Two coins are knocked off a table at the same time by different forces. which coin will hit the ground first?
Final answer:
Two coins knocked off a table by different forces will hit the ground simultaneously because gravity affects each coin equally, and the horizontal and vertical components of their motion are independent. This is consistent with the universality of free fall and has been empirically demonstrated by repeated experiments.
Explanation:
Do Different Forces Affect Gravity's Impact on Falling Objects?
When two coins are knocked off a table simultaneously with different horizontal forces, their subsequent motion comprises both horizontal and vertical components. However, gravity acts only on the vertical motion, and it does so equally on both coins regardless of their horizontal velocities. According to the laws of physics, specifically Galileo's theory of falling bodies, both coins will hit the floor at the same time because the horizontal and vertical motions are independent of each other. This phenomenon is due to the universality of free fall, which states that all objects accelerate at the same rate under gravity's influence, ignoring air resistance.
An important point to note is that factors such as air resistance can affect the time it takes for objects with different shapes and surface areas to hit the ground. However, in the case of the coins, since they are identical and their shapes do not change as they fall, air resistance does not play a significant role, and thus they hit the ground simultaneously. This was demonstrated by Galileo and can be observed in everyday life, such as by dropping a shoe and a coin side by side.
Solve the following system of equations. Enter the y-coordinate of the solution. Round your answer to the nearest tenth. 5x+2y=7 -2x+6=9
Answer:
y = 1.7
Step-by-step explanation:
Given : 5x+2y=7 and - 2x+6=9.
To find : Solve the following system of equations. Enter the y-coordinate of the solution. Round your answer to the nearest tenth.
Solution : We have given
5x + 2y = 7 --------(1)
- 2x + 6y = 9 -------(2).
To make the y coefficient same multiply the equation 1 by 3.
15 x + 6y = 21 .
(+)-2x +(-) 6y = (-)9 .
______________ ( On subtracting both the equations )
17 x + 0 = 12 .
17 x = 12 .
On dividing both sides by 17
x = [tex]\frac{12}{17}[/tex].
x = 0.705
Plug x = 0.705 in equation 2 .
- 2 ( 0.705) + 6y = 9.
-1.41 + 6y = 9 .
On adding both sides by 1.41.
6y = 9 + 1.41
6 y = 10. 41
On dividing both sides by 6.
y = [tex]\frac{10.41}{6}[/tex].
y = 1.735.
Nearest tenth = 1.7
Therefore, y = 1.7.

on a map with a scale 1:100,000 the distance between two cities is 12cm. what would be the distance between these two cities on a different map with a scale 1:300,000?
Part 1)
we have
the scale is [tex]1:100,000[/tex]
the distance on a map is [tex]12\ cm[/tex]
we know that
The scale is equal to the distance on a map divided by the real distance
Let
x------> distance on a map
y-------> real distance
S-------> scale
[tex]S=\frac{x}{y}[/tex]
In this part we have
[tex]S=\frac{1}{100,000}[/tex]
[tex]x=12\ cm[/tex]
Find the value of y
[tex]y=\frac{x}{S}[/tex]
Substitute the values
[tex]y=\frac{12}{(1/100,000)}[/tex]
[tex]y=1,200,000\ cm[/tex]
Convert to kilometers
[tex]y=12\ Km[/tex]
Part 2)
In this part we have
[tex]S=\frac{1}{300,000}[/tex]
[tex]y=12\ km[/tex]
Find the value of x
[tex]x=S*y[/tex]
Substitute the values
[tex]x=(1/300,000)*12[/tex]
[tex]x=0.00004 Km[/tex]
Convert to centimeters
[tex]x=4\ cm[/tex]
therefore
the answer is
The distance is [tex]4\ cm[/tex]

There 430 people in wave pool. Write an inequality that represents how many more people p can enter the pool.
Let
p--------> number of additional people who can enter the pool
we know that
the maximum capacity of the pool is [tex]600\ people[/tex]
so
the inequality is
[tex]430+p \leq 600[/tex]
[tex]p \leq 600-430[/tex]
[tex]p \leq 170[/tex]
the solution is the interval ----------> (-∞,170]
but remember that the number of people can't be a negative number
so
the solution is the interval -------> [0,170]
therefore
the answer is
The inequality is equal to [tex]430+p \leq 600[/tex]
how much is 81% of 403? find the missing element in the following base-rate-percentage problem. round the answer to the nearest hundredth.
Find 81% of 403 by converting the percentage to a decimal (0.81) and then multiplying it by 403, which equals to 326.43 when rounded to the nearest hundredth.
Explanation:The student is asking for the solution to determine the value of 81% out of 403. This is a simple proportional math problem and could be solved with the following steps:
Convert the percentage (81%) to its decimal equivalent. This is done by dividing the percentage by 100. So, 81 divided by 100 equals 0.81.Multiply the given total number (403) by the decimal equivalent of the percentage. So, 0.81 times 403 equals 326.43.So, 81% of 403 is approximately 326.43, rounding to the nearest hundredth.

