There are a total of 12 chairs in each row, and the scenario is represented by the equation 8c = 96.
What is algebraic Expression?Any mathematical statement that includes numbers, variables, and an arithmetic operation between them is known as an expression or algebraic expression. In the phrase 4m + 5, for instance, the terms 4m and 5 are separated from the variable m by the arithmetic sign +.
Given, there are 96 chairs and all Kayla wants there to be eight rows.
Let "c" be the number of chairs in each row,
Since there is a total of 96 chairs and 8 rows.
The equation for the situation is:
8 *c = 96
So,
In 8 rows there are a total number of chairs = 96
In each row, there are a total number of chairs = 96/8
In each row, there are a total number of chairs = 12
Therefore, the equation that represents the situation is 8c = 96 and there is a total of 12 chairs in each row.

The head of a 245 g golf club traveling at 62 m/s just before it strikes a 48 g golf ball at rest on a tee. After the collision, the club travels in the same direction at 43 m/s. Use the law of conservation of momentum find the speed of the golf ball just after impact.
Answer:
The speed of the golf ball just after impact is 96.98 m/s
Explanation:
Given;
mass of the club, m₁ = 245 g = 0.245 kg
initial velocity of the club, u₁ = 62 m/s
mass of the golf ball, m₂ = 48 g = 0.048 kg
initial velocity of the golf ball, u₂ = 0
final velocity of the club, v₁ = 43 m/s
let the final velocity of the golf ball
Apply the law of conservation of momentum;
m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂
0.245(62) + (0.048 x 0) = 0.245(43) + 0.048v₂
15.19 = 10.535 + 48v₂
15.19 - 10.535 = 48v₂
4.655 = 48v₂
v₂ = 4.655 / 0.048
v₂ = 96.98 m/s
Therefore, the speed of the golf ball just after impact is 96.98 m/s

NEED HELP!?Which of the following combinations would result in the greatest acceleration?
A 60N & 2.0kg
B 1N & 0.20kg
C 5N & 0.35 kg
D 12N and 1.0 kg
Answer:
The greatest acceleration is presented in option A 60N & 2.0kg
Explanation:
The second Newton's law relates the net force F exerted on an object of mass m and the acceleration it has by the equation:
F=m.a
The acceleration is found by solving the equation for a:
[tex]\displaystyle a=\frac{F}{m}[/tex]
Let's compare the different options and choose the greatest acceleration.
A F= 60 N, m= 2 Kg.
[tex]\displaystyle a=\frac{60}{2}=30\ m/s^2[/tex]
B F= 1 N, m= 0.20 Kg.
[tex]\displaystyle a=\frac{1}{0.2}=5\ m/s^2[/tex]
C F= 5 N, m= 0.35 Kg.
[tex]\displaystyle a=\frac{5}{0.35}=14.29\ m/s^2[/tex]
D F= 12 N, m= 1 Kg.
[tex]\displaystyle a=\frac{12}{1}=12\ m/s^2[/tex]
The greatest acceleration is presented in option A 60N & 2.0kg
A 438 gram ball is traveling east at 39 m/s when it is hit by a 2.4 kg softball bat. After being in contact with the bat for 302 ms, the ball rebounds at a speed of 28 m/s.
Determine the impulse vector (magnitude and direction) in kg*m's felt by the bat. Treat east as the positive direction.
Answer:
The magnitude of the impulse vector of the bat is 29.346 kg.m/s
The direction of the impulse vector of the bat is in the initial direction of the ball before impact
Explanation:
The given parameters are;
The mass of the ball, m₁ = 438 g
The speed of the ball = 39 m/s
The mass of the softball bat = 2.4 kg
The time of contact = 302 ms = 0.302 seconds
The speed of rebound = 28 m/s
The impulse = The change in momentum = Δp = F × Δt = m × Δv
The impulse on the ball = m₁ × Δv = 0.438 × (39 - (-28)) = 29.346 kg·m/s
Given that force of reaction of the bat is in opposite direction but equal to the force of the ball, and the time and the duration of contact with the ball is the same for both the ball and the bat, the impulse vector ore equal and opposite
Therefore, the magnitude of the impulse vector of the bat = 29.346 kg.m/s
The direction of the impulse vector of the bat = The initial direction of the ball before impact.
A sound wave is produced in a metal cylinder by striking one end. Which of the following occurs as
the wave travels along the cylinder?
a. Its frequency increases
b. It transfers matter
C. It transfers energy
d. Its amplitude increases
Answer:
C. It transfers energy
Explanation:
As the metal cylinder is strike at one end, energy is being transferred.
A wave is a disturbance that transmits energy from one point to another. All waves are prominent for their energy transfer potentials. Waves do not move materials of the medium. The frequency of the wave does not increases same with the amplitude. The most important thing about a wave is the ability to transmit energyThe focus of an earthquake is the: center of the earthquake point on the surface directly above the earthquake point underground where the earthquake starts direction the seismic waves travel
Answer:
B. point on the surface directly above the earthquake
Explanation:
The earthquake involves the propagation of waves through the inner part of the earth due to natural or artificial processes. This majorly leads to the vibration of the earth crust of the affected region as the waves propagates. Thereby, causing sometimes the a violent break up of the surface of the earth from within.
Therefore, the focus of an earthquake is majorly called its epicenter, which is a point on the surface directly above the earthquake itself.

Someone please answer it’s due today and I am so confused
The force used by the girl in pushing the box is 294 Newtons.
Hence, option M) 294N is the correct answer.
What is force?Force is simply a push or pull capable of changing the state of rest or motion of an object.
From Newton's second law of Motion;
F = ma
Where m is mass of object and a is acceleration.
Given the data in the question;
Mass of box m = 42kgAcceleration a = 7m/s²Force applied F = ?We substitute our given values into the expression above.
F = ma
F = 42kg × 7m/s²
F = 294kgm/s²
F = 294N
The force used by the girl in pushing the box is 294 Newtons.
Hence, option M) 294N is the correct answer.

which acid is dangerous between vinegar,pure water,lemon juice and milk?
Answer:
Explanation:
Oftentimes when people hear that something has a low or high pH, they worry that it is dangerous. But this is not the case, pH alone cannot tell you if a substance is dangerous or not. Anyway, bases are typically considered more dangerous than acids! But what is pH? A substances pH is simply the concentration of hydrogen ions (H+) of the material when in solution (usually water). It is a numeric (logarithmic) scale used to specify how acidic or basic an aqueous solution is and an aqueous solution is just a solution where water is the solvent.
