Boat speed is 68km/h both to and fro.
boat b speed to is 34km/h and back is 102km/h
time taken by boat to is distance/speed= 68 km/68km/h=1 hour
and fro is 68km/68km/h=1 hour
for the whole trip boat a took 2 hours
boat b speed to is 34km/h and distance is 68km, so it took 68km/34km/h = 2 hours to and fro it took 68km/102km/h=0.67 hours
for the whole trip boat b took 2.67 hours
so boat a is the winner as it took 2 hours to complete the challenge.
Answer:
A circuit with two 10 ohm resistors connected in series.
Explanation:
The formula for the equivalent resistance for resistors in parallel is
So if R1=R2= 10 
The formula for the equivalent resistance for resistors in series is
Rt = R1 + R2 So Rt= 10 + 10 = 20
Answer:
The angular velocity is: (2π radians) ⁄ (4.3 sec) = 1.461 rad/sec
The angular displacement is: (1.461 rad/sec)(1 sec) = 1.461 radians
