Although the Sun is much larger than the Moon, it does not exert as much gravitational pull
dexar [7]

Answer:

The Sun, just like the Moon and the Earth, also has its own gravity which can affect the tides. Although the Sun is much larger than the Moon and has more gravity, it's also much further away, meaning its pull on the tides is less than half as strong as the Moon's.

What is the product of meiosis I?
Valentin [98]

Answer:

Meiosis I, a reductional division of two haploid cells produces offspring cells that are not genetically identical with the event of recombination. Haploid girl cells have half the original/parent cell chromosomes.

If the blood pressure in your brain is 120 mm when you are lying down, what would it be when you stand up? Assume that your brai
Mashutka [201]

Answer:

The correct answer is 88.84 mmHg.

Explanation:

The pressure differential between the brain and the heart while standing up will be 120 - rho × g (gravity) × h, here h is the distance from the brain to the heart. The h is 40 cm or 0.4 m.  

rho×g×h = 1060 kg/m³×9.8 m/s²×0.4m  

= 4155 Pa  

Now converting Pa to mmHg we get:  

4155 Pa × 760 mmHg / 1.01325 × 10⁵ Pa  

= 31.16 mmHg  

Thus, the pressure in the brain now is 120 - 31.16  

= 88.84 mmHg (hypotension)
