A.7.2. apply (appendix a pp. 878).
a1. convert the values on the left to the units at right, using a table of conversions. a. 50 miles =? km b. 15 knots = ? m s–1 c. 30 lb in–2 =? kpa d. 5000 kw =? horsepower e. 150 lbmass =? kg f. 150 lbforce =? n g. 12 ft = ? m h. 50 km h–1 = ? m s–1

a) 80 km

b) 7.65 m/s

c) 206.7 kPa

d) 6700 horsepower

e) 67.3 kg

f) 666 N

g) 3.6 m

h) 13.88 m/s

Explanation:

a. we know that 1 mile = 1.6 km

b. we know that 1 knot = 0.51 m/s

c. we knwo that 1 lb/inch^2 = 6.89 kPa

d. we know that 1 kilowatt = 1.34 horsepower

e. we know that 1 lbMass = 0.45 kg

f. we know that 1 lbForce = 4.44 N

g.  we know that 1 ft = 0.3 m

h. we know that 1 km/h = 0.27 m/s

a. it led to stricter immigration laws.
