HELP! Starting from rest, Natalie and Emily are snowboarding down a hill as shown. Natalie rides the
snowboard down the shallow side and Emily rides the snowboard down the steep side.
Assume this is a frictionless situation. Also assume that Natalie and Emily are identical in
terms of size and weight. For each, the system is defined as the snowboarder, the hill, and
the earth's field.

The ratio of lift to drag l/d for a wing or airfoil is an important aerodynamic parameter, indeed, it is a direct measure of the aerodynamic efficiency of the wing. if a wing is pitched through a range of angle of attack, l/d first increases, then goes through a maximum, and then decreases. consider an infinite wing with an naca 2412 airfoil. estimate the maximum value of l/d. assume that the reynolds number is 9x10^6.

The necleus of an atom is made up of what subatomic particles?

Give me a example of a decomposer. explain what would happen if decomposers were absent from a forest ecosystem
