A 100 kg wooden crate rests on a wooden ramp with an 20 degrees angle of inclination. Please find x and y component of its gravitational force. Assume the Earth"s gravity 10 m/s2 round your answers to the nearest whole number, do not forget about unit and leave one space between your answers

Natural forces that can alter ecosystems include seasons and climate changes. t or f

Which process is represented by the pv diagram? a. the isobaric process b. the isovolumetric process c. the isothermal process d. the adiabatic process

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.
