Experiments powersciencelike gasoline powers a car. If you have a theory about how the world works, it's a basic rule of science that you need to test it with an experiment. If your experiment confirms the theor
Give an example of a class 1 lever where the mechanical advantage is less than 1. How can you use mechanical advantage and velocity ratio to determine the efficiency of a lever? What do you understand by the conservation of mechanical energy? State one condition under which mechanical ener...
A way using the reformulation of the energy conservation equation in terms of heat flux to explain the thermal boundary effects on laminar convective heat transfer through a square duct is presented. For a laminar convection through a square duct, it explains that on the wall surface, the ...
If you keep pumping heat energy into the bottom of a kettle (faster than heat is escaping through the top and the sides), sooner or later the water inside it will boil. A basic law of physics called the conservation of energy tells us that if you need to boil a liter of water, ...
The conservation of energy of simple machines clearly states that the work done by the machines doesn't change and remains as the initial value of the...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question...
Energy comes in many forms: mechanical, electrical , magnetic, solar, Conservation of Energy What are potential and kinetic energy? Unit 6 Forms of Energy (6.2). WHAT IS ENERGY?. WHAT IS ENERGY? What is energy? Energy is defined as the ability to do work It is measured in joules...
For example, in extremely hot and dry environments, desert mammals exhibit physiological mechanisms that optimize water conservation (Donald & Pannabecker, 2015), nocturnal habits and a fossorial lifestyle to avoid heat stress (Schmidt-Nielsen & Schmidt-Nielsen, 1952; Walsberg, 2000), and cranial...
water sources and provides conservation, water pollution control, and more to be conducted by the Army Corps of Engineers. Some of these efforts include maintaining inland waterways, deepening nationally significant ports, upgrading dams and irrigation systems, increasing water storage infrastructure, and...
This law is called the conservation of angular momentum. When a figure skater puts their arms out, some of their mass is further from the center of their body (the point of rotation) so they have a higher moment of inertia. If they're spinning quickly with their arms out but then ...
Unfortunately, such amazing things arestrictlyprohibited by a law of physics called theconservation of energy, which says you must always put in as much energy as you get out. So let's think about pulleys in terms of energy. If you raise a weight of 100kg (1000 newtons) a distance of...
