-- If the four light bulbs are in <u><em>series</em></u>, then the total resistance becomes <em>four times as much</em> as it was with a single bulb, because now, the current has to push through one light bulb four times.
-- If the four light bulbs are in <u><em>parallel</em></u>, then the total resistance becomes <em>1/4 as much</em> as it was with a single bulb, because now, the current can split up into four equal streams, and each stream only has to push through a single light bulb.
Answer:
i would say the third one

Answer:
speed of the spaceship is 0.495251 c
Time T = 1.4982 hr
Explanation:
given data
length L1 = 1600 m
length L2 = 1390 m
to find out
speed of the spaceship and time
solution
we know here
L2 = L1 × 
so we find V by put L1 and L2
1390 = 1600 ×
V = 0.495251 c
speed of the spaceship is 0.495251 c
and
we know T1 = 1.95 hr
so we find T2
T1 = T2 
put here V and T1 so we get T2
1.95 = T2 
Time T = 1.4982 hr
