What is the density of water in kgdm–3 if its density in gcm–3 is 0.863?
To convert the density of water from g/cm3 to kg/dm3,we have
1 g/cm3 = 1 kg/dm3
Given that the density of water in g/cm3 is 0.863,so its density in kg/dm3 is also 0.863.
Therefore, the correct option is (B) 0.863
The ratio of the power of a light source \( S_1 \) to that of the light source \( S_2 \) is 2. \( S_1 \) is emitting \( 2 \times 10^{15} \) photons per second at 600 nm. If the wavelength of the source \( S_2 \) is 300 nm, then the number of photons per second emitted by \( S_2 \) is ________________ \( \times 10^{14} \).
