A crescent moon is visible in the northern hemisphere, with the crescent shape on the right side of the Moon. This phase is called: - ️️Waxing crescent A lens ___ light to converge at a point - ️️Refracts A magnetic field line pokes through the Sun's photosphere inhibiting convection and cooling that location. What feature is observed in that location on the photosphere? (Also describe how the other features are formed) - ️️Sunspot A mirror ___ light to converge - ️️Reflects ...

Astro 7N Exam 1The force of gravity by the Sun keeps the planet in orbit around it, but how do the planets affect the sun? - correct answer They exert an equally strong pull on the sun, causing it move slightly Newton's First Law - correct answer An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. ex: if the sun suddenly disappeared, the Earth would continue in the direction that it...

ASTRO 7N test 1Newton's first law - correct answer An object at rest, or in motion in a straight line at a constant speed, will remain in that state unless acted upon by a force. (example: If the Sun suddenly disappeared, the Earth would continue in the direction that it was traveling in its orbit at that time.) Newton's second law - correct answer The acceleration of a body due to a force will be in the same direction as the force, with a magnitude inversely proportional to its mass. •...

EAPS 106 Exam 1, Review Questions and answers, rated A+ The earth's four layers and their thicknesses --crust: radius = 6371 km, thiccness = 35 km mantle: radius = 6336 km, thiccness = 2850 km outer core: radius = 3486 km, thiccness = 2270 km inner core: radius = 1216 km, thiccness = 1216 km How did Earth acquire its internal heat? --The process of planet accretion results from lots of collisions, each producing heat. Combined with heat from the decay radioactive elements, the interior...

What two properties of a planet affect the gravity we feel on its surface? - Answer- Mass and radius Two planets have the same radius. If Planet A is 5 times more mass than Planet B, how does gravity differ on the surfaces of the two planets? - Answer- Gravity is 5 times stronger on planet A Say that there were a planet X in our Solar System with a mass 1/4 the mass of Earth and a radius 1/2 the radius of Earth. How will the gravity on its surface compare to the surface gravity of Earth? -...
