Please check.
1. Which of the following quantities are scalars, and which are vectors?
a. the acceleration of a plane as it takes off VECTOR
b. the number of passengers on the plane SCALAR
c. the duration of the flight SCALAR
d. the displacement of the flight VECTOR
e. the amount of fuel required for the flight SCALAR
The only one I might question is d. If by 'displacement' the question means distance, then it's a scalar. If it means directed distance then it's a vector. I'm not entirely sure how the word is being used, so check your text for any clarification it might give for that word. The others look correct to me.
i need help with my homework it is about vectors and their is no good sites to help me with them what should i do and it has to be in for tommorow :S
