What is the formula for HVL (half-value layer)?

Answers

Answer 1
The half-value layer formula is HVL = = 0.693/μ.
Multiply your answer by 10 to express your HVL in millimeters. This is necessary because many attenuation coefficients are given with the units cm-1, and some HVLs are expressed in mm.

Explanation:

En un supermercado intentan hacer una promoción de frutas de acuerdo a su peso, intentando juntar varias frutas para que en total su peso sume 10 kilogramos y así se pueda vender todo junto a un precio menor. Las frutas del supermercado son famosas por tener un peso casi igual, y se sabe que una sandía pesa 8 kilogramos, una manzana 200 gramos y una pera 170 gramos. En una balanza se sitúan al lado izquierdo 4 manzanas (m), 4 peras (p), 1 sandía (s) y 8 ciruelas (c), mientras que al otro lado se coloca un peso de 10 kilogramos, dando como resultado el equilibrio de la balanza. 1. Siendo así, ¿cuánto pesan en total las ciruelas? ¿podrías decir cuánto pesa cada una? 2. Con estas cuatro frutas, ¿hay más posibilidades de armar la promoción de los 10 kilogramos? ¿Puedes encontrar al menos 4 más?

Answers

Answer:

Cada ciruela pesa 65 gramos, y las 8 ciruelas en total pesan 520 gramos.

Explanation:

Si cada manzana pesa 200 gramos y hay 4 manzanas, su peso total es de 800 gramos (200 x 4). A su vez, si cada pera pesa 170 gramos y hay 4 peras, su peso total es de 680 gramos (170 x 4). Finalmente, hay también 1 sandía, cuyo peso es de 8 kilos. Por ende, el peso de estas frutas en conjunto es de 9.480 kilos.

Ahora bien, dado que también hay en la balanza 8 ciruelas, y que el peso total de las frutas es de 10 kilos, para determinarse el peso de las ciruelas debe realizarse el siguiente cálculo:

10-9.480 = 8 CIRUELAS

0.520 = 8 CIRUELAS

0.520/8 = CIRUELAS

0.065 = CIRUELAS

Así, cada ciruela pesa 65 gramos, y las 8 ciruelas en total pesan 520 gramos.

Based upon what you know what would happen to bone tissue if one of the three types of bone cells were missing but the other types of bone cells were present in the tissue?

Answers

Answer:

My conviction is what would happen to the bone tissue if one pf the three bone cells were missing but the other types of bone cells were present in the tissue is that it would be beneficial to have all four bone cells in the human tissue based on anatomy and celllar organisms such as humans but having only one bone cell in the human tissue would and create a longer time standard to heal if the human goes trough internal bleeding and even external.

Having all four cells would make the tissue stronger and it is imperitive to have many more red and white blood cells to heal the tissue.The bone tissue would still be part of the human body as obvious but in a weaker and more vunerable stage.

What is DNA?

Deoxyribonucleic acid, also known as DNA, is a large molecule that houses our distinct genetic code. The sense strand and the antisense strand are the two strands that are antiparallel to one another and run in the opposite directions, respectively, from 5' to 3' and 3' to 5'.

This double helix structure was first discovered by Francis Crick and James Watson with the help of Rosalind Franklin and Maurice Wilkins.

Long sequences of each of the four bases—A, C, G, and T—make up each strand. The "rungs" of the DNA "ladder" are formed when the bases on one strand of the DNA molecule couple up with complimentary bases on the other strand.

Therefore, DNA can be found in hair, blood, semen and any other body fluid.

mr. wells is trying to understand the difference between Original medicare and Medicare Advantage. What would be the correct description?

Answers

Answer: The correct description is that Medicare Advantage is a way of covering all the Original Medicare benefits through private health insurance companies.

Explanation:

Medicare is a United States health Insurance program. Medicare coverage is a health plan which consists of Medicare advantage and Original Medicare.

Original Medicare: When an individual registers for this, the government pays directly for the health care services received. It's advantage includes:

-- the individual can see a specialist without prior authorization and

-- it is accepted by most doctors in the country,

But it doesn't include prescription drug benefits.

Medicare Advantage: This is a Medicare health plan that allows private health insurance companies to provide Medicare benefits for a registered individual. It offers all the benefits of Original Medicare but with different rules and costs. In addition, it includes prescription drug benefits.

Therefore from the descriptions, Medicare Advantage is a way of covering all the Original Medicare benefits through private health insurance companies.

How can the skull be used to determine age?

Answers

Answer:

Study the skull of the skeleton. Not only does the size of the skull change as we age, the joints or fontanels between the bones change, becoming smaller with age. ... If the skeleton has wisdom teeth, the person was past the age of 18. If there is significant bone loss, it indicates a more advanced age.

Explanation:

The skull can be used to determine age through various methods of cranial analysis.

In forensic anthropology and archaeology, experts examine specific features of the skull, such as cranial sutures and dental development, to estimate the individual's age at the time of death or burial.

The fusion of cranial sutures is particularly useful, as these sutures close over time as a person ages. Dental development and eruption patterns also provide valuable age-related information.

By comparing these features with established age standards and growth charts, anthropologists can estimate an individual's age within a certain range, helping in the identification of unknown individuals or gaining insights into past populations and demographics.
