convert 1joule of energy into erg.
Answers
Answer:
As per the International System of Units, one Joule is equal to the work done on an object upon which a force of one Newton is acting to move the object by one metre in the direction in which the force was applied. The SI unit of energy is named after the English mathematician and physicist James Prescott Joule.
Joule can be defined as the heat energy that gets dissipated when one ampere of electric current passes through one meter of a suitable conductor having a resistance of one ohm
Joule is the SI unit of energy, while erg is the CGS unit of energy.
1 Joule of Energy = 1 Newton x 1 metre
1 erg = 1 dyne x 1 cm
1 joule= 1 newton x 1 metre
1 joule = 105 dynes x 102 cm
1 joule =107 erg
Dimension Formula for Joule is [M¹L²T⁻²]
Let N1(joule) = N2(erg)
N1[M₁¹L₁²T₁⁻²] = N2[M₂¹L₂²T₂⁻²]
N2 = N1[M₁¹L₁²T₁⁻²] /[M₂¹L₂²T₂⁻²]
N1 x [M1/M2]¹ x [L1/L2]² x [T1/T2]⁻²
1 x [1kg/gm]¹ x [1m/1cm]² x [1s/1s]⁻²
1 x (1000g/gm) x (100cm/1cm)² x (1s/1s)⁻²
⇒ 10⁷
N1(joule) = N2(erg)
∴ 1 Joule = 10⁷erg
