The amount of work done by the person is equal to 120 Joules.
<u>Given the following data:</u>
- Displacement = 15 meters.
To calculate the amount of work done by the person at a total height of 2 meters:
<h3>How to calculate work done.</h3>
In Science, work done is calculated by multiplying force and the displacement experienced by an object.
Mathematically, work done is given by the formula:
Substituting the given parameters into the formula, we have;
Work done = 120 Joules.

Answer: 5.5 mass
Explanation: The force of gravity pulling the car up the hill = 5.5
Answer:
One atom will give electrons to another atom to fill its shell, this is an ionic bond. The atom giving away electrons becomes positive and the one recieving electrons becomes negative.
Explanation:
A wave travelling with high frequency has short wavelength and high pitched !
The concept related to solving the problem is called Standing Waves: This property relates to how, through a chain that is fixed at both ends, it has a fundamental frequency that relates the wavelength of a standing wave to the length of rope.
In other words, if we take a wave that travels in a direction on the rope from one direction, it will immediately tend to return but in the opposite direction. When having two waves traveling in the opposite direction, it is necessary to take into account that during the vibration two reflections are generated on each side. This concept sometimes called constructive interference results in a wave reflection of the type,
Where n is a positive integer,
λ is the wavelength
L is the length of the chain.
In this way it is possible to appreciate that <em>the length of the string is equal to half of a wavelength.</em>
