Answer:
(a) 1294.66 m
(b) 88.44°
Explanation:
d1 = 580 m North
d2 = 530 m North east
d3 = 480 m North west
(a) Write the displacements in vector forms
The resultant displacement is given by
magnitude of the displacement
d = 1294.66 m
(b) Let θ be the angle from + X axis direction in counter clockwise
θ = 88.44°
Locate the mode of 12, 3, 5, 17, 3, 18, 5, 11, 11, 15, 3, 9, 3.

A baryon is a particle consisting of three quarks or three antiquarks.
In order to form a neutral baryon (such as the neutron, which has electric charge zero), we must have two quarks with charge
(down, strange or bottom quark), and one quark with charge
(up, charm or top quark), so that the total charge will be zero:
A second possibility is to have a neutral baryon consisting of three antiquarks, of which two of them have charges
(anti-down, anti-strange or anti-bottom), and one of them has charge
(anti-up, anti-charm or anti-top), so that the total charge is still zero:
Matter is a lot like energy.
<em>It can't be created or destroyed</em>. It can only be moved around, shifted, rearranged, transformed, disguised, etc. Never created or destroyed.
If you suddenly see some matter that wasn't there a moment ago, it had to come from somewhere. It couldn't just appear out of nothing.
If you suddenly STOP seeing some matter that was there a moment ago, it had to go somewhere. It couldn't just disappear into nothing.
