".
Explanation:
Cavity and benzene should be extended in equal quantities.



Answer:
80m/s
Explanation:
to find it you have to work it out by using the formula distance divided by speed to find time.
Acceleration is F/M so the answer would be 12m/s^2
Answer:
F₁ = 4,120.2 N
F₂ = 3,924N
Explanation:
1) Balance of angular momentum around the end where F₁ is applied.
F₂ × 0.5m - F₁ × 0 = mass × g × 1m
⇒ F2 × 0.5 m= 20 kg × 9.81 m/s² × 1 m = 1,962 N×m
F₂ = 196.2 Nm / 0.5m = 3,924 N
2) Balance of forces
F₁ - F₂ = mg
F₁ = F₂ + mg = 3,924N + 20kg (9.81 m/s²) = 4,120.2 N
C. The membrane is inside the cell wall. The cell wall surrounds the membrane.
