<u>True</u><u> </u>
Explanation:
The force of gravity keeps all of the planets in orbit around the sun
He repealed federal taxes, Jefferson reduced military spending. He bought Louisiana from France. Considering only all these positive points and leaving aside the negative ones, one would say that the statement that "Jefferson's administration was the beginning of popular government in the United States." Is True!
Yeah, it's every state. Atoms need a certain quanta of energy to jump to each state of energy, and therefore change state depending on how much energy is absorbed and/or released. This applies to all states of matter.
Answer:
101.54m/h
Explanation:
Given that the buses are 5mi apart, and that they are both driving at the same speed of 55m/h, rate of change of distance can be determined using differentiation as;
Let l be the be the distance further away at which they will meet from the current points;
#The speed toward each other.
![\frac{dh}{dt}=0, \ \ \ \ h=constant\\\\h^2+l^2=b^2\\\\2h\frac{dh}{dt}+2l\frac{dl}{dt}=2b\frac{db}{dt}\\\\2\times5\times0+2\times12\times(-110)=2\times13\frac{db}{dt}\\\\\frac{db}{dt}=-101.54m/h](https://tex.z-dn.net/?f=%5Cfrac%7Bdh%7D%7Bdt%7D%3D0%2C%20%5C%20%5C%20%5C%20%5C%20h%3Dconstant%5C%5C%5C%5Ch%5E2%2Bl%5E2%3Db%5E2%5C%5C%5C%5C2h%5Cfrac%7Bdh%7D%7Bdt%7D%2B2l%5Cfrac%7Bdl%7D%7Bdt%7D%3D2b%5Cfrac%7Bdb%7D%7Bdt%7D%5C%5C%5C%5C2%5Ctimes5%5Ctimes0%2B2%5Ctimes12%5Ctimes%28-110%29%3D2%5Ctimes13%5Cfrac%7Bdb%7D%7Bdt%7D%5C%5C%5C%5C%5Cfrac%7Bdb%7D%7Bdt%7D%3D-101.54m%2Fh)
Hence, the rate at which the distance between the buses is changing when they are 13mi apart is 101.54m/h
