Plastic is what they are made of
Answer:
it is very hard question for me sorry i cant solve it
Explanation:
In the given situation two forces are working. These are:
1) Electric force (acting in the downward direction) = qE
2) weight (acting in the downward direction) = mg
Therefore, work done by all the forces = change in kinetic energy
Hence,
It is known that the weight of electron is far less compared to electric force. Therefore, we can neglect the weight and the above equation will be as follows.

v = 
= 592999 m/s
Since, the electron is travelling downwards it means that it looses the potential energy.
Abstract. Abstract is defined as an idea or plan but no actions are done
to pursue the idea. When setting goals, one must be certain and it should be attainable in order
to achieve the goal being set. Goals that are abstract
are often poorly written and uncertain
:)
My personal understanding and opinion is that ALL of those questions
should be part of an assessment of Physical Activity Readiness.
