Mathematics: Post your doubts here!
This is, in essence, an incorrect question to begin with (I think). The distance of a point from a line is never constant. What can be asked is the distance of a point from another point on a line. You're probably missing some essential detail of the question. I could be wrong, but I'm pretty... -
Equivalence.
What are they showing at the end? What does this imply: 990/1100 ? -

^I'd rather fail than listen to that BS. My ears are bleeding from the mispronunciations. -
Mathematics: Post your doubts here!
Would you know if the answers in the book are normally reliable? Because I used two ways to find the answer and both ways gave me the same answer. The first way is obviously using chain rule. The second way is by the following formula: Rate of flow of liquid = velocity at which liquid is... -

Think about it... how else could they have been connected? There are clearly spaces between the individual wires. This shows that they are infact 7 distinct wires running alongside each other. The only way they could have been in series would be if they were connected end to end. (PS: Real... -

Question 8 was already answered above. Question 15: F = ma1 1/2 m u^2 = 4 1/2 m v^2 = 8 That leaves us with a1 = F/m u^2 = 8/m v^2 = 16/m We put these in the formula: v^2 = u^2 + 2a(1)s That gives us: 16/m = 8/m + 2(F/m)s 8/m = (2Fs)/m Fs = 4 ---------- Now, in the next part 2F = ma2... -

- Question 11 Driving force = m x a = 2 x 9.81 = 19.62 Driving force - frictional force = m x a 19.62 - 6 = (8+2) x a a = 1.362. Approximately = 1.4 m/s^2 Now the main doubt here is why are we doing 8+2. It would help if you've studied P4 mathematics, but if you haven't, then this is why: T =... -

That's what I am getting too: 1.194 cm/s. What book is this question in? The answer may be wrong. -
