What do velocity and acceleration have in common?

Wavelength divides in half and speed stays the same.

The particles of the gas inside the ball heats up, bouncing off each other and spreading farther apart.hope my answer has you : )

It was crowded with sewer like smells. bad sewer systems

I'm having some difficulty seeing the diagram clearly.but the question says there's a net inward force on the object.so we know right away,  from newton's 2nd law of motion, thatthat baby is accelerating.  it doesn't even matter which way thenet force is pointing.  if there's any net force, then either theobject's speed or else its direction must be changing.
