A coin falling through a vacuum loses no energy to friction, and yet after it hits the ground it has lost all its potential and kinetic energy. Which statement best explains why the law of conservation of energy is still valid in this case?
A.) When the coin hits the ground, the ground gains potential energy that quickly changes to thermal energy.
B.) When the coin hits the ground, the ground gains kinetic energy that quickly changes to thermal energy.
C.) When the coin hits the ground, the ground gains thermal energy that quickly changes to kinetic energy.
D.) When the coin hits the ground, the ground gains thermal energy that quickly changes to potential energy.

1. A piece of rock is thrown into a pile of sand. How is energy conserved in this case? a Kinetic energy at the maximum height is converted to potential energy and when it touches the ground, it changes partially to work and heat. b. Potential energy at the maximum height is converted to translational kinetic energy and when it touches the ground, it is lost. c. Potential energy at the maximum height is converted to translational kinetic energy and...

In 2014, Damian Walters demonstrated that he could run through a vertical loop (after a lot of failed attempts). What minimum running speed did he need to do it? Assume the loop has a radius of 1.96 m, that Damian's mass is 76.5 kg, that he stays in contact with the loop at all times, and (unrealistically) that you can neglect friction and drag forces. Also, keep in mind that it's Damian's center of mass that matters, which is approximately...
Q.2 Imagine a bungee jumper stepping out of a platform initially with kinetic zero energy. Let us take the system to be the bungee jumper, the bungee cord and the Earth and let us assume that the thermal energy of the system do not change during the jump. MODEL: We can treat the bungee jumper as a particle. The bungee cord is a perfect spring of zero mass, spring constant k and position at rest ye. The system is taken...

We conducted a comprehensive literature search on drones in conservation up to October 2nd 2018, in line with related studies [10,11,35]. All searches were done by the same person in English, mainly using Google Scholar. This was further complemented through reference harvesting, citation tracking, abstracts in conference programs, and author search, using Research Gate and Mendeley (see PRISMA Flowchart in Supplementary Figure S1 Checklist and list of studies reviewed in Table S1). We then removed duplicate and unrelated results. Finally,...
Can you answer only question 5and 6 Questions: 1. How could the promotion of UK Hoover have been better designed? Be as specific as you can. 2. Given the fiasco that did occur, how do you think Maytag should have responded? 3. Comment on the following statement: “Firing the three top executives of UK Hoover is unconscionable. It smacks of a vendetta against European managers by an American parent. After all, their only ‘crime’ was a promotion that was too...
