Explanation:
Let's establish that x= number of polio vaccinations and y=number of measles vaccinations.
Since Dr. P gave a total of 60 VACCINATIONS, we know that x+y=60. (This is equation #1)
We also know that Dr. P gave a total of 184 DOSES of the vaccinations and that the polio vaccine has 4 doses, while the measles vaccine has 2 doses. This means that our second equation is 4x+2y=184. (This is equation #2)
You can get either variable (x or y) by itself from equation #1. I always choose x.
x+y=60
-y. -y
x=60-y
Now we can plug our x value into equation #2.
4x+2y=184
4(60-y)+2y=184
240-4y+2y=184
240-2y=184
-240 -240
-2y=-56
/-2 /-2
y=28 measles vaccines
So we know that Dr. P administered 28 measles vaccines. We need to plug our y value back into equation #1 (or, to make it easier, our switched around equation) to find the number of polio vaccines.
x=60-y
x=60-28
x=32 polio vaccines
Explanation:
1) This is a synthesis reaction (two or more reactants combine to form a single product).
2) The coefficients are added to balance the reaction.
3) Adding the states of matter (solid, liquid, gas) will make the reaction more precise.
Answer:
The shear deformation is 
.
Explanation:
Given that,
Shearing force F = 600 N
Shear modulus 
length = 0.700 cm
diameter = 4.00 cm
We need to find the shear deformation
Using formula of shear modulus
Put the value into the formula
Hence, The shear deformation is .

This is called refraction. Some common examples of refraction are a straw appearing bent or cut once it enters water in a glass.
