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.
Answer:
a. exhibits retrograde motion.
Explanation:
When earth catches up to a slower moving outer planets like for example Saturn and jupitar they seems to show the retrograde motion which is actually an illusion but there exits the real retrograde motion too in some cases. In retrograde motion planets appears to move in the backward direction like from east to west rather then from west to east in the sky.
The constant force applied to the rope is 7.72 N.
<h3>Net torque on the drum</h3>
The net torque on the drum is calculated as follows;
Linear speed, v = ωr = 23 x 0.4 = 9.2 m/s
distance traveled = 14 m
<h3>Tangential acceleration</h3>
The acceleration of the drum is calculated as follows;
v² = u² + 2as
v² = 0 + 2as
v² = 2as
a = v²/2s
a = (9.2)/2(14)
a = 0.329 m/s²
<h3>Angular acceleration of the drum</h3>
<h3>Applied force</h3>
The constant force applied to the rope is calculated as follows;
