<u>TRANSISTOR:</u>
The future of transistors based on the ongoing researches suggests that, it would be based on nano technology. This technology is itself still under development and the case is similar in the case of transistors too.
Transistors due to their applications, especially its application as an amplifier has increased its usage and the dependability over them. The hard part often arises with the fabrication techniques which are being tested and developed as we speak in order to increase the efficiency of the transistors and also to reduce their physical size though, these would mean that, the design complications would be higher.
Answer:
the location of 160 N from end E is 25mm
Explanation:
given:
A uniform plank of weight 100 N is 2000 mm long
and rests on a support that is 400 mm from end E
find:
At what distance from E must a 160 N weight be placed in order to balance the plank?
160 N
|---x--->|
100N \|/
======================||======================E
Δ---- 400mm---->|
|<---------------------------- 2000mm --------------------------->|
to determine the location of 160N load in order to balance the plank,
you have to take moment at support Δ.
note:
the 100 N is located at the center of a plank.
the distance of 100N from support = (2000 / 2) - 400 = 600mm
∑moment at Δ = 0
0 = -100 N (600mm) + 160 N (400-x)
0 = -60000 N.mm + 64000 N.mm - 160x N.mm
0 = 4000 - 160x
160x = 4000
x = 4000/160
x = 25 mm
therefore,
the location of 160 N from end E is 25mm
A plane figure with at least three straight sides and angles, and typically five or more.Polygon-
Consecutive vertices-The endpoints of one side of a polygon.
diagonal of a polygon
A polygon with all the angles equal and all the sides equal.
regular polygon
Any closed figure bounded by three or more segments that only intersect at their endpoints. The segments are called the sides, and the endpoints are called the vertices of the polygon.

Hope this helps!
Answer: X+Y=63.
Explanation:
Let X represent tomatoes
Let Y represent radishes
Area covered by tomatoes plant is 35 acres
Area covered by radishes is 28 acres.
Therefore, X = 35
Y = 28
The sum of the two area =35+28
X + Y = 35+28 = 63
