Plz link the options to the numbers plz. options: exothermic conservation of energy pendulum bob chemical energy period potential energy endothermic kinetic energy nuclear energy 1. when wood or paper is burned, chemical energy is changed into thermal energy. this is an example of an process. 2. when a plant absorbs sunlight and does photosynthesis, electromagnetic energy is converted into chemical energy stored in the plant’s tissues. this is an example of an process. 3. a device with a weight swinging at the end of a string or rod which is only affected by gravity is called a 4. the weight at the end of the pendulum string is called a 5. the amount of time for a recurring event to take place is called a in a pendulum this is the amount of time for the bob to completely swing back and forth one time. 6. a fundamental belief in science is that energy cannot be created or destroyed. it can only change forms. this is called 7. when a child swinging on a swing set is it at the highest point of a swing, the is at a maximum because the height is at the maximum. 8. when a child swinging on a swing set is at the lowest point of the swing, the is at a maximum because the velocity is at the maximum. 9. can be stored in chemical bonds and released as heat during chemical reactions. 10. the sunlight released by the sun is an example of being converted to electromagnetic energy.

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.
