Answer:
plz mark me as brainlst
Explanation:
The expression of the weight of the bar is given by,
W=mg
Here, g is the acceleration due to gravity
Substitute all the values
W=(18kg)(9.81m/s2)=176.58N
The expression of the angle θ
by using free body diagram is given by,
tanθ=ACBO+OC
Substitute all the values
tanθ=(1.3m)(1.2m)+(0.75m)θ=tan−1(1.31.95)θ=33.69∘
Take moment about point O and obtain the value of tension T.
∑MO=0Tsinθ×AC+W×(AO2cosθ1)−Tcosθ×CO=0
Substitute all the values
Tsin(33.69∘)×(0.75m)+(176.58N)×(1.5m2cos60∘)−Tcos(33.69∘)×(1.3m)=0T×0.416m+66.22N⋅m−T×1.081m=0−T×0.665m+66.22N⋅m=0T=−66.22N⋅m−0.665mT=99.58N

Answer:
No, I will not give in to your temper tantrum! No, I don't believe we have received your letter yet. Well, maybe she can get a ride with someone else. Oh! You startled me! So, when would you like to eat dinner?
Explanation:
The commas(,) are employed in a sentence primarily yo mark a pause or to separate the introductory part of the sentence from the rest of the sentence while an exclamation mark(!) is used to express the emotions of excitement, surprise, or any such strong feeling or emotions. As per this definition, the given blanks are filled accordingly. Since the sentence beginning with 'oh' denotes a strong emotion of surprise, it will employ the exclamation mark(!), the other sentences just mark a pause after the introductory word 'yes', 'no', or 'well' and thus, they will use comma(,).
