Gamma decay cannot result in the transmutation of the parent nucleus. Therefore, option (A) is correct.
What is Gamma Decay?Gamma decay can be described as the emission of electromagnetic radiation of a high frequency that is a high energy, giving out excess energy to stabilize the unstable nucleus. Gamma rays can be defined as a stream of high-energy radiation given off by a nucleus undergoing radioactive decay.
Gamma decay can be described as the nucleus dropping from a higher energy level to a lower energy level through the emission of high-energy photons.
Therefore, the gamma-ray emitted is also of very high energy, just like x-rays. Due to their high energy of gamma rays, they are penetrating and thereby dangerous to biological life forms.
In the transmutation of an element, one element is converted into another element. In gamma decay, the transmutation of the parent nucleus does not take place. As the gamma-ray high-energy particles are represented as ⁰γ₀.

Un atleta tiene en un instante dado una velocidad de 4 m/s. Si a partir de ese instante y durante 2 s adquiere un MRUA con una aceleración de 3 m/s2. Calcula la velocidad que alcanza al cabo de esos 2 s.
Answer:
Velocidad final, V = 8 m/s
Explanation:
Dados los siguientes datos;
Velocidad inicial, u = 4 m/s
Aceleración, a = 2 m/s²
Tiempo, t = 2 segundos
Para encontrar la velocidad final (v), usaríamos la primera ecuación de movimiento;
V = u + at
Sustituyendo en la fórmula, tenemos;
V = 4 + 2*2
V = 4 + 4
Velocidad final, V = 8 m/s
Light waves Group of answer choices are not electromagnetic radiation. do not require a medium. can not travel in a vacuum. do not travel in straight lines from the source.
Answer:
do not require a medium
Explanation:
Light waves can be regarded as electromagnetic waves and it transverse in nature, no medium material is required to pass through. Light wave can travel through vacuum and it's ray can travel in straight lines even from point source. Light convey energy in perpendicular direction to electric field as well as magnetic field.

El diámetro del embolo de una jeringa para inyección mide 1.5 cm. Una enfermera ejerce una fuerza de 2N cuando inyecta a su paciente. Calcule la presión que ejerce el fluido inyectado sobre las venas.
Answer:
Presión = 11111,11 N/m
Explanation:
Dados los siguientes datos;
Diámetro = 1,5 cm a metros = 1,5 / 100 = 0,015 m
Fuerza = 2N
Para encontrar la presión;
En primer lugar, determinaríamos el área del círculo usando la fórmula;
Área del círculo = πr²
Radio = diámetro/2 = 0.015/2 = 0.0075 m
Área de la jeringa = 3.142 * 0.0075²
Área de la jeringa = 3.142 * 0.00005625
Área de la jeringa = 0.00018 metros
Ahora, podemos encontrar la presión usando la fórmula;
Presión = fuerza/área
Presión = 2/0.00018
Presión = 11111,11 N/m
does frequency of the sound affect speed of sound
Answer:
One of the more important properties of sound is that its speed is nearly independent of frequency. ... Therefore, the relationship between f and λ is inverse: The higher the frequency, the shorter the wavelength of a sound wave. The speed of sound can change when sound travels from one medium to another.

A glass falls from a table top and smashes on the floor 0.6 seconds later. How high is the table?
Equations that can be used
Vv=gt, dv=1/2gt^2, t=2d/g.
Answer:
1.8 m
Explanation:
Given: Glass falls from a table, smashes 0.6 seconds later
To find: How high a table is
Formula: Vv=gt, dv=1/2gt^2, t=2d/g
Solution: A table's height is measured from the top of the edge down to the floor. The tables are shown both have a height of 30 inches, which is common for many tables.

The ratio of the speed of light in a medium to the speed of light in a vacuum
is called its:
A. angle of incidence
B. Snell's Law
C. angle of refraction
D. refractive index
Answer:D.Refractive Indez
Explanation:
It is usually expressed the other way: the ratio of the speed of light in a vacuum to the speed of light in a medium. In that case, it is called the "index of refraction".
You're going for "refractive index", but you've got the ratio flipped over.

Answer:
By the help of magnetic field of the earth

Why does steam at 100°c give severe burn than water at 100 c?
Explanation:
Steam will produce more severe burns than boiling of water because steam has more heat energy than water due to its latent heat of vaporisation and additionally latent heat of condensation. Steam and boiling water can exist at varing temperature but it is only correct to assume here that both are at same temperature.

HOW TO ANSWER THIS QUESTION PLEASE
Answer:
radioactive decay is a random processuse long tongsExplanation:
Quantum theory has taught us that virtually everything to do with the nature of matter in the universe is a random process. The decay of atomic nuclei is something that makes that randomness "visible" with appropriate instrumentation. As such, the rate of decay will vary over the "short" term. Consequently, it is not surprising to see a variation of a few counts in an activity measurement over a period of a few minutes.
__
Safety with respect to radioactive materials involves staying as far away from them as possible. The use of long tongs for handling would be appropriate.
Answer:
Radioactive decay is a long proxyUse long tongs↔ for safety precautions the scientist should used this upon working with radioactive materials in a laboratory.
A high diver dives off a platform and strikes the water 1.857 seconds later. Ignoring air resistance, how fast is he traveling as he strikes the water in m/s?
Answer:
The (vertical) speed of the driver as he strikes the water is approximately 18.22 m/s
Explanation:
From the parameters given in the question, we have;
The time after which the driver strikes the water after he drives off a platform, t = 1.857 s
Let 'v' represent the vertical speed of the driver
We can find the vertical speed of the vehicle as it strikes the water as follows;
v = u + g·t
Where;
v = The final vertical velocity of the driver
u = The initial vertical speed of the driver = 0 m/s
g = The acceleration due to gravity ≈ 9.81 m/s²
t = The time of motion = 1.857 seconds
Therefore, we have;
v = 0 + 9.81 m/s² × 1.857 s = 18.21717 m/s
Therefore;
The vertical speed of the driver as he strikes the water, v ≈ 18.22 m/s
