If a 1200 kg car is moving at 28 m/s when it hits a truck, resulting in a 20,000 n force that slows the car down to 10 m/s, for how long did the car experience the force?
Answers
If a 1200 kg car is moving at 28 m/s when it hits a truck, resulting in a 20,000 n force that slows the car down to 10 m/s, then the car experienced the force for 1.08 seconds.
To calculate the time the car experienced the force, we can use the formula:
Force (F) = Mass (m) × Acceleration (a)
First, we need to determine the acceleration, which is the change in velocity divided by time:
a = (final velocity - initial velocity) / time
a = (10 m/s - 28 m/s) / time
Since we know the force and mass, we can now find the time:
20,000 N = 1200 kg × ((10 m/s - 28 m/s) / time)
Rearrange the equation to solve for time:
time = (1200 kg × (10 m/s - 28 m/s)) / 20,000 N
time = (1200 kg × (-18 m/s)) / 20,000 N
time = -21,600 kg·m/s / 20,000 N
time = 1.08 s
The car experienced the force for 1.08 seconds.

Which of the following played sound recorded on wax cylinders?
A.television
B.radio
C.printing press
D.phonograph
Please help me it’s for music
Answers
Phonograph played sound recorded on wax cylinders. Option (D) is correct for the question.
What do you mean by Radio?Radio is a form of sound transmission over radio waves that often involves the distribution of music, news, and other programming from a single broadcast station to a large audience of listeners with radio receivers.
When the cylinder is turned, the stylus pushes into the wax and creates a groove. The stylus vibrates along with the sound and moves very slightly up and down as well, recording the sound in the groove on the wax.
Thomas Edison came up with the idea for the phonograph on July 18, 1877, when he was testing waxed paper. The recordings were made on the outside of a strip of tinfoil that had been wound around a rotating metal cylinder in the early production versions.
Therefore, Option (D) is correct. Phonograph played sound recorded on wax cylinders.

Answers
The values of a and b from the quadratic equation x² + (13/2)*x + 15/2 = 0 are:a = -10/13 and b = -3/13 respectively.
How to solve the quadratic equation?For a general quadratic equation:a*x² + b*x + c = 0
The solutions are:
\(x = \frac{-b \pm \sqrt{b^2 - 4ac} }{2a}\)
In this case, we have the quadratic equation:
x² + (13/2)*x + 15/2 = 0.
Replacing that in the quadratic formula for the solutions, we will get:
\(x = \frac{-13/2 \pm \sqrt{(13/2)^2 - 4*1*15/2} }{2*13/2}\\\\
x = \frac{-6.5 \pm 3.5 }{13}\)
Then the two solutions are:
x = (-6.5 - 3.5)/13
= -10/13
x = (-6.5 + 3.5)/13
= -3/13
Therefore, the solution to the quadratic equation is = -10/13 and b = -3/13

A circle has a circumference of 12. It has an arc of 8/5
What is the central angle in the arc?
Answers
Answer:
14.3 degrees.
Explanation:
To find the central angle of an arc, we need to use the formula central angle = arc length / radius * 180/π. In this case, the radius of the circle is 12/2π = 2, so the central angle of the arc is 8/5 / 2 * 180/π = 14.3 degrees.
Answer:48 degrees
Explanation:The central angle of the arc is 48 degrees.
Step-by-step explanation: The question has provided the first clue, which is the circumference of the circle, given as 12 units. Also the length of an arc along the same circumference has been given as 8/5 units. The circumference of a circle is calculated as
Circumference = 2Pi x radius
Also the length of an arc is calculated as
Length of an arc = (X/360) x 2Pi x radius (where ‘X’ is the angle subtended by the arc).
Having known the answer to 2Pi x radius which is 12, and the length of the arc which is 8/5, we can now express the length of an arc as
Length of an arc = (X/360) x 2Pi x radius
8/5 = (X/360) x 12
By cross multiplication we now have
(8 x 360)/ (5 x 12) = X
2880/60 = X
48 = X
Therefore the central angle of the arc is 48 degrees.
In a certain language “SUDAN” is coded as “45” and “ITALY” is coded as “9”. What will be the code for the “EGYPT” in that language?
who will tell in 4 minutes will be marked as brainliest
Answers
Answer:
If we consider each letter in the word "SUDAN" and "ITALY" as a digit, where "A" is represented by 1, "B" by 2, and so on, then we can add up the digits in each word to get their respective codes.
For "SUDAN," we have:
S = 19
U = 21
D = 4
A = 1
N = 14
Adding these up, we get:
19 + 21 + 4 + 1 + 14 = 59
So "SUDAN" is coded as "59."
For "ITALY," we have:
I = 9
T = 20
A = 1
L = 12
Y = 25
Adding these up, we get:
9 + 20 + 1 + 12 + 25 = 67
So "ITALY" is coded as "67."
Now, for "EGYPT," we have:
E = 5
G = 7
Y = 25
P = 16
T = 20
Adding these up, we get:
5 + 7 + 25 + 16 + 20 = 73
So "EGYPT" is coded as "73."

Explanation:
Based on the code given , it appears that there are no syntax errors. However, there are a few issues that might cause runtime errors:
The class "SolitaireFrame" might not be defined or imported properly.The class "Card" might not be defined or imported properly.The method "initialize()" might not be defined or implemented correctly.The class "Stack" might not be defined or imported properly.The variable "thePile" might not be initialized before use.The elements at i and j in the swap method might not be within the bounds of the stack.What is the runtime errors?The code creates an instance of a class called "Solitaire" and calls its constructor, which in turn initializes the window and calls the "initialize()" method. It then calls the "addCard()" method to add a card to a stack called "thePile".
Therefore, It also contains a swap method which is used to swap elements in a stack. The error message "runtime errors in the code" is not specific enough to determine the cause of the problem.

A football is kicked into the air and the football's height, h, in feet, is given by the equation
h = -9.8t² + 24.5t where t is the time in seconds since the ball was kicked. After how many
seconds will the football land?
Answers
Answer:
h(t) = -4.9t^2 + 24.5t + 1
d(h)/dt = -4.9*2*t + 24.5
Max height is when d(h)/dt = 0
so -9.8*t + 24.5 = 0
t = 24.5/9.8 = 2.5 seconds

A football is kicked into the air and the football's height, h, in feet. After 2.5 seconds, the football will land.
What is a mathematical equation?Equations are statements in mathematics that have two algebraic expressions on either side of the equals (=) sign. It shows that the expressions printed on the left and right sides have an equal relationship.
Some of the elements of an equation are coefficients, variables, operators, constants, terms, expressions, and the equal to sign. When creating an equation, the "=" symbol and terms on both sides are a need.
h(t) = -4.9t² + 24.5t + 1
d(h)/dt = -4.9 x 2 x t + 24.5
Max height is when d(h) / dt = 0
so -9.8 x t + 24.5 = 0
t = 24.5 / 9.8 = 2.5 seconds
Therefore, the football will land after 2.5 seconds.
