Question

Young's modulus of steel is 1.9 × 10¹¹ N/m². When expressed
in CGS units of dyne/cm², it will be equal to (1N = 10⁵ dyne,
1 m² = 10⁴ cm²)
(a) 1.9 × 10¹⁰ (b) 1.9 × 10¹¹
(c) 1.9 × 10¹² (d) 1.9 × 10¹³

Answer 1

Answer:

(c) 1.9 × 10¹² dyne / cm²

Step-by-step explanation:

$= > 1.9 \times {10}^{11} \times \frac{ {10}^{5} }{ {10}^{4} }$

$= > 1.9 \times {10}^{11} \times {10}^{1}$

$= > 1.9 \times {10}^{11 + 1}$

$= > 1.9 \times {10}^{12}$

Hope this answer helps you ^_^ !
