GIZMOS STUDENT EXPLORATION THE BIG BANG THEORY MATHS CALCULATION WITH REFERENCING QUESTIONS AND ANSWERS EXAM The distance between Earth and Mars is 225 million km. When converted using the conversion factor 1 AU = 1.5 × 108 km, the distance between the planets is [0.2 AU/1.5 AU/2.0 AU]. The astronomical unit (AU) is [shorter than/longer than/the same as] a lightyear. - 1.5 AU SHORTER THAN Drag each tile to the correct location. A scientist is studying the light emitted by several celestial objects. He records the shifts in each object's spectral lines (in nm). Based on these measurements, determine whether each object is moving TOWARD or AWAY from Earth. Use the LINK for the diagram of the visible light spectrum to help you. 400 nm shifted to 430 nm 610 nm shifted to 580 nm 512 nm shifted to 480 nm 670 nm shifted to 690 nm - TOWARD:610 nm shifted to 580 nm AND 512 nm shifted to 480 nm AWAY:400 nm shifted to 430 nm AND 670 nm shifted to 690 nm Match the tools with the advantages they offer to astronomers. photography space telescope radio telescope optical telescope detects electromagnetic frequencies outside the visible spectrum that reaches Earth captures images that can be shared and compared by scientists obtains a magnified and clear view of a part of the sky to observe celestial objects allows access to images taken from outsideEarth's atmosphere - SPACE TELESCOPE:allows access to images taken from outsideEarth's atmosphere PHOTOGRAPHY:captures images that can be shared and compared by scientists OPTICAL TELESCOPE:obtains a magnified and clear view of a part of the sky to observe celestial objects RADIO TELESCOPE:detects electromagnetic frequencies outside the visible spectrum that reaches Earth Arrange the events of the big bang in sequential order. The first neutral atoms form. The universe is transparent. Atomic nuclei form. Hydrogen fuses into helium. The universe comes into existence as a single point. Gases form that will later go on to shape the stars and galaxies. The universe begins expanding, and nuclear forces develop. - The universe comes into existence as a single point. --> The universe begins expanding, and nuclear forces develop. -->Atomic nuclei form. Hydrogen fuses into helium. --> The first neutral atoms form. The universe is transparent. --> Gases form that will later go on to shape the stars and galaxies. Match the events related to the formation of the universe with the stages during which they occurred. The first neutral atoms begin to form. Hydrogen fuses into helium. Expansion from an infinitely hot point. - (left to right on picture) Expansion from an infinitely hot point. Hydrogen fuses into helium. The first neutral atoms begin to form.

A radio telescope detects microwave radiation in space. D. Distant galaxies move progressively farther away from Earth. - B. Scientists discover that 99% of the universe's mass is hydrogen. Which observational tool helped astronomers Arno Penzias and Robert Wilson discover the existence of the cosmic microwave background (CMB)? A. optical telescope B. radio telescope C. a digital camera D. space telescope - B. radio telescope Which occurrence would contradict the big bang theory? A. Over time, distant galaxies move progressively closer to Earth. B. A scientist discovers a black hole outside the Milky Way galaxy. C. The average temperature of the universe decreases. D. A scientist discovers a planet that is about 10 million years old. - A. Over time, distant galaxies move progressively closer to Earth. Venus is an average distance of 108.2 million kilometers from the Sun. Use the conversion factor 1 AU = 1.5 × 108 km to convert this distance from kilometers to astronomical units. Choose the closest answer. A. 0.72 AU B. 1.25 AU C. 3.56 AU D. 45.63 AU E. 96.12 AU - A. 0.72 AU How do dying stars contribute to the formation of planets? A.
