Most coastal areas on Earth experience two high tides and two low tides every lunar day. What is a lunar day? Our days on Earth
ahrayia [7]

The correct answer is - C) 5:35 PM Friday.

The low tides occur twice in a lunar day, thus they are diurnal. The low tides appear when the Moon is between that point of the planet and the opposite of that point of the planet, thus in between, which is happening twice, on opposite parts of the planet.

Since the lunar day lasts for 24 h 50 m, we should just divide it in two, thus get 12 h 25 m. Than we should add the 12 h 25 to the time when one of the low tides appeared, which is 5:10 AM, so we will get 5:35 PM.

The low tides appear because the Moon is pulling the water upwards with its gravitational pull above the place where it is, so the side parts of the planet have their waters dragged away,thus resulting in the retreating of the water, known as low tide.

Two linebackers tackle a quarterback. One hit him with a force of 105 N and the other hit him with a force of 150 N. They are bo
Setler [38]

The net force on the quarterback when he is hit by two linebackers running eastwards is 255N.

Force is a vector quantity, we must recall that if two forces act in the same direction, we obtain the net force by adding the two forces together. If two forces act in opposite direction, we obtain the net force by subtracting the forces from each other.

Since the both linebackers are running East, the net force is obtained as; 105 N + 150 N = 255 N.

UNO [17]

Answer:

Filip's medical report, diagnosed with Alzhaimer's, may reveal a diminished production of acethylcholine.

Explanation:

Alzhaimer's disease is a neurodegenerative condition that causes immediate memory loss, behavioral changes and cognitive impairment, due to neuronal alterations and atrophy.

The neurotransmitter acetylcholine —related to neuronal transmission and body movement— may experience a decrease in its production leading to Alzheimer's, according to the cholinergic hypothesis.

Many therapies and treatments at present are based on the use of drugs to correct the acetylcholine deficit.

Regarding other options:

  • <em>Dopamine: alteration or deficit is related to Parkinson's disease.</em>
  • <em>Gamma aminobutyric acid (GABA): deficiency is not common and is related to a type of congenital and infantile neuropathy. </em>
  • <em>Serotonin: deficit of this neurotransmitter can lead to depression and psychological disorders.</em>
