Advantage of series circuit :
1. allows all the components in the circuit to have same current flowing through them.
2. one switch is enough to turn off all the components in the circuit in series.
3. make the circuit small by using smaller length of wire.
Disadvantages of series circuit :
1. If one component becomes defective , it does not allow other components to operate, since they share same current.
2. all components can not have same voltage across them.
Answer:
a) t = 1.75 s
b) x = 31.5 m
Explanation:
a) The time at which Tom should drop the net can be found using the following equation:
Where:
: is the final height = 0
y₀: is the initial height = 15 m
g: is the gravity = 9.81 m/s²
: is the initial vertical velocity of the net = 0 (it is dropped from rest)
Hence, Tom should drop the net at 1.75 s before Jerry is under the bridge.
b) We can find the distance at which is Jerry when Tom drops the net as follows:
Then, Jerry is at 31.5 meters from the bridge when Jerry drops the net.
