Why do bungee jumpers use ropes that have small values of the force constant?
Bungee jumpers use ropes that have small values of the force constant because they want maximum stretching for their cords to preserve as much energy as possible from their initial fall. The units of force constant are N/m. On a bungee cord, you would like the stretch to takes as little force as possible per meter of cord.
The maximum energy of a photon is expressed as?
The maximum energy of a photon is often expressed as Planck's Law or constant. It is also referred to as "h" and is used in quantum mechanics as well.
What is constant displacement?
In Wien's experiment it was found that when the temperature of the source increases, then the wavelength for which the radiant energy becomes maximum decreases. This displacement towards the lower wavelength side as temperature increases is termed as displacement law. So if T, the temperature of the source in kelvin and lambda m is the wavelength for which the energy is maximum. Then lambdam *T = constant. This constant is known as Wien's constant, whose value is 5.67 x 10-8 mK.
How is potential energy in a spring defined?
It can be defined as the work required to stretch or compress the string - the product of force times distance, as an integral, because the force is not constant.
What energy transformations allows you to send a rubber band flying across the room?
elastic potential energy:]The rubber band has strain energy, equal to the band 1/2 spring constant times the square of the stretch. This is converted to kinetic energy when released.

Why does streaching a rubber band increase its potential energy?
its potential energy is 1/2kx^2 -k is its spring constant and x its displacement - the higher the stretch, the more the energy which goes as the square of the stretch, x
Is the energy of carnot engine is maximum?
The work output of a Carnot engine would be the maximum possible, i.e. it would yield the maximum possible efficiency for conversion of input energy into useful work.

Gibbs quantity of maximum possible work?
Gibbs free energy represents the maximum reversible work that can be extracted from a system at constant temperature and pressure. It combines the system's enthalpy and entropy to predict whether a reaction is spontaneous. The change in Gibbs free energy (∆G) determines whether a reaction will proceed spontaneously or not.
Which energy levels holds more than 8 electrons?
Energy levels from 3 and above can have more than 8 electrons maximum. Maximum of 2n2 electrons is possible where n is the energy level.
Because of the constant loss of energy, there can be a maximum of 7trophic levels in a food chain,TRUEFALSE?
True
Is it possible for a ball to also have potential energy as it is rolling?
Yes, if it is rolling at a constant speed it has potential energy.
Can there be 20 electrons in the thrid energy level?
No. Maximum of 18 electrons is possible in third energy level.
When you stretch out a spring at what point would you have the greatest potential energy?
A spring has maximum potential energy at maximum displacement from equilibrium. This means that the greatest potential energy will occur when a spring is stretched as far as it will stretch or compressed as tightly as it will compress. In an oscillating system, where an object attached to a spring is moving back and forth at a given frequency, the object will oscillate about the equilibrium point, and the potential energy of the system will be greatest (and equal) when the object is farthest from equilibrium on either side.
