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:
The right answer is "1.369 m/s²".
Explanation:
The given values are:
Distance (s)
= 260 m
Initial speed (u)
= 26 m/s
Reaction time (t')
= 0.51 s
During reaction time, the distance travelled by locomotive will be:
⇒ 
Remained distance between locomotive and car:
⇒ 
Now,
The final velocity to avoid collection is, V = 0 m/s
From third equation of motion:
⇒ 
On putting the estimated values, we get
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
Answer:
a. A
Explanation:
Kepler's First Law says that the orbits of planets are ellipses with the sun at one focus of the ellipse. Moreover, Kepler’s Second Law says that the line joining the planet to the sun sweeps out equal areas in equal times as it moves along its orbit. Finally, Kepler’s Third Law says that the ratio of the squares of the periods for two planets is equal to the ratio of the cubes of their semi-major axes.
By these laws, the comet A will have lower orbital speed.
