A complex machine is a machine made up of two or more simple machines that make your work easier to do. There are six simple machines from which all complex machines are made. They include: The lever. The inclined plane
Answer:
Va = 5000 m / 3600 s = 1.39 m/s
(Va - Vb) 60 = 10
Vb = Va - .167 = 1.22 m/s
(Va - Vb) T = 4200 Π where T is time for A to complete 1 more lap
.17 T = 4200 Π
T = 24700 Π time for A to again catch B
N = 1.39 * 24700 Answer:
Va = 5000 m / 3600 s = 1.39 m/s
(Va - Vb) 60 = 10
Vb = Va - .167 = 1.22 m/s
(Va - Vb) T = 4200 Π where T is time for A to complete 1 more lap
.17 T = 4200 Π
T = 24700 Π time for A to again catch B
N = 1.39 * 24700 Π / (4200 Π) = 8.2 laps
A will make 8 but not 9 rounds before catching B

Answer:
The mmf required is 
×
A
Explanation:
The Magnetomotive force (mmf) is given by the formula below
where 
is the Magnetomotive force (mmf)
is the Magnetic field strength
is the magnetic length
The magnetic permeability μ is given by
μ = 
Where 
is the Magnetic flux density
and is the Magnetic field strength
From the question,
= 1.2Wb/m^2
μ = 1600m
From μ =
∴
μ
× 
A/m
Now, for the Magnetomotive force (mmf)
From the question
= 1.5 m
∴ 
× × 
×
Hence, The mmf required is × A
