Answer:
A film badge
Explanation:
The film badge dosimeter or film badge is a personal dosimeter used for monitoring cumulative radiation dose due to ionizing radiation. It of a photographic film and a holder. This film badge is used to determine or measure and record the radiation exposure as a result of radiations, x-rays, gamma rays and also beta particles.
All users of medical x-ray equipment (C-arms, fluoro units, therapy units) must wear badges. Those using larger quantities of radioactive materials will also be provided badges. The correct option is A.
What is film badge?Ionising radiation exposure is measured using photographic film for personnel monitoring purposes. A filter that protects part of the film from particular types of radiation may also be present in the film badge, which may contain two or three films with varying sensitivity levels.
A particular kind of passive dosimeter is the film badge. It comprises of a photographic emulsion film in a light-tight wrapping (kept in a holder) that changes optical density in response to ionising radiation. The holder, which also includes several filters (for calculating tissue equivalent amounts), is typically worn on the body's trunk.
So film badge is the device used most commonly today for monitoring the radiation exposure of personnel.
Thus the correct option is A.

O rendimento de determinada máquina térmica é de 5%. Sabendo que essa máquina obedece as leis da termodinâmica e que ela recebe da fonte quente 5000J de energia, então o trabalho realizado por essa máquina a cada ciclo é de:
Answers
Answer:
Trabalho realizado por máquina térmica = 250 J
Explanation:
Dado
Eficiência da máquina térmica = 5% = 0,05
A eficiência é igual à proporção do trabalho realizado pela máquina térmica para o calor fornecido a ela
Por isso,
0,05 = Trabalho realizado por máquina térmica / 5000 J
Trabalho realizado por máquina térmica = 5000 J * 0,05 = 250 J

Explanation:
Ionic compounds are said to be formed when metals donate electrons to non metals.
The metals become positively charged while the nonmetals become negatively charged.
CaF2 is composed of Ca^2+ and F^-. Calcium is a metal of group 2 in the periodic table while F is a nonmetal of group 17 in the periodic table.
Hence CaF2 is composed of a metal and a nonmetal.

When crossing parents with genotypes Rr and rr what will be the percentage of the genotypes of the offspring
Answers
Answer:
Explanation:
Heterozygous cross with a hom.ozygous recessive yields the following results
50% rr (hom.ogyzous recessive)
50% Rr (heterozygous dominant)
A heterozygous cross with a homozygous recessive gives the following results: 50% rr (homozygous recessive) and 50% Rr (heterozygous dominant).
What is Parental crossing?Crossing over is a type of cellular process which occurs during the process of meiosis when chromosomes of the same type line up. When these two chromosomes – one from the mother and one from the father – line up, parts of the chromosome can be switched. Two chromosomes contain the same genes, but the genes may have different forms.
The organisms in this initial hybridization are called the parental or P generation. The progeny of the Rr x rr cross are called F1 generation which will have a heterozygous cross with the homozygous recessive giving the following results: 50% Rr (homozygous recessive) and 50% rr (heterozygous dominant)
A cross between two of the offspring in F1 generation would produce a new set of progeny called second filial generation (or F2 generation).
Thus, a heterozygous cross with a homozygous recessive gives the following results: 50% rr (homozygous recessive) and 50% Rr (heterozygous dominant).

Why are polar gases, such as H2O and NH3, more likely to deviate from the ideal gas behaviors described by the kinetic molecular theory? (3 points)
Question 4 options:
1)
The density of these gases is high, increasing the number of collisions and reducing their elasticity.
2)
The fluidity of these gases is high, resulting in a higher average kinetic energy.
3)
The particles have a significant volume, reducing the space between the moving particles.
4)
The particles have high intermolecular forces, reducing the elasticity of their collisions.
Answers
Answer:
HCl, H2O, and NH3 are the most polar of these, so they won't behave ideally because the particles have greater attractive forces between them. How does the kinetic-molecular theory explain the pressure exerted by gases? ... Particles are always in motion and when they are contained, they are elastic collisions.
The particles have high intermolecular forces, reducing the elasticity of their collisions.
What are polar gases?Polar molecules are formed when a high electronegative atom combined with a less electronegative atom.
Ammonia, sulfur dioxide, hydrogen sulfide, are polar gases.
The non-polar gases are inert gas or noble gas.
The polar compounds are asymmetrically array.
Thus, the correct option is 4, The particles have high intermolecular forces, reducing the elasticity of their collisions.
