Answer:
37.68
Step-by-step explanation:
C=2r
C=2*6*3.14
C=12*3.14
C=37.68
<h2>T
he small mass should be placed at x = 11.72 cm or x = 68.28 cm </h2>
Step-by-step explanation:
Let the small mass be m and position on x axis be y.
A 20 kg sphere is at the origin.
Distance to 20 kg mass = y
A 10 kg sphere is at x = 20 cm
Distance to 10 kg sphere = 20 - y
We have forces between them are equal
We have gravitational force
Where G = 6.67 x 10⁻¹¹ N m²/kg²
M = Mass of body 1
M = Mass of body 2
r = Distance between them
Here we have
So the small mass should be placed at x = 11.72 cm or x = 68.28 cm
Solve <span> 4x+3y+36 </span><span> = 0 </span>
<span>Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written </span>y=mx+b<span> ("y=mx+c" in the UK). </span>
"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.
<span>In this formula :
</span><span>y </span>tells us how far up the line goes
<span>x </span>tells us how far along
<span>m </span>is the Slope or Gradient i.e. how steep the line is
<span>b </span>is the Y-intercept i.e. where the line crosses the Y axis
The X and Y intercepts and the Slope are called the<span> line properties.</span><span> We shall now graph the line </span><span> 4x+3y+36 = 0</span><span> and calculate its properties</span>
