Solutions containing two substances in the aqueous phase are usually described in volume percentages. Therefore, if a solution has 30% of ethanol, then it has 30% ethanol by volume. The remaining volume is of water, which will be 70%. Calculating:
70% x 100
= 70 ml of water in the solution
Answer:
the oldest rocks are in the center of the dome structure.
Explanation:
Answer:
Wavelength = 9.4×10⁹ m
Explanation:
Given data:
Frequency of radiation = 3.2×10⁻² Hz
Wavelength of radiation = ?
Solution:
Formula:
Speed of light = frequency ×wavelength
Speed of light = 3×10⁸m/s
Now we will put the values in formula.
3×10⁸m/s = 3.2×10⁻² Hz × wavelength
Wavelength = 3×10⁸m/s /3.2×10⁻² s⁻¹
Wavelength = 0.94×10¹⁰ m
Wavelength = 9.4×10⁹ m
