The solar system moves at the speed of 828,000 km/h. tara writes the following steps to calculate this speed in decameters/second (dm/s). [1 km = 100 dm] step 1: divide 828,000 by 100. step 2: divide the result obtained in step 1 by 60. step 3: divide the result obtained in step 2 by 60. step 4: write the number obtained in step 3 with the unit dm/s. which step is incorrect in the conversion?

The correct answer is Step 1.  Step 1: Divide 828,000 by 100 is incorrect.

Since Tara wants to convert km to dm, she should multiply by 100.

Conversion factor: 1 km = 100 dm

So the correct step would be as follows:

828,000 km/h x (100 dm/1 km) = 82,800,000 dm/hr

the formula for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .
