Answer: option A. r = 3x+2y
Explanation:
Vector r is plotted on the graph. On x-axis each small division corresponds to 1 unit. Similarly on y-axis, each small division corresponds to one unit.
The vector is the resultant of addition of its x and y components. we would draw perpendicular to the x-axis and y-axis from the head of vector r.
On x-axis, 
= +3 units
on y-axis, 
= +2 units
Hence, vector r can be written as: r = 3x + 2y . Correct option is A.
Explanation:
In order from highest to lowest energies the parts of electromagnetic spectrum are named as
Gamma rays,
X-rays,
ultraviolet radiation,
visible light,
infrared radiation,
and radio waves.
Microwaves are a subsections of radio waves. They are used in microwave ovens to heat the food items.
This is expected EM spectrum in field of science.
I think you can weigh it 3 and 3.
If they balance, choose set not used.
If not balanced, take the heavier side
then weigh 1 and 1
if balanced, stone not used, if not balanced, take the heavier side
hope this helps
