One study compared the sap and syrup from the sugar maple with those of the red maple, as well as those of the Acer saccharinum (silver maple), Acer negundo (boxelder), and Acer platanoides (Norway maple), and all were found to be equal in sweetness, flavor, and quality. However, the buds of red maple and other soft maples emerge much earlier ...
In the above system resonance happens when ω is approximately = /, i.e., is the natural (resonant) frequency of the system. The actual vibration analysis of a more complicated mechanical system — such as an airplane, a building or a bridge — is based on the linearization of the equation of motion for the system, which is a multidimensional ...
The leaves are evergreen, awl-shaped, 3–6 mm (1 ⁄ 8 – 1 ⁄ 4 in) long, and arranged spirally on the shoots. Mature cones and seed. The giant sequoia regenerates by seed. The seed cones are 4–7 cm (1 + 1 ⁄ 2 –3 in) long and mature in 18–20 months, though they typically remain green and closed for as long as 20 years. Each cone has ...
