Answer:

Option a. 0.5 m/s

Explanation:

This graph shows a straight line, where "Y" axis would be "Position" and "X" graph would be "Time". The ecuation that would describe this straight line is Y= aX + 1 , where "a" is the slope or inclination for this graph, and would give us the speed of the object

How do we find the slope (and hence, the speed)?: if you notice this graph, you will check that:

-When X (Time) is zero, Y (Position) is 1

-When X (Time) is 2, Y (Position) is 2

With these 4 points, you can calculate the slope (which will call "m") for this graph with:

m = (Y2-Y1)/(X2-X1)   so: Y2=2, Y1=1, X2=2, X1=0

Which gives us: m=1/2 (0.5), the slope or speed of the object: 0.5 m/s

Which of these is a chemical property? color, compressibility, heat of combustion, malleability
Flauer [41]
Chemical changes only happen when the object changes form. Color is a physical property because you're not changing the object that you have, compressibility is also a physical property because you still have the same substance before and sfter, malleability again is another physical. Heat of combustion is physical, when you burn things it changes the substance. :)

Goshia [24]
The  atomic  number  of  calculated as  number  of  protons  +  number  of  neutrons. The  number  of  protons  are  the  same  as  atomic  number.  This  implies  that  Nitrogen  has  seven  protons.  To  get  the  the  number  of  neutron  we minus  atomic  mass  from  number  of  protons
     that  is  14-7=7  neutrons
