Answer:
wavelength = 0.56 × 10⁻² m
Explanation:
Given data:
Frequency of radiation = 5.4 × 10¹⁰ Hz
Wavelength = ?
Solution:
Formula:
speed of light = wavelength × frequency
wavelength = speed of light / frequency
wavelength = 3 × 10⁸ m/s / 5.4 × 10¹⁰ Hz ( Hz= 1/s)
wavelength = 0.56 × 10⁻² m
Answer : The correct option is, (A) 51.1%
Explanation :
Mass percent : It is defined as the mass of the given component present in the total mass of the compound.
Formula used :
First we have to calculate the mass of 
and 
.
Mass of = 18 g/mole
Mass of 
= 7 × 18 g/mole = 126 g/mole
Mass of = 246.47 g/mole
Now put all the given values in the above formula, we get the mass percent of in .
Therefore, the mass percent of in is, 51.1%
Answer: particle in gas have more energy than the particles in a liquid
<h3 />
Explanation: this is because the amount of energy is directly proportional to how random the system is. gaseous molecules are in a more constant random motion than the liquid molecules
Answer:
Earth is heated . . .
Explanation:
Radiation is certain substances moving at the speed of light
