Answer:
The conservation of momentum states that, within some problem domain, the amount of momentum remains constant; momentum is neither created nor destroyed, but only changed through the action of forces as described by Newton's laws of motion. ... Momentum is conserved in all three physical directions at the same time.
Answer: Option (d) is the correct answer.
Explanation:
An electrolytic solution which is conductive in nature, that is, a solution that has ions or atoms.
In the given options, sports drink, sweat, and ocean water are all electrolytic solution.
Whereas pure water has pH equals to 7, that is, pure water is neutral. Thus, we can conclude that pure water is not an example of an electrolytic solution.

Answer:
6750 J
Explanation:
The specific heat capacity of iron is 450 J/kg/K
Quantity of heat = mcθ; where m is the mass and c is the specific heat capacity and θ is the temperature change.
Therefore;
m = 3 kg, c = 450 J/kg/K and θ = 5°C
Quantity of heat = 3 × 450 × 5
<u>= 6150 Joules</u>
