I am really interested in becoming a pharmacist when I grow up. I plan to take the sat 2 chem and physics, but do I need to take the sat 2 bio (or even physics)? Also, what is the best pharmacy college in the north east. I heard it was Rutgers pharmacy. Is that true?

So essentially what you are saying is that acceleration can fall under the terms deceleration and if an object traveling at 40m/s has an "acceleration" of -1m/s^2, the so called "the acceleration is negative" would actually make the -1m/s^2 a positive value and therefore would be wrong? So...

but if an object is accelerating in the negative direction, then deceleration would make the acceleration negative. If something was accelerating at -9.8m/s^2, deceleration would mean the negative of the acceleration so it would go in the positive direction. So isn't that the same as the...

the answer is obviously C. But I was wonder what is so wrong with answer B.

yes, though the difficulty stated in the title was simply to attract competent physics people.

Which one of the following is true for a deceleration? a)the velocity remains constant b)the acceleration is negative C)the acceleration is in the direction opposite to the velocity d)the acceleration is zero

btw i was sick yesterday so i wasn't thinking clearly. I basically answered the question in my first response. The answer is C. I basically said that avg velocity is always less than or equal to avg speed. So avg speed is always equal to or greater than avg velocity. My bad guys...

i'm sorry, but you are doing a really bad job at answer the questions that I ask. once again, when it says "magnitude" does magnitude mean it is always positive? Velocity shows magnitude and direction. The question states the magnitude of velocity. Therefore velocity cannot show direction and...

velocity. When it says magnitude of vector, that means it needs to be positive right? Btw, I am learning physics by myself. So even if you give me more information than necessary, don't worry, you are not committing any academic integrity issues.

an arrow that represents magnitude and direction

what is the answer

umm what??!?

What can be said about average speed relative to the magnitude of the average velocity? a) greater than B) equal to C)both a and B I think it is neither because average velocity is displacement/total time and average speed is distance/total time. Since displacement is always equal to or...
