200 newton meters is put over the distance of 20 meters, then over the distance of 10 meters 100 newton-meters must be put (simple fraction over 2).
At the same distance of 10 meters but during lifting you need to put 150 newton-meters (which means 50Nm more than during horizontal movement).
According to that you can say that the machine's advantage is horizontal movement because it does smaller work than during lifting objects. That means it consumes then less energy and then it costs less.
Answer:
7.13559 knots
Explanation:
Maximum power = 10.5 kilowatts
where,
P = Power in kilowatts
s = Desired speed in knots
Here, P = 10.5 kW
The greatest speed of the Olympians was 7.13559 knots
We have that the dipole moment in nCm is considering the <em>parameters </em>
electric field strength 1.5 cm and the axis of the dipole, is 1.5×105 N/C. is
From the question we are told
The electric field strength 1.5 cm from an electric dipole, on the axis of the dipole, is 1.5×105 N/C.

Answer:
20 m/s
Explanation:
The frictional force the road exerts on the car provides the centripetal force that keeps the car in circular motion along the curve:
where
F is the centripetal force
m is the mass of the car
r is the radius of the curve
v is the speed of the car
In this problem we have:
m = 2000 kg
r = 200 m
F = 4000 N is the maximum force
Re-arranging the equation, we can calculate the maximum speed v corresponding to this force:
Speed can be shown on a graph of position versus time, and acceleration can be shown on a graph of speed versus time.
