A light airplane uses a NACA 4415 airfoil. It has a rectangular wing planform, with an area of 15.3 m2 and a span of 10.2 m. The aircraft is flying at a gross weight of 7340 N. Neglecting any finite wing effects (induced drag) and assuming sea level conditions, at what angle of attack will the aircraft be flying when its airspeed is 160 km/h?

Wind and moving water provide energy. question 1 options: chemical mechanical thermal none of the above

Acyclotron is used to produce a beam of high-energy deuterons that then collide with a target to produce radioactive isotopes for a medical procedure. deuterons are nuclei of deuterium, an isotope of hydrogen, consisting of one neutron and one proton, with total mass 3.34×10−27kg. the deuterons exit the cyclotron with a kinetic energy of 6.40 mev .a-what is the speed of the deuterons when they exit? b-if the magnetic field inside the cyclotron is 1.25 t, what is the diameter of the deuterons' largest orbit, just before they exit? c-if the beam current is 350 μa how many deuterons strike the target each second?
