part 2 of 2
find the y-coordinate of the
ity (as a multiple of a).
answer in units of a.

(,)

Step-by-step explanation:

Given data,

Side of square = a

center of gravity of x,y

=

=

now, find the center of mass of each plate

For plate 1

W = 10N

x- coordinate = a/2

y- coordinate = a+a/2 = 3a/2

For plate 2

W = 30N

x- coordinate = a+a/2=3a/2

y- coordinate = a+a/2 = 3a/2

For plate 3

W = 70N

x- coordinate = a+a/2=3a/2

y- coordinate = a/2

For plate 4

W = 60N

x- coordinate = a/2

y- coordinate = a/2

= = =

= = =

Therefor (,) will the center of  gravity

ha!

i just did this!

18. g

20. h 30 degree turn.

21. d 90 degree angles

and also 19 is a. a sphere not a cirlcle

hope i !

pls mark me brainiest

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.
