If the first low tide occurs at 5:10 a.m. on Friday when will the next low tide occur​
jonny [76]

The correct answer is - 5:35 PM on Friday.

The low tides, as well as the high tides, occur two times in a lunar day, on exactly every half a lunar day passed. A lunar day is 24 hours and 50 minutes long, so every next low tide, or high tide, appears after 12 hours and 25 minutes after the previous one. In this situation we have a low tide that has appeared at 5:10 AM on Friday, so in order to calculate when the other low tide will appear we need to add 12 hours and 25 minutes on it, and that will gives the information that the next low tide will appear at 5:35 PM on Friday.

A type of a balanced stretch involves targeting a specific muscle group. When stretching, a person should be aware of the agonist and antagonist muscles being stretched in able to create a balance between the joints where the muscles are attached. Stretching is an important phase in the exercise cycle and should not be missed as this prevents injuries in the joints and increases the blood flow into the muscles that were used during the activity. Stretching also contributes to lessening the lactic acid build up that happens during physical activity.</span>

Question 12 of 20 :
daser333 [38]
A; Carbon’s atomic number is 6, atomic number indicates the amount of protons in an atom. The number of protons (positively charged particles) is equal to the number of electrons (negatively charged particles). Because atoms have a neutral charge. The average atomic mass of carbon is 12.011; this is the amount of protons plus the amount of neutrons because electrons are so small they weigh almost nothing compared to protons and neutrons. To find the number of neutrons you subtract the number of protons from the average atomic mass. 12.011-6=6.011 (which can just be rounded to 6). So a carbon atom has 6 neutrons. Answer A is correct because it correctly states that an atom of carbon has 6 protons 6 neutrons and 6 electrons
