Page 1: The diagram below represents the path of the Earth’s orbit around the sun compared to the path of the orbit of a comet around the sun. Which statement

The diagram represents the spectral lines from the light of an element in a laboratory on Earth.

Which diagram best represents the pattern of spectral lines from the same element when observed in the light

of a distant galaxy?

Page 2: The diagram below represents the path of the Earth’s orbit around the sun compared to the path of the orbit of a comet around the sun. Which statement

Which planet has the most eccentric orbit?

Mercury!

HOW DO YOU KNOW!

Page 4: The diagram below represents the path of the Earth’s orbit around the sun compared to the path of the orbit of a comet around the sun. Which statement

The diagram below represents the path of the Earth’s orbit around the sun compared to the path of the orbit of a comet around the sun.

Which statement concerning the diagram is probably true?

(1) A comet has a less eccentric orbit and a shorter period of revolution than the Earth.

(2) A comet has a more eccentric orbit and a shorter period of revolution than the Earth.

(3) A comet has a less eccentric orbit and a longer period of revolution than the Earth.

(4) A comet has a more eccentric orbit and a longer period of revolution than the Earth.

How do we calculate eccentricity?

Which planet in the solar system has the most eccentric orbit?

Which planet’s orbit is most circular?

NOTICE IT’S ALWAYS TO A THOUSANDTH!!!!

Mercury = .206

Venus = .007

Page 7: The diagram below represents the path of the Earth’s orbit around the sun compared to the path of the orbit of a comet around the sun. Which statement

E = d/l

d = 1.4 cm

l = 4.0 cmE = 1.4 cm/4.0 cm

E = 0.35 = 0.350

f1 f2

The diagram represents a moon in

revolution /orbit around a planet.

Where will the planet be located?

At one of the foci.

P

State one fact about this moon at its current position

Gravity is weakest, orbit is slowest, distance is greatest, moon appears

smallest, etc.
