Two particles are executing simple harmonic motion with same amplitude and frequency about the same equilibrium position. they pass each other moving in opposite direction, each time their displacement is half their amplitude. what is the difference between their phase constants?

Carbon 14 is a naturally occurring stable

This is a form of winter precipitation. it is frozen precipitation falling as ice pellets. snowflakes melt into raindrops as they pass through a thin layer of warmer air. the raindrops then refreeze into particles of ice when they fall into a layer of sub-freezing air near the surface of the earth. this precipitation is called a) hail. b) rain. c) sleet. d) snow.

You can melt ice by applying pressure because the solid/liquid line has a slope.
