Explanation:
Answer:
The more hydrogen bonds a molecule can make, the higher the surface tension.
Explanation:
Hydrogen bonds provide higher surface tension to a liquid
More hydrogen molecules - stronger cohesive forces
Momentum:
p₁ = m₁v₁
p₂ = m₂v₂
p₃ = (m₁+ m₂) v
p₁ + p₂ = p₃
v = p₁ + p₂ / (m₁ + m₂)
friction:
F = μ(m₁ + m₂)g = (m₁ + m₂)a ⇒ a = μg
equations of motion:
v = at = μgt ⇒ t = v/μg
x = 1/2 at² = 1/2 μg * v²/(μg)² = 1/2 v² / μg
v₁ = 300 m/s
v₂ = 0 m/s
m₁ = 0.004 kg
m₂ = 0.8 kg
μ = 0.3
g = 9.81 m/s²
x = displacement
