    yes a is false
  72. geometry

    No because that would be three different lines connecting each point not just one straight line through them all it wouldn't work out
  73. geometry

    Its a because a line with just one point is called a ray and it starts from the point and it extends forever (so that's one point and a line)

  83. chemistry

    If I remember correctly, the higher the temperature, the density will be less. If it is warmer the molecules/particles move faster and produce more collisions. More collision and movement mean less stability for the object overall. And vice versa: cool temperature will mean ...

  85. Physics Again

    Ok, so I came up with part an answer for the question I posted, hoping that someone can compare with me. I..this is what I did.... found the displacement of car before red light, time it takes for the car to accelerate to its velocity, after the red light, the time of the car ...
  86. Grammar

    mhmh well I would say yes then, because to me it makes me think about your writing and why you write that way. Which, in my opinion is one thing that you want the marker of this narrative to catch on to. I would ask your prof. or teacher if you have a chance before handing in...
  87. Grammar

    You would have to wait for someone else to answer this, but my guess would be that the did is there to emphasize the try. As to if this allowed in essays? I'm not sure, my guess would be no, but maybe I'm wrong. In poerty this would be acceptable:)...also is this an ...

  93. Science

    Because biases sometimes leave out necessary things. A bias means the article is only one sided (most of the time). You need to pick out what sounds like it is the author's opinion, so you can decided for yourself if it is the same opinion you have. Or, if things were left...
  94. Science

    haha no problem!
  95. Science

    Science changes as technology adavnces. With new advancements comes new technology, New technology means new ideas, and with new ideas, things change. Years ago there were no such things as cancer treatments. Now, technology has changed which means new things/materials/drugs/...

  98. We don't do YOUR WORK

    I agree, I hate people who get others to do their work! Which, is why I am appologizing! I think the question I posted made it sound like I wanted you all to do it for me...I posted again by the way. But seriously, I agree! This is the first time I have ever done anything like...

    A car and train move together along parallel paths at 25 m/s [W]. The car then undergoes a uniform acceleration of 2.5m/s^2 [E] because of a red light and comes to rest. It remains at rest for 45s, then accelerates back to a velocity of 25m/s [W] at a rate of 2.5m/s^2 [W]. How...
