Answer:60 ohms
Explanation:
R1=30 ohms
R2=15 ohms
R3=15 ohms
Let the total resistance be R
R=R1 + R2 + R3
R=30 + 15 +15
R=60
Total resistance is 60 ohms
Answer:
At the end points of motion (either side) the velocity must be zero because the velocity is changing from - to + (it can't turn around around without passing thru zero,
The velocity will then increase to the midpoint of the motion.
m g h = 1/2 m v^2 where h is the vertical distance thru which the pendulum travels

Explanation:
It is given that,
Speed of the jet airplane with respect to air, 
If the wind at the airliner’s cruise altitude is blowing at 100 km/h from west to east, 
(A) Let 
is the speed of the airliner relative to the ground if the airplane is flying from west to east,
(B) Let 
is the speed of the airliner relative to the ground if the airplane is flying from east to west,
Hence, this is the required solution.
