Completing the sentence given ; Only the most reactive metals react with<u> water</u>
Reactivity of metals is a chemical property that measures the rate at which metals easily loses their electrons in substances to form a positive ion in a substance.
The most reactive metals react vigorously with water while the least reactive metals does not react with water and dilute acids vigorously but they slowly react with oxygen.
Examples of very reactive metals are :
- Potassium
- sodium and
- Lithium
Hence we can conclude that Only the most reactive metals react with<u> </u>water.

Explanation:
From the question we are told that
The length of the wire is 
The current is 
The magnetic field strength is 
The magnitude of the magnetic force is 
Generally the magnetic force exerted on the wire is mathematically represented as

Answer:
The phrases the describe the situation are A and C
Explanation:
1- If a car is at rest or uniform motion, it will remain in that condition until an external force acts on it. If the external forces acting on a body are balanced , it means that their sum is equals to 0, which eventually results that no Net force is acting on it.
For balance forces, ∑F = 0
2- If the car moving at a constant speed is slowing down, it means that the forces have become unbalanced, eventually resulting in a Net force in the opposite direction of the motion of the car, due to which it is slowing down
For unbalanced forces, ∑F ≠ 0
The question satisfies 2, which is the answer
