Answer:
Radius of circular sheet (r₁) = 4 cm
Radius of circular sheet (r₁) = 4 cmRadius of removed circle (r₂) = 3 cm
Radius of circular sheet (r₁) = 4 cmRadius of removed circle (r₂) = 3 cmArea of remaining sheet = Area of circular sheet – Area of removed circle = πr₁2 - πr₂2
Radius of circular sheet (r₁) = 4 cmRadius of removed circle (r₂) = 3 cmArea of remaining sheet = Area of circular sheet – Area of removed circle = πr₁2 - πr₂2= π (r₁2 - r₂2)
Radius of circular sheet (r₁) = 4 cmRadius of removed circle (r₂) = 3 cmArea of remaining sheet = Area of circular sheet – Area of removed circle = πr₁2 - πr₂2= π (r₁2 - r₂2)= 3.14 (42 - 32) cm2
Radius of circular sheet (r₁) = 4 cmRadius of removed circle (r₂) = 3 cmArea of remaining sheet = Area of circular sheet – Area of removed circle = πr₁2 - πr₂2= π (r₁2 - r₂2)= 3.14 (42 - 32) cm2 = 3.14 (16 - 9) cm2
Radius of circular sheet (r₁) = 4 cmRadius of removed circle (r₂) = 3 cmArea of remaining sheet = Area of circular sheet – Area of removed circle = πr₁2 - πr₂2= π (r₁2 - r₂2)= 3.14 (42 - 32) cm2 = 3.14 (16 - 9) cm2 = 3.14 × 7 cm2
Radius of circular sheet (r₁) = 4 cmRadius of removed circle (r₂) = 3 cmArea of remaining sheet = Area of circular sheet – Area of removed circle = πr₁2 - πr₂2= π (r₁2 - r₂2)= 3.14 (42 - 32) cm2 = 3.14 (16 - 9) cm2 = 3.14 × 7 cm2 = 21.98 cm2
Radius of circular sheet (r₁) = 4 cmRadius of removed circle (r₂) = 3 cmArea of remaining sheet = Area of circular sheet – Area of removed circle = πr₁2 - πr₂2= π (r₁2 - r₂2)= 3.14 (42 - 32) cm2 = 3.14 (16 - 9) cm2 = 3.14 × 7 cm2 = 21.98 cm2Thus, the area of the remaining sheet is 21.98 cm2.
Find the area of the remaining sheet. (Take π = 3.14) Thus, the area of the remaining sheet is 21.98 cm2.
Answer:
This relationship, known as Faraday's law of induction (to distinguish it from his laws of electrolysis), states that the magnitude of the emf induced in a circuit is proportional to the rate of change of the magnetic flux that cuts across the circuit.
