Turning on a light switch converts mechanical energy to electrical and radiant energy. So Mechanical energy
Answer:
Each nitrogen molecule consists of two atoms of nitrogen that are bonded by a triple covalent bond. This is because each nitrogen atom has 5 valence electrons. Each atom can complete its octet by sharing three electrons.
I hope this helps!
Answer:
Human activities and natural processes have influenced the change in the global temperature by the following processes
1) Green house gas such as carbon dioxide, methane, ozone, nitrous oxide and fluorinated gases produced by the combustion of fossil fuels the use of industrial chemicals, the production of coal, and natural gas
2) Deforestation which reduces the natural process of conversion of carbon dioxide to oxygen, thereby, increasing the greenhouse gases in the atmosphere
3) The accumulation of the greenhouse gases in the atmosphere results in the trapping of heat in the atmosphere, causing the atmospheric temperature to rise
4) Changes in the amount of energy produced by the Sun can result in an increase or decrease in the atmospheric temperature
5) Volcanic activity that occurs at a sufficiently large scale can produce sulfur dioxide that blocks the rays of the Sun from reaching the Earth, resulting in a change of atmospheric temperature.
Explanation:
Electric field due to a point charge is given by formula
now due to negative charge also the magnitude of electric field will be same
only difference is the direction of field due to negative charge is radially inwards
now we can say that net field due to these two charges is given as
now it is given that distance r is very large than "d" so we can say
<em>so above is the electric field due to dipole</em>
Answer:
one of the reasons is that it wets the glass thermometer it also doesn't detect slight changes in temperature of the atmosphere it has a high boiling point I don't know the rest
