Why do we use sin and cos in physics?
Space and AstronomyGenerally, it is the angle a line makes with the x-axis, so the sine is always used to find the y coordinate, and the cosine is always used to find the x coordinate. But in physics, we use angles that appear in odd places. What is sine used for in physics? That is indeed the
What is a inverse statement in geometry?
Space and AstronomyThe inverse statement assumes the opposite of each of the original statements and is notated ∼p→∼q (if not p, then not q). The contrapositive statement is a combination of the previous two. What is an inverse statement example? If the statement is true, then the contrapositive is also logically true. If the converse is true,
How do you propagate calla lilies?
Space and AstronomyPropagation of calla lilies can be done two ways – by rhizomes and by seeds. The easiest way is to divide the rhizomes making sure each has roots and eyes attached. Calla lilies make great house plants. They need bright light and a pot that gives them room to grow. Can calla lilies be propagated
What is the relative size of the universe?
Space and AstronomyThe size of the universe refers to the relative size of the universe and entities contained within it. The universe is vast; it has been expanding for almost 13.8 billion years at a considerable fraction of the speed of light, so it is roughly 13 billion light years across. What is the size of the
What does a 3 dimensional shape look like?
Space and AstronomyThe attributes of a three-dimensional figure are faces, edges and vertices. The three dimensions compose the edges of a 3D geometric shape. A cube, rectangular prism, sphere, cone and cylinder are the basic 3-dimensional shapes we see around us. What is a 3 dimensional object? Three Dimensions: The objects around you, the ones you can
How much money does NASA need to get to Mars?

What would a human need to survive on Venus?
Space and AstronomyWhat would you need to survive on Venus? Answer 1: You would need oxygen because Venus atmosphere has none—only CO2 (carbon dioxide. What is needed to survive on Venus? Most astronomers feel that it would be impossible for life to exist on Venus. Today, Venus is a very hostile place. It is a very dry

What is the meaning of and in probability?
Space and AstronomyIn probability, there’s a very important distinction between the words and and or. And means that the outcome has to satisfy both conditions at the same time. Or means that the outcome has to satisfy one condition, or the other condition, or both at the same time. What is the and/or rule in probability? The
How do you explain 3d shapes to kindergarten?
Space and AstronomyIt goes like this, “3D shapes are solid, not flat. They have corners, edges and faces.…3D Shapes Chant Make a sphere for “solid” and then clap hands like you’re collapsing the sphere into a flat circle on “flat.” Point to an imaginary corner (like on a cube, for example) when you say “corners.” What are
