Answer:
The number of degrees of longitude that separates New York City from Denver, Colorado is 30.9843 degrees longitude
Explanation:
The longitude of New York City is 74.0060° W
The latitude of New York City is 40.7128° N
The longitude of Denver, Colorado is 104.9903°W
The latitude of Denver Colorado is 39.7392°N
Therefore, the difference the number of degrees of longitude that separates New York City from Denver, Colorado is 104.9903 - 74.0060 = 30.9843°.
wich if the following statements best describes why the mass of a bowling ball would not change if it were transported from earth to the moon?
gravity is constant forge
the bowling ball will adapt to the changes in gravity
matter is resistant and changes gravity
the amount of mattet in the bowling ball remains the same
Answer:
the amount of matter in the bowling ball remains the same
Explanation:
The reason why the mass of the bowling ball on earth and moon remains the same is that matter in the bowling ball remains the same.
Mass of any substance is the amount of matter it contains.
Since there is no loss in matter, the mass of the bowling ball anywhere in the universe will be the same. Only the weight changes due to differences in gravity.helpppppp i hate chemistry

Squeaky Clean. Rob waxes 20 floor tiles with Squeaky Clean and 20 tiles with the original wax brand.
After one week he counts the number of scratches on the floor. What is the independent variable?
number of floor scratches
brand of floor wax
20 tiles with original brand wax
Answer:
The correct answer is - brand of floor wax.
Explanation:
The independent variable is the variable or the factor in an investigation which is manipulated or change in the experiment and affects the dependent variable and produces a various result.
In this investigation, there are different brands of the floor was are the independent variable as they are changed to see the effect on the scratches on the floor on 20 tiles for each brand.

Describe the process of evaporation condensation, and precipitation
Answer:
eva... water to gaseous foum .... condensation liquid to solid and perp ..... water that is falling out of the sky, this could be rain, drizzle, snow, sleet, hail or something rarer!Answer:
Evaporation is a type of vaporization that occurs on the surface of a liquid as it changes into the gas phase. Precipitation is water released from clouds in the form of rain, freezing rain, sleet, snow, or hail. Condensation is the process by which water vapor in the air is changed into liquid water.
Explanation:
Why is NCl3 not soluble in water?
Answer:
Explanation:
NCl3 does not dissolve in water because it is a nonpolar molecule which is different with water. NCl3 is nonpolar due to the difference in electronegativities between 3 atoms of Cl and 1 atom if N2.
Answer:
A polar solute dissolves into a polar solvent and a non-polar compound dissolves into a non-polar solvent, this rule is known as "like dissolves like".
describe a habitat of giraffe or an elephant(i prefer the giraffe tho, and please make it reasonable)
Answer: Savanna, Woodland, or Grassland.
Giraffes eat new shoots and leaves, their habitat needs to have a good supply of trees -- they flock towards acacia trees in particular. Giraffes use their extremely long legs, necks and tongues to browse mainly from the thorns on the acacia tree. The tongue and the inside of the mouth are lined with tough tissue that protects against the thorns.
1. What part of the human body has the same role as the power source in a computer?
2.What part of the human body has the same role as the keyboard or the mouse on a computer?
Answer:
The heart
Hand
Explanation:
The part of the human body that has the same role as the power source in a computer is the heart. A power source in a computer provides energy that powers the whole system.
The human heart provides the pumping action for the circulatory system. Just like current passes through wires in a computer by energy from the power source, the human heart pumps blood throughout the body in a like manner. Without the pumping action of the heart, the human body is dead.Also, keyboard and mouse are input devices. They are used to give instruction and perform certain tasks on the computer system.
The human body can also carryout tasks by using the hand. Objects are moved from one place to another just as you drag an icon using the mouse. We type word processors using information from the keyboard, also, we are able write using pen on paper.Can anyone help me out?

A newspaper article about the danger of global warming from the accumulation of greenhouse gases such as carbon dioxide states that "reducing driving your car by 20 miles a week would prevent release of over 1000 pounds of CO2 per year into the atmosphere." Is this a reasonable statement? Assume that gasoline is octane (molecular formula is C8H18) and that it is burned completely to CO2 and H2O in the engine of your car. Facts (or reasonable guesses) about your car's gas mileage, the density of octane, and other factors will also be needed.
Answer:
The newspaper article's statement is correct since the mass of CO₂ reduced = 1071.85 pounds
Explanation:
Equation for the combustion of gasoline (octane) is given below:
2C₈H₁₈ + 25O₂ ----> 16CO₂ + 18H₂O
Density of C₈H₁₈ = 0.8 g/mL
Assuming mileage of the car is 20 miles/gallon; 1 gallon = 3.785 L
Since 20 miles is reduced in driving each week, thereby saving 1 gallon of gasoline, number of litres of gasoline reduced in a year is given by;
52 * 3.785 L = 196.82 L = 196820 mL
density = mass/volume; mass = density * volume
mass of gasoline saved = 0.8 g/mL * 196820 mL = 157456 g
number of moles = mass/molar mass
Molar mass of C₈H₁₈ = 114 g/mol
number of moles of C₈H₁₈ in 157456 g = 157456 g / 114 g/mol = 1381.2 moles
From the equation of reaction, 2 moles of C₈H₁₈ produces 16 moles of CO₂
1381.2 moles of C₈H₁₈ will produce 1381.2 * 16/2 moles of CO₂ = 11049.6 moles of CO₂
mass = number of moles * molar mass
molar mass of CO₂ = 44 g/mol
mass of CO₂ = 11049.6 moles * 44 g/mol = 486182.4 g
1 g = 0.00220462 pounds
Therefore mass of CO₂ reduced = 486182.4 g * 0.00220462 lb/g
mass of CO₂ reduced = 1071.85 pounds
Therefore, the newspaper article's statement is correct

An isotope of Cesium -137 has a half-life of 30 years. If 1.0 g of Cesium – 137 disintegrates over a period of 60 years, how many grams of Cesium- 137 would remain?
Answer:
Explanation:
Radioactive decay follows the equation:
Ln [A] = -kt + ln [A]₀
Where [A] is amount of isotope after time t: Our incognite,
k is rate constant: ln 2 / Half-life = 0.0231 years⁻¹
t are 60 years
[A]₀ is initial amount of isotope: 1.0g
Replacing:
Ln [A] = -kt + ln [A]₀
Ln [A] = -0.0231 years⁻¹*60 years + ln 1.0g
ln [A] = -1.386
[A] = 0.25g

When propane is reacted in the presence of oxygen gas, the products of this combustion reaction are: A. CO + H2O B. CO2 + H2O C. C2H4 + H2O D. CH4 + H2O
Answer:
B. CO2 + H2O
Explanation:
Propane is an hydrocarbon as it contains only v=carbon and hydrogen atoms.
Whenever an hydrocarbon reacts with oxygen or undergoes a combustion reaction, two products are always formed only,
These two products are;
Carbon dioxide (CO2) and water (H2O)
This means the correct option is option B.
