a wave is represented by the equation y=2sinx (0.5x-700t) where all distances are measured in centimeter and time in seconds. for this wave calculate it. (1) frequency (2)wavelength (3)speed

What is the force that opposes motion and works against the downward pull? a) friction b) gravity c) weight d) acceleration

Why is rain likely when warm, moisture-laden air meets cold air? a) the lighter warm air will rise and cool down, causing condensation and rain. b) the cold air moves faster and pushes the warm air away, causing condensation and rain. c) the moisture in the warm air condenses on contact with the cold air, causing rain to fall. d) the cold air mixes with the warm air, reducing its temperature causing moisture to condense.

Often called simply "velocity," this is the velocity of an object at a particular moment in time.
