21,600 using only four significant figures is still 21,600.
There are 3 significant figures
273.821 contains 6 significant figures. Rounding that to Hundredths (5 sig. figures) it becomes 273.82 Rounding it to Tenths (4 sig. figures) it becomes 273.8 And Rounding it to the nearest whole number (3 sig. figures) it becomes 274 etc., etc.

Answer: 152.1
A very tiny class of three dimensional figures can be described using only two items of information.
Many simple two-dimensional figures are described using its length and width. Weight only refers to 3D objects as well does volume.
True
A reaction that can be described using a word
There are great advantages and disadvantages to using sales figures. Advantages to using sales figures is to help with projections of sale for future years. The disadvantages of using sales figures is the market is volatile.

145.992 using only four significant figures is 146.0
21,600 using only four significant figures is still 21,600.
All geometric figures.
840 using four significant figures is 840.0
Because otherwise you are using figures which imply an accuracy that cannot be justified.
Yes, alternating currents are a type of simple harmonic motion where the current oscillates back and forth periodically. This motion is characterized by a sinusoidal waveform and can be described using equations similar to those used for simple harmonic motion.
