Longitudinal wave hope this is right :))))))))))
200N is the answer (at least thats what I think)
Answer:
−1.9 × 10−5 Wb
Explanation:
Magnetic flux is the product of average magnetic field times the perpendicular area that is crosses times the angle between planar area and magnetic flux
Finding the area
Area = πr² = 3.14*0.075*0.075
Area=0.01767 m²
Magnetic flux = 0.01767*0.00110*cos 0
Magnetic flux =0.000019 = −1.9 × 10−5 Wb
Answer:
1. Simply τ = m x g x r = 54kg x 9.8m/s² x 0.050m = 26 N·m
2. The bucket creates a torque
τ = 75kg x 9.8m/s² x 0.075m = 55 N·m,
so we must create the same torque with the handle.
55 N·m = F x 0.25m
F = 220 N
