What is one disadvantage of a series circuit?
a. the bulbs in a series circuit will give off more heat then the same bulbs in a parallel circuit.
b. if one bulb burns out, then none of the others will light up.
c. it is difficult to tell which path an electric charge is following in a series circuit
d. only one bulb can be connected in a series circuit.

If one bulb goes out then all the others won't light up because electricity will be cut off. It's a disadvantage because in a parallel circuit if one bulb burns out all the others will still be on because they won't be affected. I hope I've helped you ☺

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer
