Question

A piece of ribbon is kept on the ruler as shown below. Find out the length of ribbon
and represent it in terms of centimeter and meter.​

Answer 1

Answer:

The harmonic method of analysis and prediction of tides initiated by Lord

Kelvin quickly established itself as necessary and invaluable in areas where the

diurnal tides were comparable in magnitude with the semidiurnal tides, and where,

also, these tidal oscillations were of the deep-water type in which there were no

oscillations associated with the product terms in the equations of motion. But when

the method was applied to tides in the waters surrounding the British Isles it was

found to be much less accurate than the results obtained from the older non-harmonic

included. These are the main shallow water constituents which are of importance

only when the tidal amplitude is not small compared with the mean depth of the

sea or channel. Even to this day the tides for many of the ports overseas are still

predicted by the non-harmonic methods because of the failure of the direct harmonic

method.

Answer 2

Answer:

Given : A piece of ribbon is kept on the ruler as shown  

To Find :  length of ribbon  in cm and m

Solution:

Ribbon one end is at 2cm

Ribbon another end is at 12 cm

Length of Ribbon = 12 - 2 = 10 cm

Length of Ribbon  = 10 cm

100 cm = 1m

=> 1 cm = 1/100 m

=> 10 cm = 10/100 m

=> 10 cm = 1/10 m

=> 10 cm = 0.1 m

Length of Ribbon  =  0.1 m
