How does mechanical energy differ between a stationary car at the top of a hill and the same car rolling down the hill?
How does mechanical energy differ between a stationary car at the top of a hill and the same car rolling down the hill?
- The car at the top possesses kinetic energy, while the car rolling down converts it to potential energy.
- The car rolling down has only potential energy, while the car at the top has both potential and kinetic energy.
- Both cars possess equal amounts of mechanical energy, but in different forms.
- The car at the top possesses potential energy which is converted to kinetic energy as it rolls down. (correct)
A scientist is examining a rock sample. Which set of characteristics would classify the sample as a mineral?
A scientist is examining a rock sample. Which set of characteristics would classify the sample as a mineral?
- Man-made, metallic, consistent chemical composition, amorphous structure.
- Organic origin, variable chemical composition, amorphous structure.
- Naturally occurring, organic, variable chemical composition, crystalline structure.
- Naturally occurring, inorganic, consistent chemical composition, crystalline structure. (correct)
How does incomplete metamorphosis, as experienced by a nymph, differ from complete metamorphosis?
How does incomplete metamorphosis, as experienced by a nymph, differ from complete metamorphosis?
- Incomplete metamorphosis involves a pupal stage, while complete metamorphosis does not.
- Incomplete metamorphosis includes a larval stage, while complete metamorphosis does not.
- Incomplete metamorphosis features a nymph stage resembling a smaller adult, whereas complete metamorphosis includes a distinct larval stage. (correct)
- Incomplete metamorphosis results in offspring genetically identical to the parent, unlike complete metamorphosis.
