Andre, a physics undergraduate, enters a coffee shop that is holding a contest. Customers who guess the number of coffee beans inside of a closed, 20.0 fl oz aluminum commuter mug get a free pastry and an espresso drink. Motivated by the prospect of free food and coffee, Andre puts his finely-tuned estimation skills to work. Andre assumes that a typical coffee bean is about 1 cm long. Based on that assumption, what should Andre submit as his estimate for the number of coffee beans in the mug?

PLEASE ANSWER THE FOLLOWING USING KEYBOARD (TEXT NOT HAND WRITING) Given a certain vector of arbitrary length, why is it useful to compute the unit vector of this vector?

If only one answer is correct, would it be A or C? Or could both be correct? Please explain.

Given vector A=2i-3j and vector B = 2i -4j. If vector C = A -2*B then C equals ..

1. ANALYTICAL METHOD OF ADDING VECTORS Solve the same problem as PART 1 but this time analytically. START with the values below. DO NOT USE VALUES FROM PART 1. Suppose you first walk A = 12 m in a direction 20° west of north and then B= 20 m in a direction 40° south of west. Let the +x-axis coincide with the easterly direction and the +y-axis with the northerly direction. Note: In this problem, do not round values if you need to use them for calculations in subsequent parts. Rounding errors can propagate and can make your final answer lie outside the tolerance limit of 5% set for this problem. Keep all answers to 4 significant figures.

Can i get help with this problem

Vector v = <-4,4>. Draw the vector 1.5v and give its component form and its magnitude and dire

Please solving the following parts

Given the two vectors A = ( 5.5i - 3j) and  B = (-9i - 8j) determine the following: A. Vector C = A + B in vector notation, it's magnitude and its direction counterclockwise from the +x-axis. B. Vector D = A - B in Vector notation, it's magnitude and its direction counterclockwise from the +x-axis.

Can you answer problem 9? Can you also provide a short explanation for the answer you chose?
