You have to help the person you hit and with this you hand yourself over to the authorities so that you don't get involved in a murder and save the lives of others.
Answer:
Diameter will be 27394.76 m
Explanation:
Power P = 0.5 kW = 500 W
Time t required for grinding = 1 hr = 3600 sec
Energy required E = P x t
E = 500 x 3600 = 1800000 J
Flow rate of water Q = 400 ltr/min
We convert to m3/sec
400 ltr/min = 400/(1000 x 60) m3/ses
Q = 0.0067 m3/sec
Energy provided by flow will be
E = pgQd
Where p = density of water = 1000 kg/m3
g = acceleration due to gravity 9.81 m/s2
d = diameter of wheel.
Equating both energy, we have,
1800000 = 1000 x 9.81 x 0.0067 x d
1800000 = 65.73d
d = 1800000/65.73
d = 27394.76 m
Answer:
Tension in wire will be
Explanation:
We have given seed of the transverse wave v = 400 m/sec
Linear density = 0.10 g/cm
We know that 1 gram = 0.001 kg
And 1 cm = 0.01 m
So
We know that speed of wave is given by , here T is tension in the wire
So
Squaring both side
T =
So tension in wire will be
