Why do radio telescopes have to be very large quizlet?
Space and AstronomyWhy are Radio Telescopes larger than than optical telescopes? Radio wavelengths are much longer thus low energy. Dish must be big enough to to collect enough radio photons. Why do radio telescopes have to be so large? Because radio telescopes operate at much longer wavelengths than do optical telescopes, radio telescopes need to be much

Why are vertical angles equal?
Space and AstronomyAre Vertical Angles Congruent? When two straight lines intersect each other vertical angles are formed. Vertical angles are always congruent and equal. Vertical angles are congruent as the two pairs of non-adjacent angles formed by intersecting two lines superimpose on each other. How do you prove that vertical angles are equal? Video quote: So angle

When can I transplant calla lilies?
Space and Astronomyspringin the spring after all danger of frost has passed and the soil is beginning to warm. Choose a location with organically rich soil that holds moisture well. Callas grow well in low, moist areas where most other rhizomes would suffer from root rot. How do you divide and transplant calla lilies? In late winter

How do you find the dot product of an angle?
Space and AstronomyHow do you find the dot product when given the angle and length? Video quote: Or the angle between two vectors we could find by using cosine theta equals u dot V divided by the magnitude of U. Times the magnitude of V. What does dot product say about angle? If the dot product is

What are the different angles in transversal?
Space and AstronomyThe intersections of a transversal with two lines create various types of pairs of angles: consecutive interior angles, consecutive exterior angles, corresponding angles, and alternate angles. What are the 5 kinds of angles formed by lines cut by a transversal? Intersection caused by transversal forms several angles. These are corresponding angles, alternate interior angles, alternate

Does open circle mean parentheses?
Space and AstronomyIs parenthesis open circle? Intervals are either open or closed or both. Open intervals use parentheses ( ) and refer to intervals that do not include the endpoints. Closed intervals use square or box brackets [ ] and refer to intervals that do include the endpoints. What does an open circle mean? Correct answer: A

Can a system of two linear inequalities only have one solution?
Space and AstronomyA system of linear equations usually has a single solution, but sometimes it can have no solution (parallel lines) or infinite solutions (same line). Can a linear inequality have only one solution? Most of the time, an inequality has more than one or even infinity solutions. For example the inequality: x>3 . The solutions of

How hot is Venus for kids?
Space and AstronomyIt’s the hottest planet in our solar system, even though Mercury is closer to the Sun. Surface temperatures on Venus are about 900 degrees Fahrenheit (475 degrees Celsius) – hot enough to melt lead. The surface is a rusty color and it’s peppered with intensely crunched mountains and thousands of large volcanoes. How hot is

What is solar eclipse in short answer?
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 solar eclipse

What is tidal heating quizlet?
Space and AstronomyTidal heating is caused by a change in tidal forces. Tidal forces stretch out a solar body. However, another solar object pulls on the solar object causing its orbit to be elliptical. The solar system object is further away from the object it is orbiting at times causing the solar system. object to be less
