Ba điện trở l0KΩ-l/2watt ghép nối tiếp với nhau, giá trị điện trở Rtđ và công suất Prt của điện trở tương đương là:

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.

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

What happens to the vapor pressure of a substance when its surface area is increased at constant temperature?
