Answer:
16.7 mF
Explanation:
The total capacitance of two capacitors connected in series is given by the formula:

in our problem, we have:
C1 = 45 mF is the capacitance of the first capacitor
C2 = 26 mF is the capacitance of the second capacitor
Substituting into the equation, we find:

I hope that helps you!!!!!!
Answer:
1.26 m/s²
Explanation:
Given:
Δx = 172 m
v₀ = 17.3 m/s
v = 27.1 m/s
Find: a
v² = v₀² + 2aΔx
(27.1 m/s)² = (17.3 m/s)² + 2a (172 m)
a = 1.26 m/s²
