Aheavy stone of mass m is hung from the ceiling by a thin 8.25-g wire that is 65.0 cm long. when you gently pluck the upper end of the wire, a pulse travels down the wire and returns 7.84 ms later, having reflected off the lower end. the stone is heavy enough to prevent the lower end of the wire from moving. what is the mass m of the stone?

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

happy to

pls mark as brainliest.

hope this .!

that would be because of both gravity and friction. so     c
