Give the number of significant figures: 92.06 kg significant figures: 0, 3, 4

Hello!

When finding the amount of significant figures in a given value, here are some  conditions.

Non-zero digits are significant (48 = 2 sigfigs) Zeros between non-zero digits are significant (408 = 3 sigfigs)  Zeros before the first non-zero digit are not significant (0.048 = 2 sigfigs) Zeros after a decimal point are always significant (480.0 = 4 sigfigs) Zeros before a decimal point are always significant (480. = 3 sigfigs)

Looking at the given number, we know that non-zero digits are significant, so we have confirmed 3 sigfigs. Also, there is a zero between non-zero digits. So there is an additional significant figure.

Therefore, there are 4 significant figures.

Mass is the amount of matter in an object.  weight is the measurement of the pull of gravity on an object.  say for example, you travel to the moon which has a different gravitational field compared to the gravitational field of earth. (gravitational fields: earth = 1, moon = 0.165)  now when you are on the moon, the pull of gravity on you is different than on the earth. and as weight is the measurement of the pull of gravity on an object, that means yes, your weight can and will change on the moon.  however, on the moon, on earth or even on jupiter, the amount of mass inside of you remains the same. meaning your physical mass remains constant.  in conclusion it is possible for your weight to change as your mass remains constant.
