The navion is a small light aeroplane of conventional layout and in a low speed level flight condition, the coefficients of the dimensionless lateral-directional stability quartic are given by 4b23c2? +d2^ + e2 = 0 where b2 20.889 c2 46.714-k d2 115.120 - 18.636k, e2 55.570 + 1.994k, and ky =- i- the lateral relative density parameter /i2= 11.937, and the dimensionless moment of inertia in yaw i0.037. the quartic factorises to e2 |( kiak2)= 0 d2 (а+ b2) show that if the fin were made too large, the aircraft would become dynamically unstable what would happen to the aircraft if a critical value were exceeded?

The ballistic pendulum was invented in 1742 by english mathematician benjamin robins. it consists of an initially stationary pendulum that moves after being struck by a bullet, and it is used to measure the original velocity of the bullet. the known variables are the bullet's mass m, the pendulum's mass m, and the height to which the block and bullet swing, determined by the length of the pendulum l and final angle θ. two principles of physics are necessary to solve for the bullet's original velocity. what are these principles? conservation of momentum and newton's third law conservation of energy and conservation of angular momentum grade summary deductions 0% potential 100% conservation of momentum and newton's second law. newton's second law and conservation of angular momentum. conservation of energy and newton's third law conservation of momentum and conservation of angular momentum. conservation of momentum and conservation of energy conservation of energy and newton's second law.

The first law of thermodynamics states that heat added to a system is neither created nor destroyed but is transformed ⇒ as it changes into other forms of energy.

Which of the following are considered noble gases? a. bromine b. neon c. argon d. chlorine
