What are exoplanets made of?
Space and AstronomyExoplanets are made up of elements similar to that of the planets in our solar system, but their mixes of those elements may differ. Some planets may be dominated by water or ice, while others are dominated by iron or carbon. How are exoplanets formed? Core accretion is the “bottom-up” approach: Large objects form from
How many bit strings of length eight either start with a 1 bit or end with the two bits 00?
Space and Astronomy160Detailed Solution The correct answer is “option 3“. Hence, the number of bit strings of length 8 that will either start with 1 or end with 00 is 160. How many bit strings of length eight either start with a 1 bit or end with the two bits 0 1? Therefore, there are 15 such
What is eclipse of the sun and moon?
Space and AstronomyA solar eclipse occurs when the moon gets between Earth and the sun, and the moon casts a shadow over Earth. A solar eclipse can only take place at the phase of new moon, when the moon passes directly between the sun and Earth and its shadows fall upon Earth’s surface. What is eclipse of
How do you make a parabolic reflector?
Space and AstronomyThe easiest way is to cut and fold a flat sheet into a parabolic dish. Then glue a layer of aluminum foil on its inner surface, for reflectivity. The flat sheet can be as cheap as cardboard. However water resistant material, such as plastic or metal, will last longer. How do you make a parabola
What is algebraic reasoning in high school?
Space and Astronomy“Algebraic reasoning is a process in which students generalize mathematical ideas from a set of particular instances, establish those generalizations through the discourse of argumentation, and express them in increasingly formal and age-appropriate ways.” What year do you take algebraic reasoning? In Algebraic Reasoning, students build on the knowledge and skills for mathematics in Kindergarten-
What was the first US Mars landing?
Space and AstronomyViking 1 landerViking 1 lander, an unmanned U.S. planetary probe, successfully lands on the surface of Mars. Viking 1 was launched on August 20, 1975, and arrived at Mars on June 19, 1976. When did the US first land on Mars? Mars Pathfinder was a U.S. spacecraft that landed a base station with a roving
How do you do the circle dip?
Space and AstronomyHow do you use a circle dip? Expert Answer: Dip circle use to measure the dip angle. To use the dip circle: (follow the given image) (i) Adjust the leveling screw till the base is horizontal and V inside the box is vertical. (ii) Rotate the box B till the ends of magnetic needle NS
Do complementary angles share a common side?
Space and AstronomySupplementary angles are two angles whose sum is 180 degrees while complementary angles are two angles whose sum is 90 degrees. Supplementary and complementary angles do not have to be adjacent (sharing a vertex and side, or next to), but they can be. What angles share a common side? Adjacent angles are any two angles
What type of decimal representation of a number gives us an irrational number?
Space and Astronomynon-terminating decimalsnon-terminating decimals with non-repeating digits. Non-terminating, Non-repeating decimal expansion means that although the decimal representation has an infinite number of digits, there is no pattern to it. What type of decimal is an irrational number represent? When an irrational number is changed into a decimal, the resulting number is a nonterminating, nonrecurring decimal. Therefore,
How much would a manned mission to Mars cost?
Space and AstronomyNASA’s Perseverance rover has become the latest to touch down safely on the red planet. The mission is expected to cost $2.7 billion, rising to $2.9 billion when inflation is factored in. How much would a human Mars mission cost? $20 billion The mission would take about 440 days to complete, with three astronauts visiting
