D I believe but I’m not so sure
Answer:
D)
Explanation:
I honestly don't like this question. It's a really poor question. But anyway, here's the explanation:
1) All search results are <em>somewhat </em>relevant. They have the keyword "cell phone" in every result. So none should be considered off-topic.
2) Matching personal opinion with given answer choices.
My personal list if any, would have been 3, 1, 2, 4.
But since the author has helped as out, 3 and 2 are guaranteed to be the top choices, the last part is determining whether search result 4 is more relevant compared to 2.
Since I believe 1 is somewhat relevant, A and C are negated. Leaving, B and D. In this situation, I would prefer 1 than 4 since search result 4 doesn't exactly help your research paper compared to search result 1. Therefore, the only choice is D.
Answer:
B) it is illegal in the United States
Explanation:
The Australian ballot is another name for a "secret ballot." Since people have traditionally liked to keep their political business to themselves, this type of voting is NOT illegal in the U.S.
To solve your problem, we can apply Newton's second law of motion.
Fⁿ = ma
<span>Fnet = net force acting on the skier </span>
<span>m = mass of the skier = 53 kg </span>
<span>a = acceleration up the slope </span>
<span>Since velocity is constant then acceleration is zero, hence the above equation becomes </span>
<span>Fnet = 0 </span>
<span>Fnet = F - Wx - f </span>
<span>where </span>
<span>F = force exerted by the tow bar </span>
<span>Wx = component of skier's weight parallel to the incline = 53(9.8)(sin 20) </span>
<span>f = frictional force = 0.160(53)(9.8)(cos 20) </span>
<span>Substituting appropriate values, </span>
<span>F - 53(9.8)(sin 20) - 0.160(53)(9.8)(cos 20) = 0 </span>
<span>and solving for F, </span>
<span>F = 99.55 N </span>
<span>Hope this helps and have a nice day!</span>
