Answer:
Both physics and biology
Explanation:
In international space station collection of experiments are performs under various circumstances to study Earth orbit. These experiments belongs to astronomy, meteorology, space science, space medicine, physical science, life science, human research.
Astronomy: It is a branch of science that deals with celestial bodies and its performance. Astronomy deals with concept of physics, chemistry and mathematics for explanation of the phenomenon based on celestial bodies. Physics is used for explanation of their position. Chemistry is used for explanation of structure. Mathematics is used in calculation.
Meteorology: It is a branch of science that deals with the atmospheric condition around earth surface. This is generally used ti telecast whether condition around various places on earth. This uses atmospheric physics and atmospheric chemistry.
Physical science: It is a branch of physics that deals natural science and study of non living things. It uses concept related to physics and chemistry.
Space science: It deals with space exploring and its natural phenomenon in science. This uses atmospheric physics, general physics, general chemistry and atmospheric chemistry.
Space medicine: It deals with medicines of astronauts. It uses concept and study under Biology.
Life science: It is a branch of physics that deals with study of life and organism. It uses concept and study under Biology.
Thus, Answer is both physics and biology.
Answer:
R: 27 u
ou 27g/mol
Explanation:
A massa atômica de um elemento é dada pela soma do número atômico (número de protons) com o número de neutrons. Assim:
A= 13+14 = 27
let the vector Q is given as
given that
here we know that
now by above equation
so by comparing both sides
b = 0
4c - 3a = 6
also we know that
by solving above equation
a = 12.85 and c = 11.14
so the vector Q is given as
Answer:
Option B
Explanation:
Magnification of Microscope is
Mo= Magnification of objective lens and
Me= magnification of the eyepiece.
Both magnifications( of objective and eyepiece) are inversely proportional to the focal length.
Magnification,
when the focal length is less magnification will be high and when the magnification is the low focal length of the microscope will be more.
Thus. Magnification will increase by decreasing the focal length.
The correct answer is Option B
