Answer:
Tension upwards
Force downward
Explanation:
Since the weight of the strut is uniform therefore it can be considered as a uniformly distributed load of 400 over a mass-less beam.
According to the given conditions one end of the strut is attached to a hinge and the other is loaded with a sign of 200 N and supported by a cable in the middle of the span of strut as shown in the schematic.
<u>Now, for the equilibrium condition:</u>
Forces are balanced:
i.e.
.....................(1)
Moment about any point is balanced:
<u>Taking moment about the hinge point:</u>
upwards
Now put this value in eq. (1)
i.e. negative sign denotes opposite direction to the presumed one.
downward
According to the information in the fragment, it can be inferred that it is an example of how scientific development has consequences on pre-established theories and new areas are created in science (option C)
<h3>What is a scientific theory?</h3>
A scientific theory is a term to refer to a set of concepts and observations that are proposed as principles to explain a class of phenomena.
According to the above, the discovery of germs and their relationship with human diseases was an event that changed scientific theories about human diseases because it demonstrated a different explanation than what was believed up to that time.
So, the correct answer is option C because this event changed scientific theory and opened new fields for scientific study and research.

Answer:
The height is 80 meters.
Explanation:
The equation for the distance in the second segment of the fall is as below. In it, we use the initial velocity v1 that the ball had after completing the first segment. From this equation, v1 can be determined:
Next, we use the kinematic equation for velocity at the end of the first segment of a free fall, to determine h1:
The total height is then
