|
Answer» Priya is right..... Zalak how u got that ans any derivation is there pls let me know Unit of energy is joule = kg*m²/s²Joule is a MKS unit and erg is a CGS unitMKS = CGS1 m = 100 cm1 s = 1 s1 kg = 1000 gmFrom above :1 joule = 1 kg*m²/s² = 1000 * 10000 / 1 cm*m²/s²= 10^7 gm*cm²/s² = 10^7 ergSo, Answer : 1 joule = 10^7 erg i got this ans by derivation That is wrong. Right answer is 1*10-5(-5 is in power of 10 means 10 to the power of -5) 7 joule 1 × 10^-7 joule i think so this is ans. Verify it once |
