Opposite rays
From the term “opposite” which is derived from the Latin word
“oppositus” meaning “set against”, Opposite Rays are two rays which start from one
common point and is pointed outwards in an exact opposite direction from each
other forming a straight line.
<span>For example, this is Line A
<<<+========== ;
this is Line B ==========+>>></span>
Line A and Line B are two rays but they can only be called
Opposite Rays when they both start from a common point which is Letter O; thus,
forming a straight line.
A <<<+========== O
==========+>>> B
When there are opposite rays, points A, O, and B are
collinear, meaning these points are present in the same straight line.
It is the red line the purple line carries the most the green line is the largest and the smallest is sky blue
I think it’s 10 kg since 20/2=10
Answer:
9.8N
Explanation:
Here we can get gravitational acceleration according to the place where object is placed by bellow equation
g = GM/R²
g - Gravitational Acceleration
G - Gravitational constant (6.67×10-11)
R - Distance ( Radius )
g = 6.67 × 10-11 × 1024 /(6.37×106)²
g = 9.8 m/s²
There for
Weight = Mass × Gravitational acceleration
= 1×9.8
= 9.8 N
Well if the rock doesn't move, then there is no amount of work done. There is no work done on an object if a force is applied to the object but it DOES NOT change its position, in this case is the rock.
