  4. Question 3 a. 283,890 mJ = ______ J b. 345.8 kg = _____ g c. 2.4 cN = _____ N

  5. Question 4 • 45.6 mg = _____ cg • 857 Km = ___ cm • 20 days = _____ seconds

  6. Question 5 • Convert each of the following measurements into the corresponding amount of meters: • A) 42.3 cm • B) 21 km • C) 0.023 mm

  7. Question 6 • Write in scientific notation: • The planet of Saturn has a mass of 568 500 000 000 000 000 000 000 000 kg b. In 1997, 70 294 601 planes either took off or landed at Chicago’s O’Hare airport

  8. Question 7 • Rewrite in Scientific notation • 2,407,000 = • 0.000305 =

  9. Questions 8. Convert 550 mm into the equivalent meter value. 9. Convert 9.73 ks into the equivalent seconds 10. Convert 1year into the equivalent # of minutes

  10. Answer 1A • 304 km x 1000 m / 1km = 304,000 m bigger unit to smaller  multiply by 1000 1000 m = 1 km

  11. Answer 1B 30,634,578 sec / 60 = 510,576 min 510,576 min / 60 = 8509 hours 8509 hours/ 24 = 354.6 days all are smaller units  bigger means divide Could have done all at once 30,634,578 / (60 x 60 x 24)
