When plane is flying in tail wind condition we will have
Now during return journey we can say its would be head wind now
time = 2 + 1 = 2 hours
now add two equations
distance = 360 miles
now from above equation again
To solve this problem we will also apply the concept related to the conservation of the mass, which announces that: "In an isolated system, during any ordinary chemical reaction, the total mass in the system remains constant, that is, the mass consumed by the reagents is equal to the mass of the products obtained. "
If the mass is in a closed system, it cannot change. This assessment should not be confused with the transformation of the matter within it, for which it is possible that over time the matter will change from one form to another. For example during a chemical reaction, there is a rupture of links to reorganize into another, but said mass in the closed system is maintained.
The correct answer is:
C. "The mass of a closed system cannot change over time; mass cannot be created or destroyed."
Absolute dating and relative dating are both used commonly to determine the age of fossils. Absolute dating gives the exact date and chronological order to which the fossil lived. They do this by looking at the surrounding ground and using the carbon to find out how old it is. Relative dating is pretty similar to this except it uses carbon dating which is a way of finding the approximate age of the fossil. They do this by looking at the layers of the earth and making an assumption as to how old it is.
As heat enters the surface of the Earth the gas traps it and is not radiated it's absorbed.
