electromagnet in each situation.
iron nail Using a battery with a higher voltage:
weaker force of attraction"
Wrapping the wire around the nail only three times:
wire
Changing the direction of the current by reversing the
battery connections:
Using a plastic stick in place of the iron nail:
Holding the nail vertically rather than horizontelly:

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.

answer: he is 272195

step-by-step explanation: all you have to do is multiple 3535 and 77 and it equals 272195
