To determine the required magnitude of the buoyancy force acting on the bronze weight, we use the formula: Fa = ρker * g * V = ρker * g * m / ρbr.
Data: ρker – kerosene density (by condition ρker = 8 * 10 ^ -2 kg / m3); g – acceleration of gravity (g = 9.81 m / s2); m is the mass of the bronze weight (m = 1 kg); ρbr is the density of bronze (according to the condition ρbr = 8.8 * 10 ^ 3 kg / m3).
Calculation: Fa = ρker * g * m / ρbr = 8 * 10 ^ -2 * 9.81 * 1 / (8.8 * 10 ^ 3) = 0.892 N.
Answer: A buoyancy force of 0.892 N. acts on the bronze weight.
