If y(x, t) = (5.2 mm) sin[kx + (450 rad/s)t + φ] describes a wave traveling along a string, how much time does any given point on the string take to move between displacements y = +3.4 mm and y = -3.4 mm?

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.

d. platinum would have the greatest temperature increase because it has the lowest specific heat.

it is b. absorbs thermal energy
