Umm this should be in physics but F is proportional to 1/r^2 I am assuming you want to just take the derivative in respect to r of both sides of the equation
F = (2.99x10^16)/r^2
So you do that and you get
dF/dr = -2(2.99 * 10 ^16)/ (r^3)
is this for calc class?
The sum of the numbers should total to 1. Let us say that
x is the missing number, therefore:
x + ¼ + ¼ + 1/5 = 1
x = 1 – ¼ - ¼ - 1/5
The numbers should have similar denominator:
x = 20/20 – 5/20 – 5/20 – 4/20
x = 6/20
<span>x = 3/10</span>
Answer:
<h2>49.49%</h2>
Step-by-step explanation:
volume of liquid in the flask= 200 cm^3
radius of the flask = 3 cm
height of the flask= 12 cm
volume of flask is given by =
putting values and solving we get =396 cm^3
therefore the volume unfilled= 396-200= 196cm^3
therefore % of volume unfilled= 196/396*100= 49.49%
Answer:
86.6
Step-by-step explanation:

Here, AB represents height of the building, BC represents distance of the building from the point of observation.
In the right triangle ABC, the side which is opposite to the angle 60 degree is known as opposite side (AB), the side which is opposite to 90 degree is called hypotenuse side (AC) and the remaining side is called adjacent side (BC).
Now we need to find the length of the side AB.
tanθ = Opposite side/Adjacent side
tan 60° = AB/BC
√3 = AB/50
√3 x 50 = AB
AB = 50√3
Approximate value of √3 is 1.732
AB = 50 (1.732)
AB = 86.6 m
So, the height of the building is 86.6 m
