Find the value of 10watt in a new system of units which has 10cm, 100g and 30sec as the fundamental units
Answers
Answer:
Explanation:
Fundamental units = 30 seconds, 10cm and 100g
Energy = (1/2)mv²
Thus, E is directly proportional to mv²
E = 10 J = 10 Kg (m/s)²
10 J = 10 Kg (m/s)²
= 10 x 1000 g x (100 cm /s)²
= 10 x 10 x (100g) x (10 x 10 cm / s)²
= 100 x (100g) x (10 x 30 x 10cm/30s)²
= 100 x (100g) x (300 x 10cm/30s)²
= 100 x (300)² x (100g) (10cm/30s)²
= 9000000 x 100g (10 cm / 30s)²
= 9 × 10`6
Thus, the value of 10watts is 9 × 10`6 new unit.
Answer:

Explanation:
Fundamental units = 30 seconds, 10cm and 100g
Energy = (1/2)mv²
Thus, E is directly proportional to mv²
E = 10 J = 10 Kg (m/s)²
10 J = 10 Kg (m/s)²
= 10 x 1000 g x (100 cm /s)²
= 10 x 10 x (100g) x (10 x 10 cm / s)²
= 100 x (100g) x (10 x 30 x 10cm/30s)²
= 100 x (100g) x (300 x 10cm/30s)²
= 100 x (300)² x (100g) (10cm/30s)²
= 9000000 x 100g (10 cm / 30s)²
= 9 × 10`6
Thus, the value of 10watts is 9 × 10`6 new unit.
