What object?? There is no pic
Answer:
A cylinder's volume is π r² h, and its surface area is 2π r h + 2π r².
Angle 10 is 140 degrees
Angle 2 = Angle 10 = 140 degrees (Vertically Opposite Angles)
Angle 5 + Angle 4 = Angle 2 (Corresponding Angles)
Angle 5 + Angle 4 = 140
90 + Angle 4 = 140 (Angle 5 is 90 degrees because c is perpendicular to d)
Angle 4 = 50
The third option can be represented by a linear function, y = -8x + 6.
Induced emf = -NA (ΔФ/Δt)
N = 1 (assuming its 1 loop), ΔФ = 0.2-0 = 0.2 T, Δt = 0.3 sec, A = 0.12 m^2
Therefore,
Induced emf = -1*0.12*(0.2/0.3) = -0.08 V
