2016年9月3日 · 120*cm=1.20*m 1*cm = 1xx10^-2*m Thus 120*cm=120xx1xx10^-2*m = 1.20*m. "Centi", "micro", "milli", and "kilo" are simply commonly used mulitpliers to save on the number ...

2018年3月11日 · "400 cm" >>"1 m = 100 cm" "4 m" = 4 cancel"m" × "100 cm"/(1 cancel"m") = "400 cm" ∴ There are 400 centimetres in 4 metres.

2018年5月11日 · The best way to tackle the problem would be to divide the desired amount of cm by how many centimeters are in a meter. #"50 cm"/"100 cm/1 m" = "0.5 m"# If we apply the same concept to your problem:

2016年10月2日 · 5000 cm is a lot greater than 5 meters. Each meter has 100 centimeters and therefore 5 meters are equal to 5xx100=500 cm. Hence 5000 cm is a lot greater than 5 meters.

2017年7月19日 · In short: because there are 10 mm in each cm, the number will go down by a factor of 10 (thus 47.3 mm = 4.73 cm) Similarly in 1 kg there are 1000 g hence 1000 000 mg so the number will increase by a factor of 1 million (2.7356 kg = 2735 600 mg) Fundamentally, you need to understand SI prefixes here and then how to use standard form here and you ...

2017年9月19日 · 1 m= 1000 mm D=0.0179 m Because 1 meter equals 1000 mm or 100 cm.

2016年11月15日 · 1 cm = 10 mm :. "You can multiply the number of centimeters by 10 to obtain the number of millimeters, for instance:" 3.2 cm * (10 mm)/(1 cm) = 32mm

2018年3月18日 · 53.41 "m" First, you need to know how to find the circumference of a circle. Here's the formula: π * 2r = c R is the radius. C is circumference. You have to multiply r by 2 to get the diameter. Here is another formula: π * d = c D is diameter. Anyway, since you've got two formulas, you know how to do it if you have the radius but not the diameter, or just the radius. …

2016年6月8日 · You use Beer's law: \\mathbf(A = epsilonbc), where: A is the absorbance of the solution. This is unitless. epsilon is the extinction coefficient, or molar absorptivity, of the species in solution in "L"/("mol"cdot"cm"). b is the path length of the cuvet. This tends to be "1 cm" for typical UV-Vis spectrometry. c is the known concentration of your solution in "M" or "mol/L". …

2018年2月24日 · A water trough is 6 m long and its cross-section is an isosceles trapezoid which is 100 cm wide at the bottom and 200 cm wide at the top, and the height is 50 cm. The trough is not full. Give an expression for V, the volume of water in the trough in #cm^3#, when the depth of the water is d cm.
