Answer:
The answer for "which one is bridge animal?" is 4. I think it is i and ii not ii and ii.
The answer for the homologous organ is forelimb of seal.
The vestigial organ is appendix.
A greater fraction of kinetic energy is lost from the system during the collision when the speed of the first cart is greater due to inelastic collision.
<h3>What is kinetic energy?</h3>
It should be noted that kinetic energy simply means a form of energy of an object due to motion.
In this case, a greater fraction of kinetic energy is lost from the system during the collision when the speed of the first cart is greater due to inelastic collision.

The acceleration of the pendulum mass D is; r"_d = [x''(t) + lθ'' cos θ - lθ'² sin θ]i - l[θ'' sin θ - θ'² cos θ]j
<h3>What is Kinematics of particles?</h3>
Kinematics is the study of the geometry of motion of particles, rigid bodies, etc., disregarding the forces associated with these motions. However, Kinematics of a particle is the motion of a point in space.
From the sample problem, we can solve it using the (x, y, z) coordinate system to get;
r_c = x(t) i
r_d = [x(t) + l sin θ]i + l cos θ j
Finding the first derivative of r_d gives velocity as;
r'_d = [x'(t) + lθ' cos θ]i - lθ' sin θ j
Taking the second derivative of r_d gives the acceleration as;
r"_d = [x''(t) + lθ'' cos θ - lθ'² sin θ]i - l[θ'' sin θ - θ'² cos θ]j
A sample problem of kinematics of particles is;

An unsaturated solution is formed when 80. Grams of a salt is dissolved in 100. Grams of water at 40. °c. This salt could be.
Solubility is the maximum amount of soluble solid that can be dissolved in a 100-gram of water at a specific temperature. The solubility of a compound is directly proportional to the temperature which means that more solids can be dissolved at a higher temperature. Moreover, a solution which has a concentration below its solubility is an unsaturated solution. When both concentration and solubility are the same, then the solution is saturated. Lastly, when the concentration of a solution is higher than the solubility at a specific temperature, then the solution is called supersaturated.
