Characteristics of α, β, and γ rays
1 answer:
Answer:
1. it is symbolized as 4/2 He : Alpha rays
2. it has the weakest penetrating power : Alpha rays
3. It is a high-speed electron : beta rays
4. It possesses neither mass nor charge : gamma rays
5. it has the strongest penetrating power : beta rays
6. its is symbolized as 0/-1e : beta rays
7. it is the most massive of all the components: alpha rays
Explanation:
Let us consider the characteristics of each of the given rays.
α rays: These are helium nucleus so are symbolized by
Due to two protons and two neutrons unlike beta and gamma rays these are the most massive and thus have least penetrating power among the three given rays.
β rays: These are actually high speed electrons and are symbolized as . Due to lesser mass than alpha rays they are more penetrating than them however less penetrating than gamma rays.
γ rays : They carry no charge or mass. Due to least massive among the three rays they have highest penetrating power.

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
- 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
