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:
T2 ∝ a3
Explanation: took the quick check
Answer:
Only a backward force is acting, no forward force.
Explanation:
- Once released from the initial push, in absence of friction, the shopping cart would continue moving forward at a constant speed forever.
- As it would move at a constant speed, no net force would be acting on it.
- So, if it is gradually slowing, there must be a net force producing an acceleration in a direction opposite to the movement.
- This force is the kinetic friction force, and is the only force acting on the cart in the horizontal direction.
- As any friction force, opposes to the relative movement between the cart and the horizontal floor, which means that is directed backward.
- This is consistent with the direction of the acceleration of the cart.
<span>The mass of an electron is not significant to the overall mass of the atom. (B)
It takes roughly 1,850 electrons to equal the mass of ONE proton or neutron,
but the most complex atom has only around 100 of them.</span>
