Answer:
√2
Explanation:
If the final kinetic energy is 2 times the initial kinetic energy:
KE = 2 KE₀
½ mv² = 2 (½ mv₀²)
v² = 2 v₀²
v = √2 v₀
Therefore, the ratio of the final momentum to the initial momentum is:
p / p₀
mv / (mv₀)
v / v₀
√2
Answer:
true
Explanation:
Answer:
When the object is moving in a straight line distance will be equal to displacement. ... Shortest path = Actual path,because object travelled in a straight line. Displacement and Distance should have same magnitude because the object has not changed its direction.
Explanation:
The diagram of the working principle of scrap heap magnet is in the image uploaded.
The scrap heap magnet is a complex or large electromagnet that is powered by a very large battery.
The working principle of a scarp heap magnet is the same as an ordinary electromagnet. The thick insulated copper wire is wound around a soft iron core. When current is allowed to pass through, it becomes very strong and attracts all the magnetic materials in the scrap.
