(Multiply or Divide?) both sides of the equation by m II. (Multiply or Divide?) both sides of the equation by h. g= 2.Using the equation I=V/R, to solve for R you should I.(Multiply or Divide) both sides of the equation by R. II.(Multiply or Divide) both sides of the equation by I. R= 3. Using the equation ME = PE + KE, to solve for PE you should I.(Add or Subtract) KE from both sides of the equation. PE = 4. Using the equation KE = ½ mv2, to solve for v you should I.(Multiply or Divide) both sides of the equation by 2. II.(Multiply or Divide) both sides of the equation by m. III. (Square or Take the squareroot) both sides of the equation. v= 5. Using the equation Q = mc∆t, to solve for c you should I.___________________________________________________________________________ II.__________________________________________________________________________ c= 6. Using the equation PE = ½ kx2 to solve for x you should I.___________________________________________________________________________ II. _________________________________________________________________________ III._________________________________________________________________________ x= 7. Using the equation Fg = G (m1m2)/r2 to solve for m2, you should I. __________________________________________________________________________ II. _________________________________________________________________________ III. ________________________________________________________________________ m2 = Unit Conversions Practice Complete the following conversions: 1) Convert 16.7 inches to feet 2) 7) Convert 27 months to fortnights (there are 14 days in a fortnight and ~30 days in a month) 8) Convert 0.09 miles to inches (there are 36 inches in a yard and 1760 yards in a mile) 9) Convert 4.66 centimeters to miles (there are 0.6 miles in a kilometer) Convert 25 yards to feet (there are 3 feet in a yard) 3) Convert 90 centuries to years 4) Convert 84 miles to kilometers (there are 0.6 miles in a kilometer) 5) Convert 4.75 centimeters to meters 6) Convert 48,987 minutes to days Metric Conversions Worksheet 12) 0.75 kg to milligrams 10) Convert 556 degrees Celsius to Kelvins 11) Convert 25 Kelvins to degrees Celsius 19) 23.8 fg to kg 13) 2. 1500 millimeters to km 20) 2.77 kg to mg 14) 3. 2390 g to kg 21) 2.90 cm to terameters 15) 0.52 km to meters 22) 1.08 kg to μg (micrograms) 16) 65 kg to g 23) 9.57 x 10 8̄ mm to nanometers 17) 750 micrograms to g 24) 2.00 L to mL 18) 0.25 megameters to cm 25) 35.28 mL to L
