Why can the third stage of a multistage rocket go faster than the first stage?
Space and AstronomyThe third stage of a multistage rocket go faster than the first stage of the rocket, even though it has less fuel because it is already out of the atmosphere and has to travel with less force. Why using multiple stages in a rocket increases the maximum velocity achievable by the rocket? Each successive stage
What is quotient and product in math?
Space and AstronomyPRODUCT – The product of two or more numbers is the result of multiplying these numbers. QUOTIENT – The quotient of two numbers is the result of the division of these numbers. How do you find the product and quotient? Video quote: Two numbers multiplied by each other. So in this case 6 multiplied by
How does Union find work?
Space and AstronomyUnion first uses Find to determine the roots of the trees containing x and y. If the roots are the same, there is nothing more to do. Otherwise, the two trees must be merged. This is done by either setting the parent pointer of x’s root to y’s, or setting the parent pointer of y’s
What are the types of mirrors and lenses?
Space and AstronomyTypes Of Mirrors Plane mirror: The images formed from a plane mirror are the reflected images in their normal proportions but reversed from left to right. … Convex mirror: These are the spherical mirror that is curved outward and the image obtained is virtual, diminished and erect for a real object. Concave mirrors: What are
What’s the edge of the universe?
Space and AstronomyAs far as we can tell, there is no edge to the universe. Space spreads out infinitely in all directions. Furthermore, galaxies fill all of the space through-out the entire infinite universe. This conclusion is reached by logically combining two observations. Where does the universe end? No. The universe is finite but has no end
How do you make a Boolean array in Python?
Space and AstronomyA boolean array can be created manually by using dtype=bool when creating the array. Values other than 0 , None , False or empty strings are considered True. Alternatively, numpy automatically creates a boolean array when comparisons are made between arrays and scalars or between arrays of the same shape. What is a boolean array
What are the 4 different types of angles?
Space and AstronomyAngles: Acute, Obtuse, Straight and Right There are four types of angles depending on their size in degrees. What are the 5 types of angles? In geometry, there are various types of angles, based on measurement. The names of basic angles are Acute angle, Obtuse angle, Right angle, Straight angle, reflex angle and full rotation.
What happens when you add two functions?
Space and AstronomyAdding two functions is like plotting one function and taking the graph of that function as the new x-axis. Points of the second function are then plotted with respect to the new axis. For example, (2, 3) becomes “over 2,” “up 3 from the new axis,” or (3, f + 2). Can you add two
How do you find the slanted part of a triangle?
Space and AstronomyTo find the length of the diagonal (or hypotenuse) of a right triangle, substitute the lengths of the two perpendicular sides into the formula a2 + b2 = c2, where a and b are the lengths of the perpendicular sides and c is the length of the hypotenuse. How do you find the slanted side
Why is Earth called spaceship?
Space and AstronomyHe coined the phrase “Spaceship Earth” to describe our planet. He felt that all human beings were passengers on Spaceship Earth, and, like the crew of a large ship, people had to work together in order to keep the planet functioning properly. Can Earth be called a spaceship? Earth can be called “spaceship” because it
