1,0)/(\sqrt{1^2+1^2+0^2)
u=(1/
,1/
,0)
There's an app called photomath that would be useful for these kinds of problems!
Sorry for not giving you the calculation here -
5/12 and 2/9 have denominators divisible by only 3 right? Well The common denominator that can then change is 3 because that's the only number they have in common (except 1)
Answer:
Copper is being reduced
Step-by-step explanation:
Since the charge of the copper ion went down (2+ --> 0), we can say that Copper is being reduced. An atom is reduced when electrons are added.
