Their is going to be 4 sig figs
Answer:
Frequency is of light depends upon the body that emits it. While wavelength depends on the medium through which it travels in vacuum the product of wavelength and frequency is the same while in other mediums the light of higher wavelength travels faster besed on refractive index. So light velocity depends on both frequency and wavelength.
Explanation:
Electron is a fundamental Particle by JJ Thomson so it was truly difficult to say that electron is a negative charge
Answer:
The gas pressure is: 1.55 atm.
Explanation:
We need to use the equation that relate the variables given at the exercise (pressure, temperature and volume) from the ideal gas law formula, when the mass is constant we can reduce the expretion 
to 
solving to P2 we get:
replace the values 
.
