Answer:
To write the general formula for an acid, we fix one atom which is hydrogen because this atom is common to all the acids. General formula for acid is written by HX. where H represents Hydrogen atom.

Steps 1 and 2)
The variables are W = work, P = power, and t = time. In this case, W = 9514 joules and P = 347 watts.
The goal is to solve for the unknown time t.
-----------------------
Step 3)
Since we want to solve for the time, and we have known W and P values, we use the equation t = W/P
-----------------------
Step 4)
t = W/P
t = 9514/347
t = 27.4178674351586
t = 27.4 seconds
-----------------------
Step 5)
The lawn mower ran for about 27.4 seconds. I rounded to three sig figs because this was the lower amount of sig figs when comparing 9514 and 347.

Note: we don't use the mass at all
Answer:
E) 6.5 A
Explanation:
Given that
L = 40 m H
C= 1.2 m F
Maximum charge on capacitor ,Q= 45 m C
The maximum current I given as
I = Q.ω
ω =angular frequency
![\omega=\dfrac{1}{\sqrt{CL}}](https://tex.z-dn.net/?f=%5Comega%3D%5Cdfrac%7B1%7D%7B%5Csqrt%7BCL%7D%7D)
By putting the values
![\omega=\dfrac{1}{\sqrt{CL}}](https://tex.z-dn.net/?f=%5Comega%3D%5Cdfrac%7B1%7D%7B%5Csqrt%7BCL%7D%7D)
![\omega=\dfrac{1}{\sqrt{40\times 10^{-3}\times 1.2 \times 10^{-3}}}](https://tex.z-dn.net/?f=%5Comega%3D%5Cdfrac%7B1%7D%7B%5Csqrt%7B40%5Ctimes%2010%5E%7B-3%7D%5Ctimes%201.2%20%5Ctimes%2010%5E%7B-3%7D%7D%7D)
ω = 144.33 rad⁻¹
Maximum current
I = 45 x 10⁻³ x 144.33 A
I= 6.49 A
I = 6.5 A
E) 6.5 A
