Parabolic and they use it because light hits your face (the focal point) and gets reflected in the mirror. The concave, or parabolic, shape of the mirror surface concentrates the light beams, intensifying light as it gets closer to the focal point! :)
Answer: Color is a property of light that depends on wavelength. The color of a transparent object is determined by the wavelength of the light transmitted by it. An opaque object that reflects all wavelengths appears white; one that absorbs all wavelengths appears black.
Explanation:
Answer:
Approximately 53.3 %.
Explanation:
Molar mass of C2H4O2
= 2 * 12.011 + 4 * 1.008 + 2 * 15.999
= 60.052
% oxygen = (31.998* 100) / 60.052 = 53.28 %
