Answer:0.3
Explanation:
Given
velocity of car=15 m/s
truck brought to halt in a distance of 38 m
We know
Final velocity (v)=0
(deceleration)
Therefore minimum coefficient of friction \mu will be
Reflection occurs in many scenarios in our everyday life. Reflection occurs
when light travels in one medium and comes into contact with another.
However, what if a light wave is moving from one location to another but
the mediums stay the same, what happens to that light wave?*
it will reflect with the same amount of intensity
Composition Is the property
centripetal acceleration is given by formula
given that
now we have
so the ratationa frequency is given by
