3. in which instruments you can see oscillatory motion?

4. distinguish between linear and random motion


pls ans ​

Answer 1

Answer:

1. Speed is a scalar quantity that refers to "how fast an object is moving." Speed can be thought of as the rate at which an object covers distance. A fast-moving object has a high speed and covers a relatively large distance in a short amount of time.

2. The formula for speed is speed = distance ÷ time. To work out what the units are for speed, you need to know the units for distance and time. In this example, distance is in meters (m) and time is in seconds (s), so the units will be in meters per second (m/s).

3.All the musical instruments which have strings, for example guitar, violin etc. execute the oscillatory motion. The object is said to be in oscillatory motion when it moves to and fro in same direction.When we hit the strings of guitar or violin, they move to and fro. This means that, they execute oscillations. These oscillations generate the music out of the instruments.This motion of the strings of the instruments is same as that of the swing. 

4.Linear motion is a one-dimensional motion along a straight line, and can therefore be described mathematically using only one spatial dimension. ... Random Motion is a motion in which an object didn't go in a straight manner, the object move in a zig zag manner.
