Answer:
Before collision:
momentum to right = .14 * 3.5 = .49 kg m / s
momentum to left = .62 * 4.81 = 2.98 kg m / s
Total momentum = .49 - 2.98 = - 2.49 to left
M V = -2.49 net momentum to left
V = -2.49 / (.14 + .62) = -3.28 m/s to left
Answer:
Breh seriously. Ugh fine.

Answer: +2.10V
Explanation:
Using Nernst equation :
where,
= standard emf for the cell = +2.20 V
n = number of electrons in oxidation-reduction reaction = 6
= emf of the cell = ?
= concentration =
= concentration =
Now put all the given values in the above equation, we get:
The standard emf for the cell using the overall cell reaction below is +2.10 V
