The average wave speed depends on the medium the waves are traveling through. In general, wave speed is proportional to the square root of tension in the medium. If we know the tension, we can calculate the average wave speed by: v = sqrt(T/µ), where T is the tension and µ is the mass per unit length of the medium.
The amplitude of the body is half of the distance covered in one vibration. In this case, the amplitude would be 10cm.
The mechanical advantage of a lever is calculated by dividing the length of the effort arm by the length of the resistance arm. In this case, the MA would be 5 (100cm/20cm).
The volume of the shoebox is calculated by multiplying its height, width, and length. In this case, the volume is 6 cm x 7 cm x 20 cm = 840 cubic cm.
no of course not sheesh like are you dumb??? wow I cant believe people are asking these questions these days
Before dataloggers, there were ticker tape timers. A TTT is a device which makes dots on a piece of paper tape about 1cm across, fifty every second. If the paper is moving through the TTT, these dots are separated out. Measuring the length of (say) ten spaces on the TTT lets us find the average speed because ten spaces took 1/5 of a second and speed = distance/time. Example: length of a 10-space segment of tape = 20cm. Time to make it = 1/5s Speed = distance/time so the tape is passing through the machine at a speed of 20/(1/5) = 20x5 = 100 cm/s. For accelerating bodies, we can cut them into sequential 10-space lengths then stick them on a piece of paper side by side showing how the average speed is changing with time.
The amplitude of the body is half of the distance covered in one vibration. In this case, the amplitude would be 10cm.

The density of an average cat is around 1.0-1.1 g/cm3.
20cmx 20cm x20cm
Thorny devils average less than 20cm in length.
It is 40,000mm
It is 400cm or 4 meters
in inch 20cm = 7.8740 inches thank you!
20cm x 20cm
20cm wide 20cm wide
20cm +20% = 24cm
If you mean how many mm in 20cm then there are 200mm
