Answer:
which two statements describe how soil horizons are formed?
Explanation:
A soil horizon is a layer parallel to the soil surface whose physical, chemical and biological characteristics differ from the layers above and beneath. Horizons are defined in many cases by obvious physical features, mainly colour and texture.
Answer:
Velocity of the wave is 1.7 m/s
Explanation:
As we know that the frequency of the wave is defined as the number of waves crossing a fixed point per second
So here we will have
Also we know that the distance between two consecutive crest or two consecutive trough is known as wavelength
So here the wavelength of the wave is given as
now we have
Answer: 1- Issac Newton is the man who discovered gravity. he is important because he found out why everyone was pulled down to the ground. this would later hepl disprove the flat earth theory.
2- Id on't know the vocab words. do those. it'll be the quickest.
3- wieght is how much is being pulled to the ground. mass is how big you are. A pound of rocks and a pound of feathers wiegh the same, but the mass of a pound of feathers will be much greather, as it takes much more feathers to equal a poud than rocks.
Explanation: CHEACK ALL SPELLING!!!! I can't spell that well and my g key doenst like working.
An object with volume greater than it mass. to account less density and thus it will float
All you need to do is count the number of Oxygen the Products:
In 6H2O, you have 6 oxygen, and in 6CO2, you have 6 Dioxygen so 12 Oxygen. So a total of 12 + 6 = 18 atoms of Oxygen, or 9 atoms of dioxygen.
So the coefficient that should be placed in front of O2 to balance the reaction is 9:
C6H12 + 9O2 ---> 6H2O + 6CO2
Hope this Helps! :)