The word geometry has eight letters. Three letters are chosen at random. What is the probability that two consonants and one vowel are chosen?
Answer: [tex]\dfrac{15}{28}[/tex]
Step-by-step explanation:
The given word : geometry
Total letters in the above word = 8
Number of vowels (a e i o u) in word =3
Number of consonants = 5
Number of ways to choose two consonant and one vowel is given by :-
[tex]F=^5C_2\times^3C_1\\\\=\dfrac{5!}{2!(5-2)!}\times (3)\ [ \because ^nC_1=n]\\\\=5\times2\times3=30[/tex]
Number of ways to choose any three letters from the 8 alphabets:-
[tex]T=^8C_{3}=\dfrac{8!}{3!(8-3)!}=8\times7=56[/tex]
Now, the probability that two consonants and one vowel are chosen :-
[tex]=\dfrac{F}{T}\\\\=\dfrac{30}{56}=\dfrac{15}{28}[/tex]
Hence, the required probability = [tex]\dfrac{15}{28}[/tex]
Suppose that the sample space is s = {a, b, c, d, e, f, g, h} and that outcomes are equally likely. find the probability of the event e = {b, f, h}.
The probability of the event E = {b, f, h} with the sample space S = {a, b, c, d, e, f, g, h} is 3/8 or 0.375.
Explanation:The student has asked to find the probability of the event E = {b, f, h} given the sample space S = {a, b, c, d, e, f, g, h} where all outcomes are equally likely. To calculate the probability, we need to use the formula for theoretical probability, which is the number of favorable outcomes divided by the total number of possible outcomes in the sample space.
We see that the event E has 3 outcomes (b, f, h) and the sample space S has 8 outcomes. So the probability of event E is given by:
P(E) = Number of outcomes in E / Number of outcomes in S = 3 / 8 = 0.375

Evaluate the expression for the given values of the variables.
4(2m-n)-3(2m-n);
m=-15 n=-18
A. 3
B. -3
C. -12
D. 16
The result of evaluating the expression 4(2m-n)-3(2m-n) with respect to m=-15 and n=-18 is -12.
Explanation:To evaluate the expression 4(2m-n)-3(2m-n) for m=-15 and n=-18, we first substitute these given values into the expression.
Therefore, our expression becomes 4(2*(-15) - (-18)) - 3(2*(-15) - (-18)). Simplify the expression in the parentheses first according to the order of operations (also known as BEDMAS or PEMDAS) which stands for Brackets/parentheses, Exponents/Orders, Division/Multiplication, Addition/Subtraction.
4(2*-15 - (-18)) - 3(2*-15 - (-18)) simplifies to: 4(-30 +18) - 3(-30 + 18). Further simplify to: 4*-12 - 3*-12.
Then, doing the multiplication gets: -48 - (-36), which simplifies to: -48 + 36. Therefore, the value of the expression is -12.

Why would the owner withdraw assets from other cash?
Answer:
The owner of a business sometimes withdraw assets other than cash because cash is more liquid and can be used in transactions easily, whereas the assets after a period of times becomes liable of depreciation.
The depreciation on assets decreases the amount of the assets based on the time and wear and tear of the tangible assets.
Therefore, to retain some liquid assets in hand the tangible or intangible assets are used first.
Hence, the businessman here did the right thing.
What are the 3 consecutive integers of 135?
Three consecutive integers can be represented as followed.
X → first integer
X + 1 → second integer
X + 2 → third integer
Since the sum of our three consecutive integers is 135, we can set up an equation to represent this.
X + X + 1 + X + 2 = 135
-Simplify on the left-
3x + 3 = 135
-3 -3
3x = 132
÷3 ÷3 ← divide both sides by 3
X = 44
X + 1 = 45
X + 2 = 46
Therefore, the three consecutive integers are 44, 45, and 46.
