To, find the energy that the first wave carries. This is given by:
2(A^2),
where A is the amplitude of the function. Your first wave is:
2(0.5)^2 = 2(.25) = 0.5,
so its energy is 1/2. Compare that to the energy of A=1 m:
2(1)^2 = 2(1) = 2
The energy increased by a factor of 2^2 (that is, 4), so we take the difference:
dE = E[final] - E[initial]
dE = 2 - 0.5 = 1.5
Energy of the 2nd wave (probably sinusoidal as a guess) is greater by 1.5 J.

How does a waves energy affect its amplitude?
How is the energy of the wave affected if the amplitude of the wave increases form 2 meters to 4 meters
How is an amplitude measured?
Assuming peak-to-peak amplitude, it can be measured by simply using meters (also spelled metres, depending on where you are from).
How can amplitude be measured?
It can be measured from zero to the highest value vertically.This can be done with specific meters depending what you are measuring
What types of meters are used in Energy Management Systems?
Energy Management Systems use many different types of meters. Energy Management Systems install and supply gas meters, water meters, and electric meters.
Mary weighs 533 Nand she walks down a flight of stairs 4m below her starting point what is the change in marys potential energy?
That's a mighty heavy woman! Anyway, potential energy is calculated as mgh, that is, mass x gravity x height. To calculate in SI units, mass should be in kilograms, gravity is about 9.8 meters per second square, and height in meters. Since she goes down, the change in potential energy is negative - her negative energy decreases.That's a mighty heavy woman!

What is the SI unit of the amplitude of a wave?
We need a length or distance measurement here. The unit is meter or a part of it, like centimeter, millimeter.

What is the difference between wavelenghtand amplitude?
The wavelength is the distance the wave travels before repeating in meters. The amplitude of the wave is the deflection from peak to trough in units of the wave value, e.g electric field or velocity.
As the speed of a bicycle moving along a horizontal surface increases from 2 meters per second to 4 meters per second the bicycle's gravitational potential energy?
There is no change. The bike is moving along a horizontal surface, and only a change in height can change the gravitational PE.
Two blocks with the same mass are 8 meters apart The blocks are then moved so that they are 16 meters apart How would this change the gravitational force acting between the two blocks?
It would decrease because the distance between the blocks has increased.
What is the purpose of installation BTU Meter in LPG?
BTU meters measure energy change in liquid or gas flows, it also helps to measure the total energy used or transferred in a gas system.
