Answer:
Explanation:
i) On a cold day, Capacity = (66 X 910 X 10∧-9) F
Charge, Q = (66 X 910 X 10∧-9) X 5050 = 0.30 Columb
Current, I= 5050/131013 = 0.039 Amp (where Resistance = 131013 ohms)
Time, t= 0.30/0.039 = 7.7 seconds
ii) On a humid day, Capacity = (77 X 910 X 10∧-9) F
Charge, Q = ( 77 X 910 X 10∧-9) X 5050 = 0.35 Columb
Current, I= 5050/6106 = 0.83 Amp ( where Resistance = 6106 ohms)
Time, t= 0.35/0.83 = 0.42 h or 0.42 X 60 mins = 25 mins
Answer:

Explanation:
Given

Required
Write an equivalent expression in C
The given expression uses + and + is represented as + in C
So: The equivalent expression is

However, C supports compound assignment operators
So:
can be rewritten as

I’m not 100% sure but I think it’s a padlock that represents it
