If all the mass of fuel and oxygen is burned to form gases of combustion, the downward velocity of these gases would be 12,505 m/s.
<h3>
Conservation of linear momentum</h3>
The principle of conservation of linear momentum states that, the total momentum of an isolated system is constant.
The downward velocity of thes gases is calculated as follows;
v1(m1 + m2) = v2(m2)
305(1000 + 25) = v2(25)
312,625 = 25v2
v2 = 312,625/25
v2 = 12,505 m/s
Thus, If all the mass of fuel and oxygen is burned to form gases of combustion, the downward velocity of these gases would be 12,505 m/s.

Answer:
Stretch in the spring = 0.1643 (Approx)
Explanation:
Given:
Mass of the sled (m) = 9 kg
Acceleration of the sled (a) = 2.10 m/s
²
Spring constant (k) = 115 N/m
Computation:
Tension force in the spring (T) = ma
Tension force in the spring (T) = 9 × 2.10
Tension force in the spring (T) = 18.9 N
Tension force in the spring = Spring constant (k) × Stretch in the spring
18.9 N = 115 N × Stretch in the spring
Stretch in the spring = 18.9 / 115
Stretch in the spring = 0.1643 (Approx)
Overloading
Explanation:
The reason reason why the mcb of rupa's room keeps tripping is due to the fact that excessive current has being supplied to his room.
MCB stands for a miniature circuit breaker.
A miniature circuit breaker opens up the electrical circuit by switching it off when there is overloading or faulty connections.
- A MCB helps to control the flow of current and it is designed to hand certain limits of electrical voltage.
- If the MCB keeps tripping, it suggests a surge in current supplied, overloading or probably a faulty connection.

Answer
The nail will become an electromagnet.
Explanation
When the switched is closed , a current will flow in the insulated wire. Then the current flows through the coil around the iron nail, it will induce am magnetic filed inside the nail. The nail becomes a magnet because it is made of magnetic material. As long as there is current flowing through the current, there nail will remain a magnet.
