If you take two steps of different sizes, can you end up at your starting point? More generally, can two vectors with different magnitudes ever add to zero? Can three or more?
Use graphical methods to solve these problems. You may assume data taken from graphs is accurate to three digits.
Find the following for path A in
[link] : (a) the total distance traveled, and (b) the magnitude and direction of the displacement from start to finish.
Find the following for path B in
[link] : (a) the total distance traveled, and (b) the magnitude and direction of the displacement from start to finish.
Suppose you walk 18.0 m straight west and then 25.0 m straight north. How far are you from your starting point, and what is the compass direction of a line connecting your starting point to your final position? (If you represent the two legs of the walk as vector displacements
and
, as in
[link] , then this problem asks you to find their sum
.)
Suppose you first walk 12.0 m in a direction
west of north and then 20.0 m in a direction
south of west. How far are you from your starting point, and what is the compass direction of a line connecting your starting point to your final position? (If you represent the two legs of the walk as vector displacements
and
, as in
[link] , then this problem finds their sum
.)
Repeat the problem above, but reverse the order of the two legs of the walk; show that you get the same final result. That is, you first walk leg
, which is 20.0 m in a direction exactly
south of west, and then leg
, which is 12.0 m in a direction exactly
west of north. (This problem shows that
.)
(a) Repeat the problem two problems prior, but for the second leg you walk 20.0 m in a direction
north of east (which is equivalent to subtracting
from
—that is, to finding
). (b) Repeat the problem two problems prior, but now you first walk 20.0 m in a direction
south of west and then 12.0 m in a direction
east of south (which is equivalent to subtracting
from
—that is, to finding
). Show that this is the case.
Show that the
order of addition of three vectors does not affect their sum. Show this property by choosing any three vectors
,
, and
, all having different lengths and directions. Find the sum
then find their sum when added in a different order and show the result is the same. (There are five other orders in which
,
, and
can be added; choose only one.)
is it possible to leave every good at the same level
Joseph
I don't think so. because check it, if the demand for chicken increases, people will no longer consume fish like they used to causing a fall in the demand for fish

is not really possible to let the value of a goods to be same at the same time.....

Suppose the inflation rate is 6%, does it mean that all the goods you purchase will cost
6% more than previous year? Provide with reasoning.
Not necessarily. To measure the inflation rate economists normally use an averaged price index of a basket of certain goods. So if you purchase goods included in the basket, you will notice that you pay 6% more, otherwise not necessarily.
Good day
How do I calculate this question: C= 100+5yd G= 2000 T= 2000 I(planned)=200.
Suppose the actual output is 3000. What is the level of planned expenditures at this level of output?

money as unit of account means what?
Kalombe
A unit of account is something that can be used to value goods and services and make calculations

all of you please speak in English I can't understand you're language

I want to know how can we define macroeconomics in one line
Muhammad
it must be .9 or 0.9
no Mpc is greater than 1
Y=100+.9Y+50
Y-.9Y=150
0.1Y/0.1=150/0.1
Y=1500

hi can someone help me on this question
If a negative shocks shifts the IS curve to the left, what type of policy do you suggest so as to stabilize the level of output?
discuss your answer using appropriate graph.
