Answer:

4-6 millimeters

Explanation:

Global warming is causing devastating consequences for the planet such as rising sea levels and temperature in the oceans.

The melting of glaciers is one of the main causes of sea level rise.

Undoubtedly, the most affected and vulnerable areas correspond to areas of Asia, Africa and South America. Specifically, the study highlights that in six Asian countries such as China, Bangladesh, India, Vietnam, Indonesia and Thailand, there are approximately 237 million people who will suffer these floods if defense mechanisms are not activated.

The pressure exerted by a column of liquid is equal to the product of the height of the column times the gravitational constant
almond37 [142]

Answer:

The column of methanol is = 12.27 m high

Explanation:

The pressure of mercury  (p) = ghd,................... equation 1

Where g = acceleration due to gravity, h= height, d = density.

d = 13.6 g/ml convert to kg/m³ = 13.6 g/ml(1000 (kg/m³)/(g/ml))

d =13600 kg/m³., h= 713mm = 713/1000 = 0.713 m., g= 9.80 m/s²

Substituting these values into equation 1,

P = 13600 × 0.713 × 9.8 = 95028.64 N/m².

If the pressure of the mercury supports the pressure exerted by the methanol

∴ pressure that supports the mercury = pressure of the methanol

       p = ghd

making h the subject of formula,

h = p/gd ........................... equation 2

Where p = 95028.64 N/m², g = 9.8 m/s², d = 0.79 g/ml = (0.79 × 1000) kg/m³

d = 790 kg/m³.

Substituting these values into equation 2

h = 95028.64/(9.8×790)

h = 95028.64/7742

h = 12.27 m.

The column of methanol is = 12.27 m high

Near the surface of Earth, what is the acceleration of an object due to the force of gravity? !!!!! Please answer !!!!!
Ierofanga [76]

Answer:

Weight. Recall that the acceleration of a free-falling object near Earth's surface is approximately g=9.80m/s2 g = 9.80 m/s 2 . The force causing this acceleration is called the weight of the object, and from Newton's second law, it has the value mg.

Who discovered laws of gravity and motion? He discovered aspects of light and color, leading to today's spectrum analysis
Vitek1552 [10]

Answer:

Sir Isaac Newton

Explanation:

The laws according to which bodies move and how one body attracts another body were developed by Newton. The three laws of motion and the law of universal gravitation were developed by Newton.

In the seventeenth century almost all the refracting telescopes exhibited color distortion. Newton believed that white light had a spectrum which was the reason for this distortion. The lens of a refracting telescope used to act like a prism which caused the dispersion of light proving Newton's hypothesis.
