As the stan moves 0.94 s before with an acceleration 4.12 m/s^2
so the distance moved by it
speed gained by the car is given as
now the relative speed of them is given as
relative acceleration is given as
now the distance between them is to be covered
by solving above equation we have
so it will overtake after 6.64 s
Answer:
Total resistance is 19.6 Ω for the circuit .
Explanation:
Given:
Six resistors of a circuit namely to
.
Where
and
are in series.
and
are in parallel.
and
are in parallel.
We know that continuous resistor which are in series are added up to find the equivalent resistance.
Similarly resistors which are arranged in parallel their equivalent resistance is for the case of
and
.
According to the question:
Total resistance = R(equivalent) :
⇒
⇒
⇒
⇒
⇒ Ω
So the total resistance of the circuit depicted is 19.58 Ω approximated to nearest tenth that is 19.6 Ω
