Convert each of the following measurements to its equivalent in metres.
A. 1.1cm
B. 76.2 pm
I don't get how to convert :\
1 meter = 100 cm
1.1 / 100 = 0.011 m
But the answer says, its supposed to be : 1.1 * 10^-2m
pico means 10-12 meter
76.2m * (10^12 picometers/meter)
1.1cm*1m/100cm=.011 meter, and in scientific notation,1.1*10^-2 m or in exponential notation, 1.1E-2 meters.
This is really confusing. For number 2, it says that the answer is supposed to be : 76.2 * 10^-11
oops, I erred , I read it as 76m to pm
76.2pm*(10^-12 m/pm)=76.2E-12 m and in scientific notation, 7.62*10^-11 m.
Converting measurements involves using conversion factors. A conversion factor is a ratio that establishes the relationship between two different units of measure. To convert a measurement to its equivalent in meters, you need to identify the appropriate conversion factor and multiply it by the given measurement.
Let's convert each of the measurements step-by-step:
A. 1.1cm:
To convert centimeters (cm) to meters (m), we use the conversion factor: 1m = 100cm.
To convert 1.1cm to meters, you can set up the conversion factor as follows:
1.1 cm * (1m/100cm)
Now, multiply the given measurement by the conversion factor:
1.1 cm * (1m/100cm) = 0.011m
Therefore, 1.1cm is equivalent to 0.011 meters.
B. 76.2 pm:
To convert picometers (pm) to meters (m), we use the conversion factor: 1m = 10^12 pm. (Note: "10^12" means "10 raised to the power of 12")
To convert 76.2 pm to meters, you can set up the conversion factor as follows:
76.2 pm * (1m/10^12 pm)
Now, multiply the given measurement by the conversion factor:
76.2 pm * (1m/10^12 pm) = 7.62 × 10^(-11) m
Therefore, 76.2 pm is equivalent to 7.62 × 10^(-11) meters.
Keep in mind that understanding conversion factors and their proper use is crucial in converting measurements accurately.
