kinda just re-worded the stuff I saw on google
Answer:
Stringed instruments (chordophones).
Explanation:
Musical instruments that produce sound by vibration of a stretched string are called stringed instruments (chordophones).
Some examples of stringed instruments are guitar, piano, harp, violin, sitar etc.
A guitar can be defined as a musical instrument with six or twelve strings and a long fretted fingerboard that are being played using a plectrum or by strumming (plucking) with the fingers, usually in a downward direction.
Basically, a guitar is a musical instrument that produces sound through regular vibrations and as a result of this, it is used for creating uniform and melodious sounds.
The correct choice is :
The final momentum of the bullet/block is equal to the initial momentum of the bullet.
initially the block was at rest , hence
initial momentum of the block = 0
so total initial momentum was simply equal to initial momentum of bullet only.
after collision , the bullet gets embedded in the block , and hence both block-bullet move together at common velocity . according to conservation of momentum , momentum remains conserved in any type of collision.
so final momentum of bullet-block system = initial momentum of bullet
Answer and explanation:
Let be the velocity of a body projected vertically up, 1 second before it reaches its maximum height. We know, from the kinematics equations, that the distance traveled in an interval of time is equal to:
Then, in the last second, the distance traveled is equal to:
But the velocity is related to the time by the equation:
And substituting this expression in the equation above, we obtain:
It means that the distance traveled by the body in the last second of its motion is a constant, independent of its initial velocity.
Tf kinda question is that? But it’s because at first they sink, but as they decompose and and gasses are released in the body, as a result of buoyancy, it floats.
