Answer:
Annuals: Annual ornamentals are planted each season. Flowering annuals are prominent in the landscape in favorable seasons, providing most of the color. ... Biennials: Biennial ornamentals are vegetative in their first year of growth and bloom in the next season. Examples are foxglove (Digitalis spp.)Humidity is the concentration of water vapor present in the air. Water vapor, the gaseous state of water, is generally invisible to the human eye. Humidity indicates the likelihood for precipitation, dew, or fog to be present. Humidity depends on the temperature and pressure of the system of interest.
Static friction magnitude is directly proportional to the normal force magnitude and the roughness between the sliding surfaces. The coefficient of friction is the ratio of the magnitude of frictional force divided by the normal force magnitude.
