In my opinion, a helicopter would be the quickest mode of transport, just saying.
A heavier player collides with a lighter player using greater force.
The lighter player sustains more injuries following the impact.
Explanation:
A heavier player impacts a lighter player with greater intensity, resulting in more pronounced injuries to the lighter player post-collision.
Force is defined as mass multiplied by the acceleration of an object;
Force = mass x acceleration
We observe that as mass and acceleration increase, the force exerted rises accordingly.
Clearly, the heavier player's mass surpasses that of the lighter player, leading to a greater force exerted upon collision.
Moreover, the lighter player is likely to be injured more severely after the clash. The momentum generated by the heavier player during the impact is considerably significant. Once they collide, the lighter player will certainly alter their speed and trajectory.

5.451 X 10³ kg of sodium carbonate is required to neutralize 5.04×10³ kg of sulfuric acid solution.
Explanation:
- Sodium carbonate neutralizes sulfuric acid (H₂SO₄). This compound is derived from a strong base (NaOH) and a weak acid (H₂CO₃). The chemical equation for this neutralization process is represented as:
Na₂CO₃ + H₂SO₄ ----> Na₂SO₄ + H₂CO₃
- The balanced equation indicates that one mole of Na₂CO₃ is needed to neutralize one mole of H₂SO₄.
- Molar mass of Na₂CO₃= 106 g/mol = 0.106 kg/mol, while Molar mass of H₂SO₄= 98 g/mol = 0.098 kg/mol.
- To neutralize 0.098 kg of H₂SO₄, the required Na₂CO₃ is 0.106 kg, thus, to neutralize 5.04×10³ kg of H₂SO₄, Na₂CO₃ needed is 5.451 X 10³ kg.
To determine the least degree of precision, we must base it on the mass of 4.05 kg or two decimal places. Thus, we add 0.56795 kg (0.57 kg) and 0.1001 kg (0.1 kg), resulting in a total of 4.72 kg.
<span>Conversely, to find the greatest degree of precision, we convert 4.05 kg into grams, which gives us 4050 g. Therefore, summing 4050 g with 567.95 g and 100.1 g yields 4718.05 grams, which rounds to 4718 g.</span>
The atomic number of the element indicated by the model is 8, corresponding to option 'C' in the question.
