Answer:
8 mph, 12 mph
Explanation:
t = Time taken = 7 hours
x = Speed of Randall
x+4 = Speed of Gregory
The distance they both will travel together is 140 miles if they start at the same time.
The speed of Randall is 8 mph
The speed of Gregory is 8+4 = 12 mph
Explanation:
Given that,
Two resistors 4.5 Ω and 2.3 Ω .
Potential difference = 30 V
When they are in series, the current through each resistor remains the same. First find the equivalent resistance.
R' = 4.5 + 2.3
= 6.8 Ω
Current,
So, the current through both lightbulb is the same i.e. 4.41 A.
When they are in parallel, the current divides.
Current flowing in 4.5 resistor,
Current flowing in 2.3 ohm resistor,
In parallel combination, are brighter than bulbs in series.
