Given that A = 21 +33–5k, Ē = -1 -2] + 3k and Y = 41+ 5j - 2k
Find
a.Ā+ Ē +Y
b. (A-E).(E+)
c. (Ā - Y)*E
d. The angle between E and Y​

a.) travels faster in solids because the particles are closer together.

air is a gas water is a liquid

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
