Answer:
Mercury has the lowest melting point.
Answer:
136 N
Explanation:
Pressure on large piston = pressure on small piston
F₁ / A₁ = F₂ / A₂
1700 N / 1.5 m² = F / 0.12 m²
F = 136 N
Physics is the fundamental (basic) science because all other sciences are derived from Physics.
12 mg = 0.012 g
12 mg = 1.2e-5 kg
75 kg = 75,000 g
