Answer:
V₅ = 20 V
Explanation:
Given that
Total voltage ,V= 120 V
Given that resistor are connected in series that is why the total voltage drop will be summation of voltage drop in the all resistor.
V₁=Voltage drop on first resistor
V₂=Voltage drop on second resistor
V₃=Voltage drop on third resistor
V₄=Voltage drop on forth resistor
V₅=Voltage drop on fifth resistor
Therefore
V= V₁+V₂+V₃+V₄+V₅
120 = 35 + 28 + 22 + 15 + V₅
V₅ = 20 V
Therefore the voltage drop on the fifth resistor will be 20 V.

Explanation:
Answer:
time is 2 hour and 32 min
Explanation:
given data
normal average speed = 105 km/h = (65 mi/h)
trip time takes = 1 h and 50 min = 1.83 hr
average speed with heavy traffic = 75.0 km/h = (47 mi/h )
to find out
How much longer does the trip take
solution
we know that here total distance that is express as
Total distance = Average speed × Total time ..................1
Total distance = 105 × 1.83
Total distance = 192.15 km ( distance between San Diego and Los Angeles )
and when average speed 75 km/h
time will be
time =
time =
time = 2.56 hr
so time is 2 hour and 32 min
