There are so many examples for that in different areas, like TPT1 experiment carried out in our lab recently.Here's one link: http://www.alfa-chemistry.com/tpt1-cas-167218-46-4-item-290583.htm
the answer is 6969696969696969696969696 bum bum sduigfsduhfgszuigfzsughfhgdfu\gdf dyfgilsugf
When the entire group of forces acting on an object is balanced, the vector sum
of the forces is zero, and the effect of the group of forces on the object's motion
is identical to the effect of no force at all. The object continues in constant uniform
motion.
To state the outcome of the situation in three different ways:
-- The object's acceleration is zero.
-- The object's velocity is constant.
-- The object's speed and direction of motion don't change.
The direct answer to the question is: Nothing happens to its motion.
A memoir describes the biography that is personally written in which all life events are captured in words with his memory so it is not considered historical document because
<span> a memoir relies largely on the writer's memories
</span>because it rely on writer memory and he can also forget something
so correct option is C
hope it helps
