Work Done = force x displacement. So in this case the 15N is the force (because weight is a force) and 0.60m is the displacement. Therefore 15 x 0.6 = 9 Joules of work done (btw, work done can also be referred to as energy transferred)
Answer:
Increases
Explanation:
Atomic size is the amount of space between the nucleus of an atom and the outermost electron. So, as each additional energy level is added, the overall amount of space between the nucleus and the outermost electron increases because there is now an extra shell of electrons that is farther out.
To calculate the mass percentage of any chemical element in a given compound, we will divide the mass of the element in 1 mole of the compound by the compound's molar mass and multiply the result by 100
<h3>What is an element?</h3>
An element is a substance which cannot be split into simpler forms by an ordinary chemical process. This simply goes to say that elements are substances which cannot be decomposed into simpler substances by ordinary chemical reactions.
An atom is the smallest unit or part of an element which can take part in a chemical reaction.
On a general note, elements are classified as thus:
- Metals, non-metal, and metalloid.
- The extreme left side elements in the periodic table are metals, for example, aluminum, sodium, calcium, caesium, etc.
- However, elements on the right side are generally referred to as non-metals, carbon, chlorine, oxygen,
So therefore, to calculate the mass percentage of any chemical element in a given compound, we will divide the mass of the element in 1 mole of the compound by the compound's molar mass and multiply the result by 100

Superfluidity is the characteristic property of a fluid with zero viscosity which therefore flows without loss of kinetic energy. An example of a superfluid would be liquid helium.
