Answer:
How can Mass and Speed Influence KE?
The goal of this experiment was to determine how mass and speed influence KE. This is significant because you would know whether to add more or less mass/speed if you were in a position where you required something to move higher. We filled the bean bag with a set amount of water, then dropped it to see how much mass it had. After that, you kept track of how high the bean bag went. The same thing happened with the speed, but the amount of liquid in the bottle was the same; it was just dropped from different heights. My theory is that the KE will increase as mass increases. This is also true of speed; if the bean bag is dropped from a higher altitude, it will launch farther than before.
The data I gathered in the lab confirmed my hypothesis. When the bottle's height was increased, the bean bag rose higher than before. I also tested four different masses: 0.125 kilograms, 0.250 kilograms, 0.375 kilograms, and 0.500 kilograms. The bean bag rose higher each time it was placed on a greater bulk.
On the speed test, the bean bag would frequently go higher than the bottle drop point, but not always. Furthermore, when it was dropped from the same height each time, the results differed significantly, for example, when it was dropped from 1.28, the results were 1.14, 1.30, and 1.30. Mass, on the other hand, was all in the same number range, with the exception that the numbers were somewhat different.
I used the calculations KE= 12 mv2 and Ht v2/2g. The initial step was to compute an object's kinetic energy, using the formula m=mass v=speed. The second was to determine the height at which I needed to drop something in order to reach a specific speed, where Ht=Height and g=Gravitational Acceleration of 9.8 m/s2.
I utilized these to create tables that depicted relationships between various variables, such as mass and KE or speed and height. My data kept increasing the entire time I was conducting the lab; when there was more mass/speed, the table had greater numbers.
This proves that my first theory was correct: as m/s increases, KE increases accordingly because they are all linear. When the bean bag height exceeded the water bottle drop mark, I was taken aback.
To summarize, my theory was supported by my data. When more mass or speed was introduced, the data values increased. This means that if I wanted more kinetic energy for something, I'd know to increase the mass or the speed of the object that was supplying the energy.
This hypothesis is valid because when you have greater mass, you also have more energy. So, if you drop a baseball, it isn't very heavy, so it will only propel the bean bag a short distance. However, because a bowling ball is quite heavy and has a lot of energy when it falls, it would force the bean bag to fly very high.
To improve this experiment, I would create the lever from a smoother material so that energy is not lost due to friction from the wood rubbing together. Perhaps a scanner or video camera to better document how far the bean bag traveled. All of these would aid the lab in obtaining more precise results, and they might perhaps be used in the future.

Answer:
Rs 525.5518.5%Step-by-step explanation:
Given:
Rate of interest is rTime = 2 yearsSum = PP(c) = 738P(s) = 720Use formulas:
P(c) = P*(1 + r)²P(s) = P*(1 + r*2)Substitute the known values:
P(1 + r)² = 738 ⇒ P = 738/(1 + r)²P(1 + 2r) = 720 ⇒ P = 720/(1 + 2r)Eliminate P and solve for r:
738/(1 + r)² = 720/(1 + 2r)738(1 + 2r) = 720(1 + r)²Solving the quadratic equation we get:
r ≈ 0.185 (or 18.5%)Now find P:
P = 720/(1 + 0.185*2) ≈ 525.55Perform each operation. Express your answers the the correct number of significant figures

b.9.44 meters - 2.11 meters
c.1.36 meters + 10.17 meters
d.34.61 meters - 17.3 meters
Step-by-step explanation:
no calculator available ?
this is pure number typing. no problem to be solved, no trick or hidden meaning to be considered, nothing.
at least the way you were typing the "problem" definition. as there are clearly some issues with the phrasing, maybe something was missed.
but here it goes :
61.2 + 9.35 + 8.6 = 79.15 meters
9.44 - 2.11 = 7.33 meters
1.36 + 10.17 = 11.53 meters
34.61 - 17.3 = 17.31 meters
The solution to the operations are:
a 79.15 meters
b. 7.33 meters
c.11.53 meters
d. 17.31 meters
This '+' is the addition sign. For numbers that have this sign, add the numbers together. This '-' is the subtraction sign. For numbers that have this sign, subtract the numbers from each number.
In order to round off to two significant numbers, the numbers after the decimals should be two non-zero digits.
a 61.2 meters + 9.35 meters +8.6 meters = 79.15 meters
b. 9.44 meters - 2.11 meters = 7.33 meters
c. 1.36 meters + 10.17 meters = 11.53 meters
d. 34.61 meters - 17.3 meters = 17.31 meters

Answer:
CStep-by-step explanation:
This is because,
As,
Negative integers are -1, -2, -3, -4, -5 .......
Also,
0 is neither negative integer nor positive integer,
And,
Positive integers are 1, 2, 3, 4, 5 .........
Therefore here ,
We get two sets of NON - POSITIVE INTEGERS,
That is 0 ( neither negative nor positive) and -1, -2, -3, -4, -5 ........ (Negative integers)
So,
Set of ( .......... -5, -4, -3, -2, -1, 0 ) is non - positive integers.
Answer:
C
Step-by-step explanation:
We are given 5 negative values plus 0. Keep in mind that 0 is not positive or negative. A non-positive integer is any negative number plus zero which the set follows. C is the only logical answer. A is incorrect because a negative number cannot be a whole number. B is incorrect because while we have negative values, we also have 0 and as stated previously, its not a negative or positive value. D is also incorrect because a non-negative integer is any positive value and zero but again, we don't have any positive values.

Joan joined her school's band. She bought a viola for $72.21, and a song book
which was $7.25 with a $100 bill. How much change was Joan given?
Hello :D
To do this you need to add the cost of the violin and the song book.
$72.21 + $7.25 = $79.46
$100 - $79.46 = $20.54
The answer is $20.54. I hope this helps :)

If R is the midpoint of OS , RS = 2x - 4, ST = 4x – 1, and RT = 8x – 43, find QS.
Answer:
56
Step-by-step explanation:
The numerical length of QS is 128.
We have a Line Segment QT and a point R lies on the midpoint of QS.
We have to determine length of QS.
What is Mid - Point of a line?The mid - point of a line is a point that divides it into two parts of equal lengths.
According to question, we have -
RS = 2x - 4
ST = 4x – 1
RT = 8x – 43
Since, R is the midpoint of QS -
QR = RS = 2x - 4
QS = QR + RS = 2 x QR = 2(2x - 4)
Now -
ST = RT - RS
ST = 8x - 43 - 2x + 4
ST = 6x - 39
and
ST = 4x - 1 [Given]
Therefore -
6x - 39 = 4x - 1
6x - 4x = - 1 + 39
2x = 38
x = 19
Now -
QS = QR + RS = 2RS
QS = 2(2x - 4) = 2( 2 x 19 - 4) = 2(38 - 4) = 2 x 34 = 128
Therefore - QS = 128
Hence, the numerical length of QS is 128.

p - [tex]\frac{2}{3}[/tex] p = 10 ( multiply through by 3 to clear the fraction )
3p - 2p = 30 , that is
p = 30
and [tex]\frac{2}{3}[/tex] × 30 = 2 × 10 = 20
