Help PLEASE!!!
To what does “SI” refer in physical science? A. an international system of standard units for physical quantities B. a Greek letter that stands for one of the fundamental quantities C. the speed of light in a vacuum D. a magazine called Science Illustrated

SI refers to international system of units of physical quantities
tHANK YOU SOO MUCH!
np
I have other question
yes
Any physical quantity can be expressed in terms of seven fundamental base quantities. A. True B. False
True tke example of unit of force Newton. Newton can be written as \(kgm/s^2\)
thank you
Suppose you and three friends each measured the width of a desk with a meter stick to see if the desk could fit through a door without tilting the desk. Your measurements were 0.7620 m, 0.7611 m, 0.7625 m, and 0.7525 m. Suppose that the meter stick is a good one. Suppose also that you and your friends have learned to measure well, but recognize that people sometimes make mistakes. What might you infer from the measurements? Check all that apply. A. One of the measurements appear to be inaccurate by about 0.01 m. B. The accuracy of careful measurements with the meter stick appears to be no better than within 0.01 m. C. This ruler enables measurements that are precise to at least thousandths of a meter.
@jiteshmeghwal9
C should be the answer u may guess the least count of measuring device from the measuremens
Are you sure there isn't any other answer?
Because you can chose more then one...
yeaah A should also be correct 3 measurements are about 0.76 & one measurement is about 0.75 so one of the measurement appears to be inaccurate about 0.01
Ok, thanks... I have another question too :) That's the last one
For the measurement 0.7620 m, what would be the appropriate expression in scientific notation? A. 0.07620 x 10 m B. 0.7620 m C. 7.620 x 10-1 m D. 76.20 x 10-2 m
c 0.7620=7620*10^-4=7.620*10^-1
THANK YOU SOOO MUCH!!!
I will tell you my result... Just a second.
OMG THANK YOU SOOO MUCH 100 %
Systeme International - Somewhere in France, europe there's a load of people who do/did a lot of science and engineering. That area is also home to CERN which in turn is home to a whacking great big tunnel which contains a "Large hadron collider", LHC, which basically tries to bang atomic particles into each other at very nearly the speed of light - and then watch the mess on various computers. Vive La France, et La Suisse, et Geneve Bon voyage at vous, et bon chance http://perendis.webs.com
ps it's INTERNATIONALE because it's french
