Answer:
Forces in our Universe
Step-by-step explanation:
a)
First of all we have,
and,
We need to define a function that allows us to find said change based on r, so one of the functions that shows that change is,
That is,
For this case F is a conservative field and the line integral is independent of the path. Thus, defining 
and 
. So the amount of work on the movement of the object from P1 to P2 is,
2) The gravitational force field is given by,
The maximum distance from the earth to the sun is 
km and the minimum distance is 
km. The mass values of the bodies are given by m = 
kg, M = 
kg and the constant G is 
In this way we raise the problem like this,
Answer:
First day: $75
Second day: $107
Together: $182
Step-by-step explanation:
First day:
$60 + $15 = $75
Second day:
$95 + $12 = $107
Together: $182
Answer:
y=1/2x+6
Step-by-step explanation:
Answer:
w = 9.82
x = 66.73
Step-by-step explanation:
By applying tangent rule in triangle ABD,
tan(81°) = 
6.31 = 
w = 
w = 9.82
Similarly,
tan(39°) =
0.81 = 
0.81 = 
9.82 + x = 
x = 76.56 - 9.82
x = 66.74
