Human use of land has negative impacts. Human activities contribute to the erosion and pollution of beaches. Deforestation of land can also lead to desertification and a loss of biodiversity.
Answer:
I think it's A because effusion is a gas escaping from a tiny hole
Explanation:
I just finished the test and got it right :)
Answer:
Waves; wavelength; electromagnetic energy; ultraviolet light.
Explanation:
Sound are mechanical waves that are highly dependent on matter for their propagation and transmission.
Sound travels faster through solids than it does through either liquids or gases.
Lightwave can be defined as an electromagnetic wave that does not require a medium of propagation for it to travel through a vacuum of space where no particles exist.
Hence, sound and light are both found as waves, with a variety of wavelengths. The sun, a source of light waves specifically, releases a type of electromagnetic energy. It can be found as UVA or UVB types. These lights give off different levels of ultraviolet light, some of which can be harmful.
Additionally, the ultraviolet spectrum is divided into three categories and these are; UVA, UVB ,and UVC.
Fills volume of the container.
Why? Because the gas particles have a very weak force of attraction so they move very freely and so they always fill the volume of containers.
<span>The total molecular dipole moment of a molecule is in general the vector sum of various local electric dipoles that exist in the molecule. These local electric dipoles are of two types that we will call bond dipoles and lone pair dipoles. A bond between two atoms, X and Y, in which the bond pair is unequally shared is called a polar bond.</span>
