A textbook but if there none to good use try google
Answer:
c) All choices listed are definitely true.
Explanation:
a)
- As they are connected in parallel, the voltage drop is equal in all the resistors, by definition of a parallel connection, and equal to the terminal voltage of the battery (assuming that the internal resistance of the battery is negligible).
b)
- Applying Ohm's law to the circuit, we arrive to the following expression:
- Simplifying common terms, we have:
- It can be seen that the equivalent resistance, is less than any of the resistances.
d)
- Due to the charge conservation principle, as the current is made from moving charges, the sum of the currents passing through these resistors is equal to the current passing through the battery (KCL).
Answer:
It is less than 25m/s as the correct average is 24m/s.
Explanation:
This is becuase you need to take the average of the two speeds (18m/s and 30m/s) 18 + 30 divided by 2 is 24m/s.
