a) How much energy is transferred to heat & sound during the bounce? 29.4 J is transferred to heat and sound b) Explain why this ball cannot bounce to a height of 12-m if it is dropped. The total energy in a system does not change according to the law of conservation of energy so it started with 98 J, it should end with 98J,bouncing to 12 m implies more than 98 J.
c) For the pendulum in “b”, what will its kinetic energy be if it loses 2-J to heat? 6) A 1-kg ball is 10-m above a table when it is dropped. It bounces to a height of 7-m. a) How much energy is transferred to heat & sound during the bounce? b) Explain why this ball cannot bounce to a height of 12-m if it is dropped.
Nov 09, 2018 · c) For a non-ideal pendulum that starts with 15 J of potential energy at the top of its swing what will its potential energy be at the top of its next swing if it loses 2-J to heat ? 6) A non-ideal 1-kg ball is 10-m above a table when it is dropped. It bounces to a height of 7-m. a) How much energy is transferred to heat & sound during the bounce?

At high school Corey Hewitt was an artist – he even had a local reputation for his mural painting. So when he took a physicsclass in Year 12 he was surprised at how much he was drawn to such a challenging subject.
If you have energy, you can do things – you can run or jump, dance or scream, ride a skateboard or swim across a river. And maybe,lying in bed on a Sunday morning, you've felt as though you don't have the energy to do anything at all.
As the world's energy demands increase, so does the pressure to use energy supplies wisely and make machines more efficient. The "star ratings" for appliances such as fridges and washing machines are one response.
The kinetic energy from the blowing air is captured by the pinwheel and transformed into mechanical energy as the pinwheel spins. The kinetic energy from the blowing air is captured by the pinwheel and transformed into electrical energy as the pinwheel spins.
answer choices. the total energy of an object due to its kinetic energy (motion) or due to its potential energy (position) is a measurement for the amount of energy.
Select the correct definition for mass. answer choices. any factor, trait, or condition that can exist in differing amounts or types. the increase in one variable is the exact same as the increase in another variable. a measure of how fast something moves in a particular direction. the force of gravity on the object.
In Greek mythology, there was a king named Sisyphus, who was a liar and a cheat. In his arrogance, Sisyphus defied the king of the gods, Zeus. Furious, Zeus decided to punish Sisyphus by forcing him to roll an immense boulder up a steep hill, only to watch in vain as it rolled back down again.
