The scale model of an airplane is 1:130, where 1 inch on the model is equal to 130 inches on the actual airplane. Which statement about the scale model is true?

• the scale model is larger than the actual plane

• the scale model has the same working parts as the actual plane

• the scale model will perform the same way as the actual plane

• the parts of the model plane are in the same proportion as the actual plane

The table shows the diameters of paper circles used to represent the planets. What is the scale used in the table?

• 1 cm = 1,000 km

• 1 km = 10,000 cm

• 1 cm = 10,000 km

• 1 km = 1,000 ck

• the diameter paper model is proportionally the same size as the diagmeter of planet Earth

• the paper model is the same shape as planet Earth

• the texture of the paper model is the same as the planet earth

How were the planets in the solar system formed?

• the remaining material from the sun's formation clumped together due to gravity

• the solid material were forced out of the sun's disc and cooled down

• the dust particles were attracted by gravity from distant galaxies

• the gas particles released by the sun were pulled away and became solid

What prevents the gravity of the sun to pull all of the planets towards it?

• the size and shape of the planets around the sun

• the large distance of the planets from the sun

• the planets' speed as they orbit the sun

• the sun's weak gravity
