OMG: As pointed out, Sirius Black was actually Draco's first cousin once removed - not his uncle. That being said, according to J. K. Rowling, yes, Harry Potter and Draco Malfoy are related - albeit distantly - by marriage, if not by blood. The Malfoys are related to the Weasleys through the Narcissa and her descent from the House of Black. We know that Ron and Draco are fifth cousins once removed. If Weasley is Sirius' second cousin once removed and if Sirius had had a child, that child would be the Weasley children's third-cousin, once removed.

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.
