This equation is a mathematical model for the motion of the ball. A model is a representation of a phenomenon or object. You can use this mathematical model to predict the location of the ball if you know the time, or the time when the ball will reach a certain position. Let's use this model to predict the time for the ball to reach the flag. You can do this by setting the position equal to the position of the flag in your trial. Then, use algebra to solve for t, the time when the ball is at that location. Show your work in the space below.

The four stages of technological design include:

• identifying a problem.

• Designing a solution.

• Implement, build, and test the design.

• Determine if solution met the need.

This is ur answer.....

Sound travels faster in steel than in water. Similarly, sound travels faster in water than in air. This is because in solids, the distances between the molecules are closer and thus the atoms are more densely packed than in gases and liquids

Answer:

S = 26.58 meters

Explanation:

Given the following data;

Initial velocity = 4.66 m/s

Acceleration = 5.66 m/s²

Time = 2.35 seconds

To find the distance travelled by the object, we would use the second equation of motion;

S = ut + ½at²

Where;

S represents the displacement or height measured in meters.

u represents the initial velocity measured in meters per seconds.

t represents the time measured in seconds.

a represents acceleration measured in meters per seconds square.

Substituting into the equation, we have;

S = 4.66*2.35 + ½*5.66*2.35²

S = 10.951 + (2.83 * 5.5225)

S = 10.951 + 15.629

S = 26.58 meters

The correct answer to this open question is the following.

Unfortunately, you did not attach the article or the text. You also forgot to attach the options for the question.

However, trying to help you we did some deep research and can comment on the following.

The statement that describes the central idea of the text is "Baseball can be explained and improved by collecting data and studying the natural laws at play in the sport."

You are referring to the article written by Stephen Ornes, of August 21, 2013, for Science News for Students.

The author refers to the idea that baseball and physics are related and can be understood through the "eyes" of science. Statistics bring interesting data to help understand the game.

And this idea is correct because today, baseball coaches and other sports coaches as is the case of football, use a series of statistics and data to better hire talent for their respective teams, as well as to better create plans and game strategies derived from the results and interpretation of data.

Answer:

According to Newton's third law, throwing the apples in the opposite direction to the shore with a force, F₁, one after the other, repeatedly, pushes the both towards the shore with a force also equal to F₂ until the boat reaches the shore

Explanation:

The given parameters are;

The distance of the boat from the shore = 20 meters

The available propulsion devices = A box of apples

According to Newton's third law of motion states that action and reaction are equal and opposite

Therefore, according to Newton's third law, by throwing the apple into the  water in the opposite direction to the shore, such that each apple of mass m₁, is given an acceleration a₁, will result in a force, F₁ = m₁a₁ in the direction away from the shore

According to Newton's third law of motion, the force F₁, will result in an opposite reaction force F₂ in the direction of the shore, such that as F₁ is made large by giving a higher acceleration, a₁ the apples, reaction force on the occupant of the boat , who is throwing the apple, F₂, increases

F₁ = -F₂

Where;

F₂ = m₂·a₂

a₂ = The acceleration of the boat and the occupant

m₂ = The mass of the boat and the occupant

Given that the mass, m₂, is constant, the acceleration of the boat and occupant, a₂, increases as F₁ increases, increasing the speed of the boat from zero to positive value above zero m/s and the boat moves towards the shore

The 2nd note will have a higher frequency or pitch.

Explanation:

The frequency of a standing wave in a string is given by

[tex]f = \frac{ \sqrt{ \frac{t}{ (\frac{m}{l} )} } }{2l} [/tex]

where t = tension of the string

m/l = mass density of the string

l = length of the string

By placing your finger on the string, you increase the tension and at the same time, shorten the length of the string, thereby increasing the frequency of the sound due to the standing wave produced on the string.

