Answer:
C = 6 pi cm or approximately 18.84 cm
Step-by-step explanation:
The circumference of a circle is given by
C = pi * d
C = 6 pi
If we approximate pi by 3.14
C = 6 * 3.14
C =18.84
The gravitational force acting between two objects is calculated by,
F = G x (m1 x m2) / d²
where G is the universal gravitational constant, m1 and m2 are the masses of the objects, and d is the distance between them. The distance between the spheres is twice the measure of the radius.
Substituting,
F = (6.674 x 10^-11) x (900 kg x 900 kg) / (0.40 m)²
Thus, the gravitational force between the spheres is approximately 3.378x10^-4 N.
Here you go I hope this helps!! :)
Answer: Its proportional, because if we increase y by for example 3, value of x will increase by 3 too.
Step-by-step explanation:
Given :
A building is of unknown height. At a distance of 400 feet away from the building .
An observer notices that the angle of elevation to the top of the building is 35º and that the angle of elevation to a poster on the side of the building is 15º .
To Find :
How far is the poster from the roof of the building .
Solution :
Height is given by :
( Here , is angle of elevation )
So , height of tower :
For height of poster :
Therefore , distance of poster from the roof of the building is :
Hence , this is the required solution .
