00:00Proof that 1 Joule is equal to 10 raised to power 7 Erg is 1 Joule is equal to 1 Newton
00:20into 1 meter.
00:25As we know that 1 Newton is equal to 10 raised to power 5 Dyn and 1 meter is equal to 10
00:39raised to power 2 centimeter.
00:44So by putting these values 1 Joule will be equal to the value of 1 Newton is 10 raised
00:56to power 5 Dyn into the value of 1 meter is 10 raised to power 2 centimeter.
01:08So 1 Joule will be equal to when the bases are same then we will add the powers.
01:18So it will be 10 raised to power 5 plus 2 Dyn into centimeter.
01:27So 1 Joule will be equal to 10 raised to power 7 is Dyn into centimeter is equal to Erg.
01:40So 1 Joule is equal to 10 raised to power 7 Erg or 1 Erg is equal to 10 raised to power
01:56minus 7 Joule.
