For the same wave, the product product of
(wavelength) times (frequency)
is always the same number. (It happens to be the speed of the wave.)
So if one of them changes, the other one has to change in the opposite
direction, in order to keep their product constant.
For electromagnetic waves, higher frequency means higher energy.
I'm not sure about mechanical waves just now.
To solve this problem we will proceed to use the equations given for the calculation of the resistance, in order to find the radius of the cable. Once the length is found we can find the number of turns of the solenoid and finally the net length of it
The resistance of the wire is
= Resistivity
L = Length
A = Cross-sectional Area
That can be also expressed as,
Rearranging the equation for the length of the wire we have
The number of turns of the solenoid is
Denominator is equal to the circumference of the loop
Finally the Length of he solenoid is
Where \phi is the diameter of wire
Therefore the length of the solenoid is 7.532m
Answer:
Sir Isaac Newton
Explanation:
The laws according to which bodies move and how one body attracts another body were developed by Newton. The three laws of motion and the law of universal gravitation were developed by Newton.
In the seventeenth century almost all the refracting telescopes exhibited color distortion. Newton believed that white light had a spectrum which was the reason for this distortion. The lens of a refracting telescope used to act like a prism which caused the dispersion of light proving Newton's hypothesis.
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:
Answer:
Lose or gain
Explanation:
Ions are formed when atoms lose or gain electrons in order to fulfill the octet rule and have full outer valence electron shells. When they lose electrons, they become positively charged and are named cations. When they gain electrons, they are negatively charged and are named anions.
