given,
number of cycle complete (f) = 116 cycles per minute
wavelength observed at 11 m in 1.5 m.
v = 7.33 m/s
The wavelength of the wave is equal to

Explanation:
It is given that,
Speed of the ball, v = 10 m/s
Initial position of ball above ground, h = 20 m
(a) Let H is the maximum height reached by the ball. It can be calculated using the conservation of energy as :
h' = 5.1 m
The maximum height above ground,
H = 5.1 + 20
H = 25.1 meters
So, the maximum height reached by the ball is 25.1 meters.
(b) The ball's speed as it passes the window on its way down is same as the initial speed i.e. 10 m/s.
Hence, this is the required solution.
Answer:
The force is
Explanation:
The moment of Inertia I is mathematically evaluated as
Substituting for M(Mass of the wheel) and
for
(Radius of wheel)
The torque on the wheel due to net force is mathematically represented as
Substituting 135 N for (Force acting on sprocket),
for
(radius of the chain) and F is the force acting on the sprocket due to the chain which is unknown for now
This same torque due to the net force is the also the torque that is required to rotate the wheel to have an angular acceleration of and this torque can also be represented mathematically as
Now equating the two equation for torque
Making F the subject
Substituting values
