Answer:
¢
Step-by-step explanation:
Given that:
Mass of metal = 12g = 0.012
Density of metal = 4 g/cm³ = 4000kg/m³
Density of oil = 1.5g/cm³ = 1500 kg/m³
Recall : density = mass / volume
Volume of metal, V = mass / density = 0.012/ 4000 = 0.000003
0.000003
T + Density of oil * g * V - (0.012 * 9.8) = 0
T + 1500 * 9.8 * 0.000003 - 0.1176 = 0
T = 0.0441 - 0.1176 = 0
T = 0.1176 - 0.0441
T = 0.0735N
Tension, T
