As the moon revolves around the earth, the side that faces the earth is usually just partially illuminated by the sun. the phases of the moon describe how much of the surface appears to be in sunlight. an astronomical measure of phase is given by the fraction f of the lunar disc that is lit. when the angle between the sun, earth, and moon is θ (0 ≤ θ < 360°), then the fraction f is given by the formula below. f = 1 2 (1 − cos(θ)) determine the angles θ that correspond to the following phases.

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!

i would say

part 1: describe the mass and the surface temperature of dwarf stars.

part 2: explain using complete sentences where on the hr diagram you would expect to find a dwarf star based on its physical properties.

part 1: the mass of a dwarf star is very small and the surface temperature of dwarf stars are high and they have the lowest absolute brightness.

part 2: on the hr diagram you would expect to find a dwarf star based on its physical properties at an absolute brightness of -2 to -4

hope this
