Given the data, the correct statement is
Even though for a majority of the race they accelerated at the same rate, Beverly won because her initial acceleration was greater than Carl’s
<h3>What is acceleration? </h3>
This is defined as the rate of change of velocity which time. It is expressed as
a = (v – u) / t
Where
- a is the acceleration
- v is the final velocity
- u is the initial velocity
- t is the time
<h3>How to determine the initial acceleration of Beverly</h3>
- Initial velocity (u) = 0 m/s
- Final velocity (v) = 15 m/s
- Time (t) = 10 s
- Initial acceleration (a₁) =?
a₁ = (v – u) / t
a₁ = (15 – 0) / 10
a₁ = 1.5 m/s²
<h3>How to determine the final acceleration of Beverly</h3>
- Initial velocity (u) = 15 m/s
- Final velocity (v) = 35 m/s
- Time (t) = 50 - 10 = 40 s
- Final acceleration (a₂) =?
a₂ = (v – u) / t
a₂ = (35 – 15) / 40
a₂ = 0.5 m/s²
<h3>How to determine the initial acceleration of Carl</h3>
- Initial velocity (u) = 0 m/s
- Final velocity (v) = 10 m/s
- Time (t) = 10 s
- Initial acceleration (a₁) =?
a₁ = (v – u) / t
a₁ = (10 – 0) / 10
a₁ = 1 m/s²
<h3>How to determine the final acceleration of Carl</h3>
- Initial velocity (u) = 10 m/s
- Final velocity (v) = 30 m/s
- Time (t) = 50 - 10 = 40 s
- Final acceleration (a₂) =?
a₂ = (v – u) / t
a₂ = (30 – 10) / 40
a₂ = 0.5 m/s²
SUMMARY
- Initial acceleration of Beverly = 1.5 m/s²
- Final acceleration of Beverly = 0.5 m/s²
- Initial acceleration of Carl = 1 m/s²
- Final acceleration of Carl = 0.5 m/s²
From the above calculations, we can see that Beverly's initial acceleration is higher than that of Carl's and their final acceleration is the same.
Therefore, the correct answer to the question is:
Even though for a majority of the race they accelerated at the same rate, Beverly won because her initial acceleration was greater than Carl’s

Answer:
TRUE!!!!
Explanation:
Water can act as both an acid and a base in solution and undergoes autoionization, where it can be both an acid and a base to itself. When mixed with an acid, water accepts hydrogen ions and acts as a base. However, when water is mixed with a base, it donates hydrogen ions and acts like an acid.

Answer:
- <em><u>Step 2 (the slow step).</u></em>
Explanation:
The rate-determining step is always the slow step of a mechanism.
That is so, because it is the slow step which limits the reaction.
Imaging that for assembling a toy you have process of three steps:
- 1. order ten pieces, which you can do in 1 minute: meaning that you can order order the pieces for 60/1 = 60 toys in 1 hour.
- 2. glue the pieces and hold the toy until the glue hardens, which takes 1 hour: meaning finishingh 1 toy in 1 hour.
- 3. pack the toy, which takes 2 minutes: meaning that you can pack 60/2 = 30 toys in one hour.
The time to glue and hold one toy until the glue hardens determines that you can assemble 1 toy in 1 hour and not 60 toys or 30 toys.
Thus, the step that determines the rate at which the reaction happens is the slowest step: step 2.
This means that the reaction is in dynamic equilibrium.
Hope this helps because I don't really know the question you asked :)))
Answer: 596 atm
Explanation:
Given that,
Original pressure of balloon P1 = 3atm
Original temperature of balloon T1 = 298K
New pressure of balloon P2 = 6atm
New temperature of balloon T2 = ?
Since pressure and temperature are given while volume is constant, apply the formula for Pressure law
P1/T1 = P2/T2
3 atm / 298K = 6 atm / T2
To get the value of T2, cross multiply
3 atm x T2 = 6 atm x 298K
3 atmT2 = 1788 atmK
Divide both sides by 3 atm
3 atmT2 / 3 atm = 1788 atmK / 3 atm
T2 = 596 atm
Thus, a temperature of 596 atmospheres is required to increase the pressure to 6 atm.
