What is Newton's 1-3rd laws of motion? Give examples for each
Answer:
In the first law, an object will not change its motion unless a force acts on it
In the second law, the force on an object is equal to its mass times its acceleration
In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction.

How do coastal sand dunes form in Florida?
Answer:
They are formed by windblown sand collecting around an obstruction. As organic matter is deposited by wind and waves, low herbs colonize the dune. As these plants collect more sand and organic matter, the dune increases in height becoming the fore dune.

You bought your pig and it weighed 82 pounds. By fair your goal weight is 267 pounds. Your pig will gain 1 pound for every 3 pounds of feed. How much feed will you need to get your pig to it's goal weight? (show your work) (5) Feed costs $21.37 per 50 pound bag. How much will your feed cost be, to get your pig to it's goal weight? (5) MUST SHOW ALL WORK.
Number of feed = 555 pounds
Feed cost = $237.21
Further explanationThe main composition of algebraic expressions are:
• 1. phrases/terms
• 2. variable
• 3. constants
• 4. arithmetic operations
• 5. coefficients
• 6. exponent
Initial weight = 82 pounds
Goal weight = 267 pounds
The difference in weight that must be achieved :
[tex]\tt 267-82=185~pounds[/tex]
The pig will gain 1 pound for every 3 pounds of feed⇒ 1 pound weight=3 pounds of feed
The amount of feed must be given:
[tex]\tt 185~pounds~weight\times 3~pounds~feed=555~pounds~of~feed[/tex]
Feed costs $21.37 per 50 pound bag, so for 555 pounds :
[tex]\tt (555~pounds\div 50)\times \$21.37=\$237.21[/tex]

what are the products of cellular respiration?
Answer:
During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell. Carbon dioxide and water are created as byproducts. In cellular respiration, glucose and oxygen react to form ATP. Water and carbon dioxide are released as byproducts.
Explanation:
In cellular respiration,glucose and oxygen react to form ATP*. Water and Carbon dioxide are released as byproducts.The three stages of aerobic respiration are glycolysis , the krebs cycle , and oxidative phosphorylation.

On the moon,When dropped from the same height Why does a flat sheet of paper fall more slowly than the same sheet when it is tightly crumpled into a ball?
Answer:
It all comes down to form. When the paper is smooth, it exposes a large surface to the air beneath it which slows its descent. Once it is crumpled, the surface which comes in contact with the air is much smaller, allowing it to fall much faster.

What is responsible for the blue sky?
Answer:
The blue color of the sky is caused by the scattering of sunlight off the molecules of the atmosphere.
Explanation:
Answer:
sun shine
Explanation:
Sunlight reaches Earth's atmosphere and is scattered in all directions by all the gases and particles in the air. Blue light is scattered more than the other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time

1. How much energy (in KJ) is required to convert 50.0g of ice at – 30 ˚C to
steam at130˚C.
Answer:
How much heat energy required to convert following?
How much heat energy, in kilojoules, is required to convert 47.0 g of ice at -18.0 C to water at 25.0 C ?
Specific Heat of Ice - 2.09 j/g * c
This is how I did it and the answer is wrong...Please check and correct me
Q = m * Cice * Change in Temp
Q = (47.0 g)(2.09 J/g*c)(43) = 4222.6 J * 0.001 kj / j = 4.22 kj

In carbon dioxide, how many grams of oxygen would there be if there are 24
grams of carbon?
a 55 g
b 73 g
c 64 g
d 88 g
Answer:
c. 64 grams
Explanation:
What is the proper combining ratio (by mass) for carbon to oxygen in the reaction that forms carbon dioxide (CO 2)? From the data given in question 1, since 64 grams of oxygen reacts with 24 grams of carbon, the ratio must be 64 to 24, which is 2.7 parts oxygen to 1 part carbon.

Darryl finds a bottle of what looks like clear water, with dirt settled at the bottom. When he shakes the bottle, the water gets dirty. Which term best describes the matter in the bottle?
A.homogeneous mixture
B.heterogeneous mixture
C.element
D.compound
Answer:
The correct answer is Heterogeneous mixture
Explanation:
Heterogeneous mixture are those mixture in which:
Substance is distributed in non uniform manner.
Two distinct layers are formed
Thus when water and dirt are mixed together it results in the formation of a heterogeneous mixture and after sometimes two different layers will be observed.
Hence, in the bottle there is a heterogeneous mixture of water and dirt.
Use the balanced equation given below to solve the following problem; Calculate the volume in liters of CO produced by the reaction of 175 g of Sb2O3.
Sb2O3 + 3 C --> 2 Sb + 3 CO
40.3 L CO
7.81 L CO
20.2 L CO
13.4 L CO
Answer: 40.3 L
Explanation:
To calculate the moles :
[tex]\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}[/tex]
[tex]\text{Moles of} Sb_2O_3=\frac{175g}{291.5g/mol}=0.600moles[/tex]
[tex]Sb_2O_3+3C\rightarrow 2Sb+3CO[/tex]
According to stoichiometry :
1 moles of [tex]Sb_2O_3[/tex] produces = 3 moles of [tex]CO[/tex]
Thus 0.600 moles of [tex]Sb_2O_3[/tex] will produce=[tex]\frac{3}{1}\times 0.600=1.80moles[/tex] of [tex]CO[/tex]
Volume of [tex]CO=moles\times {\text {Molar volume}}=1.80moles\times 22.4L/mol=40.3L[/tex]
Thus 40.3 L of CO is produced.
