Elastic collisions are bouncy collisions and the two cars will fly away from each other with different velocities after the collision.
Elastic collisions must satisfy two conditions.
There are Two Simultaneous equations you must solve.
ΣMinitial = ΣMfinal
Both solutions show you the correct answer; but they show you to plug in the values before you do the algebra to solve for time.
(besides there is a much easier way - see below)
You should Never plug in the values first.
You should Always solve the equation for...
To find the inverse f-1(x) of f(x)
First, if you can graph it you can check if it even has an inverse.
To have an inverse a function must pass both
the Vertical Line Test (VLT)
One that you write yourself and is on a computer that has never been connected to the internet
and never had a disk, thumb-drive, or anything else connected to it.

Joan, what have ou done so far? What is your question.
We are not here to do the work for you. You are getting credit...
Humaira, why did you post the same question twice??????
If pipe A fills a 5 liter tank at 15 l/hr and runs for 100 min. (1 hr 40 min) it will fill the tank in 20 min. and overflow the 5 liter tank for the rest of the time. Pipe B won't be needed.
For the first question you are looking for the
absolute Difference in Percentages.
So just tell what the Difference between the Percentage rates Is.
For the second you are looking for the
In other words, by what Percent did the Percent Increase.
It will not go back to being free.
That is a symbol that you already own it, it is not on your phone, and it is being stored for you in the cloud in case you want to download it again.

This is a homework help site!...
For a rectangle the perimeter is 2H + 2W (H and W being the height and width).
For a circle the Perimeter (Circumference) is Pi•D.
For this window the D is equal to the W of the rectangle
and the rectangular part has only 3 sides
and the circular part is 1/2 the circumference...
My coding theory study was LONG ago but I am pretty sure you need to give us more.
Like what kind of problem are you studying,
What is the check matrix you refer to?
You want to mix 2 solutions and have them average out to 70%
Equal amounts would average 65% since (50+80)/2 = 65
That leads to one equation.
The other is amount of Fifty% + amount of
Eighty% = 100ml.
So Volumes: VF + VE = 100
and percents: ...
To find the zeros you need to find all values of x for which y=0
Do this by completely factoring the function,
then setting each of the factors equal to 0
solve for the x's and these are the zeros of the function.
If h(x) = f( g(x) )
then the inverse h'(x) is = to g( f(x) )
So we can find h'(1), or of 2 or 3
by substituting 1, 2, or 3 into the function h'(x)
and evaluating the function for those values of x.
BUT the function(s) isn't defined so we can't do the evaluation.
You have 3 unknowns a, b, and c
And you only have 1 equation. ==>> Can't be done.
You need one or more independent equation per unknown.
So here you would need 3 independent equations (or more).
OH - btw - that is "What ARE a, b, and c?"
We need to know if it is simple interest
$5,000 (0.07) = $350 per year or a total of
$5000 + 10 ($350) = $5000+$3500 = $8,500
OR if it is compounded interest
and if it is compounded each year,
twice a year, or...
# 1 is already factored.
So either 2b-3 = 0 or b+2 = 0 and these are the 2 answers for x.
#2 needs to be factored.
You need to look for 2 numbers that
multiply to give -48 and add to give +2
Possibly you are to use the Heisenberg Uncertainty Principle as the other answer explains.
But you state you are to use the equation (Δx) (Δp) > h/4π(pi)
Maybe you are being expected to do a standard calculation of measurement uncertainty.
If so ....
You cannot calculate...
We cannot give legal advice.
That sounds like THE question the lab is supposed to lead you to?
Shouldn't you use your lab data to explain that?
