What makes graphite soft and slippery? The delocalised electrons are free to move through the structure, so graphite can conduct electricity. The layers in graphite can slide over each other because the forces between them are weak. This makes graphite slippery, so it is useful as a lubricant . Should I use graphite or wd40 […]
What are some of the economic and physical impacts of a disaster?
What are some of the economic and physical impacts of a disaster? Natural disasters such as earthquakes, floods, typhoons, and hurricanes inflict serious damage and so seem to be bad for the economy. For firms, natural disasters destroy tangible assets such as buildings and equipment – as well as human capital – and thereby deteriorate […]
Which of the following independent variable Cannot be manipulated in a research study?
Which of the following independent variable Cannot be manipulated in a research study? The correct answer is C, a subject variable. Looking back to item #21, when we have subject variables, these are variables that participants bring into the study with them, such as their gender or political affiliation.

Why is bubble wrap not a good insulator?
Why is bubble wrap not a good insulator? Bubble wrap is an excellent insulator thanks to small pockets of air trapped within the bubbles. After applying bubble wrap insulation to your windowpane from the inside, tiny bubbles serve as a network of many insulating pockets filled with air. It is not a good thermal insulator. […]
What are three ways scientists share their findings?
What are three ways scientists share their findings? Scientists often communicate their research results in three general ways. One is to publish their results in peer-reviewed journals that can be ready by other scientists. Two is to present their results at national and international conferences where other scientists can listen to presentations. How do researchers […]

Do holes move in semiconductor?
Do holes move in semiconductor? In semiconductor holes are there. When electron jumps into the hole we see that holes are moving but holes are not moving. Electron fits into the vacant space hence from where it was came from it will create the hole over there. Hence we come to the point that holes […]
