How does the new moon occur?
Space and AstronomyBottom line: New moon occurs when the moon is on the same side of Earth as the sun. New moons generally can’t be seen. They cross the sky with the sun during the day, and the moon’s shadow side is pointed toward Earth. A new moon is visible only during a solar eclipse. How often
What is the highest point of an orbit called?
Space and AstronomyThe mountain represents the highest point in the orbit. That’s called the apoapsis. The altitude affects the time an orbit takes, called the orbit period. What is the lowest point of an orbit called? The low point of the orbit is called the perigee. The high point of the orbit, when the satellite is moving
Why is a Monomial a polynomial?
Space and AstronomyMonomials include numbers, whole numbers and variables that are multiplied together, and variables that are multiplied together. A polynomial is a sum of monomials where each monomial is called a term. Is a monomial a polynomial? A monomial, or two or more monomials combined by addition or subtraction, is a polynomial. Some polynomials have special
How dense is the Sun’s radiative zone?
Space and AstronomyThe Solar Structure Internal Structure Inner Core Density: 1.622×105 kg/m3 Temp: ~1.57×107 K Radiative Zone Density: 20 g/cm3 to 0.2 g/cm3 Temp: Approx. 7×106 to 2×106 K Convection Zone Surface and Atmosphere Is the radiative zone density? Matter in a radiation zone is so dense that photons can travel only a short distance before they
How water is produced in Mars?
Space and AstronomyHow is water produced in the Mars? Water is produced by burning fuels on Mars. Can water be created on Mars? Breakthrough Invention Makes Water on Mars Useful to Humans, Colonizing Possible. Scientists have recently confirmed that there used to be (and still is) abundant water on Mars. Is water on Mars drinkable? Scientists have
How is a house different from a space station?
Space and AstronomyThe living and working space in the station is larger than a six-bedroom house (and has six sleeping quarters, two bathrooms, a gym, and a 360-degree view bay window). To mitigate the loss of muscle and bone mass in the human body in microgravity, the astronauts work out at least two hours a day. How
What is a three dimensional shape called?
Space and AstronomyA cube, rectangular prism, sphere, cone and cylinder are the basic 3-dimensional shapes we see around us. We can see a cube in a Rubik’s cube and a die, a rectangular prism in a book and a box, a sphere in a globe and a ball, a cone in carrot and an ice cream cone
How do I change dimension style in MicroStation?
Space and AstronomyTo do this; Go to Dimension Styles, select the New Style you are changing the dimensions to and click on the Advanced tab. Expand General > Placement (see image 1 below) Select the Level you wish to retain the dimensions on (if it is in brackets it takes the active settings) Save the Dimension Style.
What events happened after the Big Bang?
Space and AstronomyAs space expanded, the universe cooled and matter formed. One second after the Big Bang, the universe was filled with neutrons, protons, electrons, anti-electrons, photons and neutrinos. During the first three minutes of the universe, the light elements were born during a process known as Big Bang nucleosynthesis. What event happened first after the Big
What is Circumcentre of a circle?
Space and AstronomyWhat is Circumcentre in a circle? The circumcenter is the center/middle point of the circumcircle formed around a polygon. The circumcircle of a polygon is defined as the circle that moves through all of its vertices and the center of that particular circle is termed the circumcenter/circumcentre. What is Circumcentre formula? According to the circumcenter
