A particle executes simple harmonic motion with an amplitude of 2.18 cm.
At what positive displacement from the midpoint of its motion does its speed equal one half of its maximum speed?
Answer in units of cm.

The positive displacement from the midpoint of its motion at the speed equal one half of its maximum speed is 3.56 cm.

Explanation:

Maximum speed is  :

                          v (max) = Aω

Speed v at any displacement y is given by  

= ( - )   ........................................................  i

And,

               v = v (max)  

          or,  2 × v = Aω     ....................................................   ii

Eliminating  ω from equations i and ii,

                           =    (  - )

                     or, =  ()  =()

                    or,  y =  3.56 cm.

when cloud cover increases then the suns ray's which provides the earth with light and warmth gets covered due to the due to the suns ray's being blocked, the temperature in that region

therefore to conclude i would like to say that,

=more the cloud cover, the lesser the

pls mark as brainliest.

a.) travels faster in solids because the particles are closer together.

air is a gas water is a liquid
