Answer:
B). Clyde had succeeded earlier in the same competition.
Explanation:
As per the question, option B i.e. 'Clyde had succeeded earlier in the same competition' seems to be the most accurate as it appropriately that Clyde must have had the earlier experience of succeeding in the same competition because after witnessing a failure an individual requires sufficient motivational strength to regain the vigor to perform with full strength and succeed. Thus, <u>Clyde must have gained this motivation and encouragement from her successful past experience to succeed in the competition which Sarah did not have and thus, she failed.</u> Therefore, <u>option B</u> is the correct answer.
The correct answer is C because, A platform is an official statement of party policy. A plank are the specific issues that make up a platform, while a referendum when voters go to the polls to decide a specific issue, like the donut tax, for example.
The object must move with the speed of
times to approximately seeing that it is contracted to exactly half of its actual length.
<h3>How is this calculated?</h3>
The length contraction experimented by the object as it approaches lightspeed, in meters per second, is described by Lorentz contraction formula:

Here, v is the current speed m/s
c is the speed of light in m/s
L' is the length of the object at rest in m
L is the length of the object at the current speed in m
Now we know that
and
then,

Hence, r = 
Therefore, the answer is the object must travel at a speed of
times the lightspeed to be contracted to one-half its proper length.
