Question

Needs correct number of significant figures.

To demonstrate that you understand the relationship of one metric unit to another, fill in the blanks below. 1.5 mm = um 1,000 nm = 0.25 mm = um Sum 1,500 m = ___ mm 55 nm = um 7.5 m = __ _nm 1.5 cm = mm = 5,000 nm = um = _mm = _cm

Answer 1

that imm= 1000 hm = 103 mm We know 0.25*103 So. 0.25mm = tuo 1.5 X 10% 250NM 1.5 m m = 1500 Hm = 55X10-3 55non and and Inme 0.00 mm inm= - 5510-3 - 103 mm = 0.05 Sum so looonm = 10-3 x 103 mm = IMM and we knolo im = 1000 mm so 1500m- 15ooma 1500x1000 mm - 158105mm 3) ima 109 nm 7.5m= 7x100 nm 1.5cm = 15mm = 15000 lm 15000 nm - 1.5 mm - 0.0015mm = 0.00015 cm
