1 answer:
Answer: 2 diodes
Explanation:
Given : In proof testing of circuit boards, the probability that any particular diode will fail is 0.01.
The number of diodes contained by circuit board = 200
Then , the expected number of diodes to fail is given by :-
Therefore, there are 2 diodes that we will expect to fail.

Answer:
The magnitude of the resultant force is
The direction of the resultant force is from the horizontal plane
Explanation:
Generally when resolving force, if the force (F )is moving toward the angle then the resolve force will be while if the force is moving away from the angle then the resolved force is
Now from the diagram let resolve the forces to their horizontal component
So
Now resolving these force into their vertical component can be mathematically evaluated as
Now the resultant force is mathematically evaluated as
substituting values
The direction of the resultant force is evaluated as
substituting values
from the horizontal plane
