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

Explanation:
Terminal atoms -
<u>The atoms that are always present at the terminal position , because they have the capability of bonding via one single bond .</u>
hence ,
- Hydrogen atom is a terminal atom , because it can only form one single bond , since , hydrogen has only one electron in its shell , so the octet is completed by sharing that electron with another one electron , and forming a bond .
Therefore , hydrogen atom is considered to be a terminal atom .
- Similarly , Halogens have 7 electrons , hence , to attain noble gas configuration , it require only one electron .Hence , it can form only one single bond .
Therefore , halogen atom is considered to be a terminal atom .
Answer:
The state of matter of a frozen fruit bar is solid. One property of solids is that they have a fixed shape, because the particles are tightly compressed and cannot move about. Another property is that solids can’t be compressed, because the particles have no space to move as a result of the compression. The frozen fruit bar has no free electrons so, like most other solids, it cannot conduct electricity.
Explanation:
It is 10 times larger. 1 centigram = 10 miligrams, which means that it is 10 times larger.
