Here in order to find out the distance between two planes after 3 hours can be calculated by the concept of relative velocity
here
speed of first plane is 700 mi/h at 31.3 degree
speed of second plane is 570 mi/h at 134 degree
now the relative velocity is given as
now the distance between them is given as
so the magnitude of the distance is given as
miles
so the distance between them is 2985.6 miles
To solve this problem we will apply the concepts of Boiling Point elevation and Freezing Point Depression. The mathematical expression that allows us to find the temperature range in which these phenomena occur is given by
Boiling Point Elevation
Here,
= Constant ( Different for each solvent)
m = Molality
Freezing Point Depression
Here,
Constant ( Different for each solvent)
m = Molality
According to the statement we have that
From the two previous relation we can find the ratio between them, therefore
We already know the change in the freezing point, then
The temperature difference in the boiling point is 100°C (Aqueous solution), therefore
Therefore the boiling point of an aqueous solution is
Answer:
A first-class lever: fulcrum is between input and output force; second-class lever: output force is between input force and fulcrum; third-class lever: input force is between fulcrum and output force

To begin, The Big Bang Theory has not been proven, and even so, that would only mean a small fraction to whether human would exist. Evolution is also a hopeless argument that many students are taught in school, spun on the basis of very little evidence. The only option we are left is, " Intelligent Design" or an " omnipotent. " This theory explains that the universe is created by an intelligent cause, not as an indirect process such as natural selection. Why we're here is unclear but, our purpose in life<span>
<span>is decided by us. No one tells what you are going to become and what your destiny is or whether you're going to be nothing in life. You decide everything. If your purpose in life is to be a good Christan or a Jew or to be the best singer, that is your purpose for living, it's your destiny</span></span>
