The fish shown above is the anglerfish. The stalk in front of its eyes is a flashing light that it uses to lure prey near its mouth. This is because the biome that it lives in is very dark.

I WIL A 2.00-kg object traveling east at 20.0 m/s collides with a 3.00-kg object traveling west at 10.0 m/s. After the collision, the 2.00-kg object has a velocity 5.00 m/s to the west. How much kinetic energy was lost during the collision? ...

Which statement describes a surface wave? A surface wave is a type of electromagnetic wave. A surface wave is a wave that travels through space. A surface wave is a wave that moves along the interface of two different materials, like air and water.

Resistors in parallel together contain less resistance than resistors in series together. Create an analogy to explain this phenomena and post it here.

Unlike the idealized voltmeter, a real voltmeter has a resistance that is not infinitely large. part a a voltmeter with resistance rv is connected across the terminals of a battery of emf e and internal resistance r.
