Answer:
The maximum velocity is 0.489 m/s
Explanation:
Maximum velocity (v) = angular velocity (w) × radius (r)
w = 33.33 rpm = 33.33×0.1047 = 3.4897 rad/s
r = 14 cm = 14/100 = 0.14 m
v = 3.4897×0.14 = 0.489 m/s
Answer: a disadvantage of using a ramp is that it is not safe
Complete Question:
In the same configuration of the previous problem 3, four long straight wires are perpendicular to the page, and their cross sections form a square of edge length a = 13.5 cm. Each wire carries 7.50 A, and the currents are out of the page in wires 1 and 4 and into the page in wires 2 and 3.
a) Draw a diagram in a (x,y) plane of the four wires with wire 4 perpendicular to the origin. Indicate the current's directions.
b) Draw a diagram of all magnetic fields produced at the position of wire 3 by the other three currents.
c) Draw a diagram of all magnetic forces produced at the position of wire 3 by the other three currents.
d) What are magnitude and direction of the net magnetic force per meter of wire length on wire 3?
Answer:

The statement that best describes how the windmill technology benefits the environment is this: WINDMILLS DO NOT POLLUTE THE ENVIRONMENT.
Constructing a windmill involves harnessing the power of the wind to generate electricity. This type of electricity generation has no side effects whatsoever. It is environmental friendly and does not pollute the environment.
