2 is correct hope you get it right
The branch of science which deals with celestial objects, space, and the physical universe as a whole.
Online definition so if you’re using it for school work I recommend re-wording!
<em>Average velocity is defined as the ratio of change in position to the time taken for that change. </em>
Answer: <em>True</em>
Explanation:
Velocity is obtained by dividing the displacement of an object by time interval. Displacement is a vector quantity which is defined as the shortest distance between initial and final point of an object.
In other words, displacement is the change in position of an object. A position-time graph can be plotted to find the average velocity of an object graphically. The average velocity can be obtained by calculating the slope of the position-time graph.
While average velocity deals with velocity over a particular time interval, instantaneous velocity gives the velocity of an object at a particular point of time or instant.
Answer:
Explanation:
It is given that two identical masses is attached to the either end of the spring
with spring constant k
angular frequency of the system is given by
here
Thus
