In order to find the circumference of a circle you need to use the equation C=2πr.
Answer:
Explanation:
1.wrap bar magnet in a plastic baggie and remove the iron filings from the mixture by using a bar magnet. Place a small piece of scrap paper on the scale and “tare” the scale. Then place filings on the scrap paper and record (e) the mass of the iron filings. Don't throw out the iron–save it to be recollected.
2.When sand is added to water it either hangs in the water or forms a layer at the bottom of the container. Sand therefore does not dissolve in water and is insoluble. It is easy to separate sand and water by filtering the mixture. Salt can be separated from a solution through evaporation.
3.Sand (mostly silicon dioxide) is not.
Pour the salt and sand mixture into a pan.
Add water. ...
Heat the water until the salt dissolves. ...
Remove the pan from heat and allow it to cool until it's safe to handle.
Pour the salt water into a separate container.
Now collect the sand.
Pour the salt water back into the empty pan.
Heat the salt water until the water boils. Continue boiling it until the water is gone and you're left with the salt.
Another way you can separate the salt water and sand is to stir up the sand/salt water and pour it through a coffee filter to capture the sand.
Answer:
B) x^2+6x+8
Explanation:
x-4 | x^3+2x^2-16x-32
- x^3-4x^2 <-- (x-4)(x^2)
_________________
6x^2-16x-32
- 6x^2-24x <-- (x-4)(6x)
_________________
8x-32
- 8x-32 <- (x-4)(8)
___________________________
0 | x^2+6x+8
This means the answer is B) x^2+6x+8
Answer:
The height of the bag is 1.466 m.
Explanation:
Given that,
Acceleration of gravity 
Pressure = 14800 Pa
Specific gravity = 1.03
We need to calculate the density
Using formula of specific gravity
Where, 
= density of solution
= density of water
Put the value in to the formula
We need to calculate the height
Using formula of pressure
Where, P = pressure
g = acceleration due to gravity
h = height
Put the value into the formula
Hence, The height of the bag is 1.466 m.
Answer:
if the weight of the object is equal to the force applied, there will be no change
if the force applied is less than the weight of the object, there won't be any change
if the force application ed is greater than the weight of the object, than the object will move.
Explanation:
here the weight referred to the force of the object.
