For the old car:-
By v = u + at
=>v = 0 + 10a
=>a = v/10 m/s^2
By s = ut + 1/2at^2
=>s = 0 + 1/2 x v/10 x 10 x 10 = 5v
Thus F = ma
=>F = m x v/10 = mv/10
=>P(old) = F x s = mv/10 x 5v = 1/2mv^2 ------------------------(i)
For new car:-
By v = u + at
=>6v = 0 + 10a
=>a = 3/5v
By s = ut + 1/2at^2
=>s = 0 + 1/2 x 3/5v x 10 x 10
=>s = 30v
By F = ma
=>F = m x 3/5v = 3mv/5
Thus P(new) = F x s = 3mv/5 x 30v = 18mv^2 ------------------------------(ii)
=>P(new) : P(old) = 18mv^2 : 1/2mv^2 = 36 : 1</span>

B
Explanation:
Hello!
Topic sentences usually try and introduce what is being discussed about in the essay, or the thesis statement. In this situation, destruction of beaches have nothing to do with sea turtles being old species, and while it talks about hurricanes, it's hard to speak of how much money it damaged when talking about the place where sea turtles lay eggs, and if we were to talk about beaches being home to sea turtles, they would not add such scary introduction like this.
However, sea turtles are actually risk of extinction due to climate change of rising seas, which was what the hint was, in the topic sentence. Therefore, the correct answer is B

Answer: You need to answer this about you.
Explanation: A competitive person enjoys games in which there is a clear winner, and generally doesn't like to lose. If you are competitive, you should explain the things you like to compete at, and how it makes you feel. E.g. chess, races, board games, entering competitions, and hating to lose.
If you are not competitive, you probably prefer the fun of the game, and don't mind if you don't win, or even don't enjoy competitive games at all. If this is you, you should explain what things you do that are not competitive, and how it makes you feel. Walking alone, reading books, gardening....
