Answer:
1. The frequency of radio wave radiation is X-ray radiation.
2. The speed of radio wave radiation is X-ray radiation.
Explanation:
1. The frequency of radio wave radiation is lower than the frequency of X-ray radiation.
This is because frequency and wavelength are inversely proportional to each other, and so, the higher the wavelength, the lower the frequency and vice versa.
Wavelength and frequency are related by the equation:
c = λf
where c = speed of light, λ = wavelength and f = frequency
2. The speed of radio wave radiation is the same as the speed of X-ray radiation.
X-ray radiation and radio wave radiation are both electromagnetic waves.
All electromagnetic waves have the same speed, which is the speed of light, c =

Answer:
1 gallon = 3.8 liters rounded to the nearest tenth.
Explanation:
1 gallon = 3.785 litres.
We have to round this in to nearest tenths, nearest tenth means number of figures after decimal = 1.
Here last digit is 5 so we have to add 1 to previous digit.
So, 3.785 rounded will become 3.79
For 3.79 the last digit is 9 so we have to add 1 to previous digit.
So, 3.79 rounded will become 3.8
3.785 liters rounded to the nearest tenth is 3.8 liters.
1 gallon = 3.8 liters rounded to the nearest tenth.