Answer:

Building is 747.19 m tall

Explanation:

Given, t

Total velocity v = 123 m/s

Horizontal velocity or the X -component if velocity vx = 22 m/s

For a horizontal projectile motion  

V = Sqrt (vx^2 + g^2t^2)

Or t = sqrt{(v^2 – vx^2)/g^2} ---Eq (1)

Time of flight  

t = sqrt (2h/g) – Eq (2)

where h is the height

Equating, both the equation, we get –  

h = (123^2 – 22^2)/19.6 = 747.19 m

Answer:

A: -2.6 × 10^(-6) C and 2.6 × 10^(-6) C

Explanation:

According to coulombs law, the formula for the force between 2 charged particles is;

F = kq1•q2/r²

Where;

F is Force = |1N|

q1 and q2 are the charges of both particles

k is coulombs constant = 9 × 10^(9) N.m²/C²

r is distance between particles = 0.25

Now, the force |1N| means -1 or +1

Thus;

-1 = 9 × 10^(9) × q1•q2/(0.25)²

Or

1 = 9 × 10^(9) × q1•q2/(0.25)²

Thus;

q1•q2 = -6.94 × 10^(-12)

Or q1•q2 = 6.94 × 10^(-12)

Now, we are told that the magnitude of both charges are the same.

Thus;

q² = 6.94 × 10^(-12)

q = √(6.94 × 10^(-12))

q = 2.6 × 10^(-6) C

Since from earlier, we saw that;

q1•q2 = -6.94 × 10^(-12)

Or q1•q2 = 6.94 × 10^(-12)

Thus means that one of the charges will be negative while the other will be positive.

Thus, the charges are;

-2.6 × 10^(-6) C and 2.6 × 10^(-6) C

Answer:

Explanation:

This is quite tricky! You need to do 2 different equations to solve all the parts of this problem. First is finding the acceleration in one dimension, which has an equation of

F - f = ma

where F is the applied Friction,

f is the frictional force acting against F,

m is the mass of the object, and

a is the acceleration of the object (NOT the velocity!)

This is Newton's Second Law expanded on a bit. The sum of the forces working on an object is equal to the object's mass times its acceleration. We have F, but we need f which is found in the equation

f = μ[tex]F_n[/tex] which is the coefficient of kinetic friction times the weight of the object. Weight is found in the equation

w = mg where m is mass and g is the pull of gravity. Let's start there and work backwards:

w = 37(9.8) to 2 sig figs so

w = 360N. Now fill that in to find f:

f = (.17)(360) to 2 sig figs so

f = 61. Now for the final answer in the original equation way back up at the top:

85 - 61 = 37a and do the subtraction on the left side first:

24 = 37a and then we divide to 2 sig figs to get

a = .65 m/s/s

Since we are moving in a straight line (as opposed to on an angle) the displacement is found in

d = rt which simply says that the distance an object moves is equal to its rate times the time. Therefore,

d = 2.2(3.4) to 2 sig figs so

d = 7.5 m

Given

Mass of bag is [tex]m=8.6\ kg[/tex]

Mass of cart is [tex]M=18.1\ kg[/tex]

bag hits the cart with horizontal speed of [tex]u=5.2\ m/s[/tex]

Suppose the system move with speed v after collision

Conserving the momentum

[tex]\Rightarrow mu+M(0)=(M+m)v\\\\\Rightarrow v=\dfrac{mu}{M+m}\\\\\Rightarrow v=\dfrac{8.6\times 5.2}{18.1+8.6}\\\\\Rightarrow v=1.67\ m/s[/tex]

Answer:

Acceleration is defined as the rate of change of velocity

Explanation:

Its A

Answer: B

Explanation: The higher temperature increases the reaction rate but also favors the reverse read on.

The higher temperature increases the reaction rate, but it also favors the reverse read on. So, option B.

The pace at which the products are created from the reactants in a chemical reaction is referred to as the rate of reaction.

Here,

Generally, reactions progress more quickly as the temperature rises.

The average kinetic energy of the reactant molecules will rise with a rise in temperature. The number of molecules having threshold energy rises, increasing the quantity of efficient collisions that actually occur.

Therefore, as the temperature of the reaction is increased, the rate of the reaction increases. But also favors the reverse reaction.

Hence,

The higher temperature increases the reaction rate, but it also favors the reverse read on.
