Divide 14 by 6 and there is your answer with the unit of m
Answer:
d.-10.3m
Explanation:
Note for short sightedness the focal length is negative
Let do be object distance=10m
And di= image distance=-300m
Using lens formula
F=do*di/do-di= 10*300/10-300=-10.3m
Answer:
Angular acceleration is defined as the rate of change of angular velocity of a body.
consider the attached figure as shown
It rotates with an angular velocity
An point inside the object rotates along the path as indicated thus turning by an angle
in time 't'
Thus we have

physically angular acceleration can be understood as the rate at which the angular speed of any object is changing with time.
Acceleration represents the change in velocity.
