(Solved) Find the value of 60 J/min on a system that has 100gm, 100cm and 1 min as the base unit.

Question :

Find the value of 60 J/min on a system that has 100gm, 100cm and 1 min as the base unit.

Solution :

In question it is asked to convert value of 60 J/min in another base unit. 

First of all minute is replaced by 60 seconds (Because 1 minute = 60 seconds). 

So new value is 1 J/sec. 

Now Joule is unit of energy and second is unit of time. Energy/time is power. 

Unit of joule is kg*m²/s²

So new value is 1 kg*m²/s³. 

Here  kg*m²/s³ is unit of power. 

Then kg is converted into gram, meter is converted into cm and second is converted into minute. 

After simplification, we get 60 J/min = 2160000 in new unit. 
Answer : 2160000 New unit

Question 2 :

Find the value of 60 J/min on a system that has 100gm, 100cm and 2 min as the base unit:

A) 17.28 × 10^5 

B) 17.28 × 10^6

C) 17.28 × 10^3 

D) 17.28 × 10^4

Solution :

In question it is asked to convert value of 60 J/min in another base unit. 

First of all minute is replaced by 120 seconds (Because 2 minute = 120 seconds). 

So new value is 1 J/sec. 

Now Joule is unit of energy and second is unit of time. Energy/time is power. 

Unit of joule is kg*m²/s²

So new value is 1 kg*m²/s³. 

Here  kg*m²/s³ is unit of power. 

Then kg is converted into gram, meter is converted into cm and second is converted into minute. 

Answer : (B) 17.28 * 10^6 unit
