<em>Cartilaginous joints</em> is not a functional classification for joints.
Answer: Option 2
Explanation:
The joints are classified based upon their <em>structure and function</em>. Based upon the composition as well as presence or absence of the cavity, the joints are <em>structurally</em> classified as:
- Fibrous joints
- Cartilaginous joints
- Synovial joints
On the other hand, based upon the functions performed by the joints, the <em>functional </em>classification of joints are as follows:
- Diarthrosis
- Amphiarthrosis
- Synarthrosis
Thus it is inferred that, cartilaginous joint is structural classification of joints, not functional.
Answer:
Mass of first objects, m₁= 100 g = 0.1 kg
Mass of second object, m₂ = 200 g = 0.2 kg
Velocity of m₁ before collision, v₁= 2 m/s
Velocity of m₂ before collision, v₂ = 1 m/s
Velocity of m₁ after collision, v₃ = 1.67 m/s
Velocity of m₂ after collision = v₄
According to the law of conservation of momentum:
Total momentum before collision = Total momentum after collision
m₁v₁ + m₂v₂ = m₁v₃+ m₂v₄
⇒ 0.1 * 2 + 0.2 * 1 = 0.1 * 1.67 + 0.2 * v₄
⇒ 0.4 = 0.67 + 0.2 * v₄
