Explanation:
for 40hz
since they are in series they will have the same amper
so R=30ohm
C=30F
for 50Hz
R=25
C=25

I dont understand what your asking here.

Answer:
the estimated time of submersion is 17.7 years
Explanation:
Given the data in the question;
estimate the time of submersion in years.
we write down the relation between time of submersion and corrosion penetration as follows;
CPR(mpy) = K × W(mg) / [ A(in²) × p(g/cm³) × t(hr) ]
we solve for t
t = (K × W) / ( AP × CPR )
given that;
Area A = 5 in²
W = 2.3 kg = 2.3 × 10⁶ mg
density of steel p = 7.9 g/cm³
CPR = 200
we know that K is 534
so we substitute
t = (534 × 2.3 × 10⁶ mg) / ( 5 in² × 7.9 g/cm³ × 200 mpy )
t = 1,228,200,000 / 7900
t = 155468.3544 hr
t = 155468.3544 hr × ( 1 yrs / ( 365 × 24 hrs )
t = 17.7 years
Therefore, the estimated time of submersion is 17.7 years
Answer:
Engineers are people that design and create things to better the human and natural worlds.Engineers Create Buildings and structures that serve different purposes One could be an architect someone who designs buildings, or maybe a mechanical engineer and create refrigerators and phones.

Explanation:
The transferred energy calculations can be done using the equation:
This is when:
• power is calculated in watts (W)
• energy is calculated in joules (J)
• time is calculated in seconds (s)
it can also be calculated by utilizing the same equation but with different units:
• when energy is measured in kilowatt-hours (kWh)
• when power is measured in kilowatts (kW)
• and when time is measured in hours (h)
