Imagine you need to explain to a friend how to convert a value on a food label to one that is measured in grams. Assume the package of food has a mass of 1.0 pounds. write an explanation for how to use dimensional analysis to convert this value to one expressed in grams.
Answer:
453.592 grams
Explanation:
Given
Mass = 1 lb
Required.
Convert to grams using dimensional analysis
Represent 1 lb with x g
In unit conversion, we have that.
1 lb = 453.592 g
So:
Getting the equivalent of lb in g, we have:
x g = 1 lb * (453.592 g/ 1 lb)
x g = 1 * 453.592 g
x g = 453.592 grams
Hence:
The equivalent of 1 lb in grams is 453.592 grams

describe the motion of objects that are viewed from your reference frame from both inside and while you travel inside a moving vehicle
Answer:
They don't move
Explanation:
it may look like they move but you are moving and you are passing the objects so they are not moving other wise things like some trains or animals they move with you. I hope this helps! :D
The motion of objects that are viewed from your reference frame from both inside and while you travel inside a moving vehicle are not moving. It seems that way because the car you are in is moving, but the surrounding things aren't moving unless they are people, animals, or other cars.
What is motion ?An object changing its position with regard to time is referred to as motion. In mathematics, displacement, distance, velocity, acceleration, and speed are used to explain motion.
Motion is the shift in an object's location with regard to time. Motion includes things like a book tumbling off a table, water running from the faucet, rattling windows, etc. Even the air we breathe has motion to it! The entire universe is in motion.
Because the two observers are using distinct frames of reference, the observations differ. Different frames of reference move in relation to one another. A frame of reference is a collection of coordinates that may be used to calculate the locations and velocities of objects within it.
Thus, The motion of objects that are viewed from your reference frame from both inside and while you travel inside a moving vehicle are not moving.

Do you think the density of the rock models affects the melting rate? Why or why not? I said no, but I need help on the part that says why or why not. Please use your own knowledge. Looking it up won't help. I have tried. :)
Answer:
1) Yes the density does affect it's melting rate.
Explanation:
Simply because the more rock the more time. For instance an ice cube that is empty inside ( has less density ) will take less to melt. Verses an ice cube that is ice to its inner core ( has more density ) will take more time to melt in the same temperature as the first ice cube.
So far, he spent 3 hours reading the first 165 pages. If Kamal continues to read at the same rate, how many more minutes will he need to finish the 198-page book?
Answer:
36 minutes
Explanation:
You take 165/3= 55 pages per hour.
Take 198-165 = 33 pages left of the book
Take 33/55 = .6 hrs to finish the book.
Take 60(minutes in an hour)*.6= 36 minutes

You have 150 g of water (m). The specific heat of the water is 4.184 g/jC (c) . You heat the water and raise the temperature by 1 degree. How much heat did the water absorb?
Answer:
627.6J
Explanation:
q=mcΔT
where:
q = heat energy (J)
m = mass (g)
c = specific heat (g/j*C)
Δt = change in temperature (C/K)
q= (150)(4.184)(1) = 627.6

What is the difference between the dependent variable and the independent variable in an experiment?
An independent variable is the cause. Its value is independent of other variables in your study. A dependent variable is the effect. Its value depends on changes in the independent variable
Explanation:Variables are the factors or the numbers used as a quantity. The dependent variables are conditional, and the independent variable is the cause that affects the result.
What are dependent variables and independent variables?The independent variable of an experiment is the data that is the cause of the experimental design. Its value and result do not depend on other factors and conditions. These values are manipulative and are set by the researcher.
The dependent variables, on the other hand, vary based on the other factors and variables and are the effect that is based on the response and the outcome of the other variables. It is the tested or the measured value.
Therefore, the independent and dependent variables differ based on cause and effect.

Water is an example of a mixture because it is made up of hydrogen and oxygen atoms bonded together. (4 points)
O True
O False
Answer:
False
Explanation:
The mixture is defined as a chemical substance formed by the combination of two or more substance but do not form any bond together.
Water is not a mixture because the water molecule is consists of two hydrogen (H2) atoms and one oxygen (O) atom bonded together with hydrogen bonds.
Hence, the given statement is "false".

Find the exact value. tan(−300∘)
Explanation:
tan(-300) = tan(-300+360) = tan (60)
here we added 360 degree. where by adding 360 +or- (n×360) to the any angle nothing will change as they called equivalent angles
equivalent angles is by adding +or- n×360 to any angle is equivalent to that angle so tan(-300) = tan(60) then we will calculate tan(60) on the calculator
