Divide the distance traveled (0.30 km) by the travel time (0.50 hrs) and get the speed in km/hr. The direction is due west. 60 km/hr west
Answer:
0.000314 Am²
6.049*10^-7 T
Explanation:
A
From the definitions of magnetic dipole moment, we can establish that
= , where
= the magnetic dipole moment in itself
= Current, 100 A
= Area, πr² (r = diameter divided by 2). Converting to m², we have 0.000001 m²
On solving, we have
= ,
= 100 * 3.14 * 0.000001
= 0.000314 Am²
B
=
(0)/4
* 2
/
³, where
(0) = constant of permeability = 1.256*10^-6
z = 4.7 cm = 0.047 m
B = 1.256*10^-6 / 4*3.142 * [2 * 0.000314/0.047³]
B = 1*10^-7 * 0.000628/1.038*10^-4
B = 1*10^-7 * 6.049
B = 6.049*10^-7 T
<span>The speeds of a modern turbine that has blades that are 56 m long averages around 40 mph. It varies by how much rpm's it uses at the given time. The lower the rpm's, the lower mph it will be. Likewise, the higher the rpm's, the higher mph is will be.</span>
