Answer:

the two balls will hit the ground at the same time.

Explanation:

The time of dropping, in the following equation, is related to both the distance travel s and the gravitational acceleration g, which are the same for both ball (if we neglect air resistance), no matter what their mass are.

s = gt^2/2

t^2 = 2s/g

So the time it takes to drop 2 balls are the same. They will hit the ground at the same time.

The relationship between body mass body weight and body density
nordsb [41]

Answer:

The formula for calculating Density is:

= Mass / Volume

From this formula, we can say that the relationship between Mass and Density is a direct one. In other words, if mass is increasing - all else being equal - then density will increase as well.

If mass however was decreasing, density would have to decrease as well.

For example, assume 3 bricks have masses of 5kg, 10kg and 15kg. Also assume that the bricks all have the same volume of 5 m³.

Density of 5kg brick = 5 / 5 = 1 kg/m³

Density of 10kg brick = 10 / 5 = 2kg / m³

Density of 15kg brick = 15 / 5 = 3 kg /m³

<em>Notice how density increases as mass increases and decreases when mass decreases. </em>

What statement is true about the part of the electromagnetic spectrum that is visible to the human eye?
Alja [10]
Based on the options above, I see how the last option would actually be most fitting to how "the part of the electromagnetic spectrum that is visible to the human eye". This would be in separate parts, which would be divided into a certain number, which would actually be only 7 ranges of wavelengths. And therefore, this last statement would actually go very well and it would actually be the correct answer. And this would all relate to how <span> the part of the electromagnetic spectrum that is visible to the human eye, it's based on it's own 7 division parts that it has. 

Your answer: </span>\textsf{It is divided into seven ranges of wavelengths}

On planet X, the absolute pressure at a depth of 2.00 m below the surface of a liquid nitrogen lake is 5.00 × 105 N/m2 . At a de
eimsori [14]

Answer:

300000.01008 Pa

123.76237 m/s²

Explanation:

\rho = Density of liquid nitrogen = 808 kg/m³

h = Depth

g = Acceleration due to gravity

P = Atmospheric pressure

Absolute Pressure is given by

Below 2 m from surface

P_a=P+\rho gh\\\Rightarrow 5\times 10^5=P+808g\times 2

Below 5 m from surface

P_a=P+\rho gh\\\Rightarrow 8\times 10^5=P+808g\times 5

Subtracting the above equations we get

-3\times 10^5=-808g3\\\Rightarrow g=\frac{3\times 10^5}{808\times 3}\\\Rightarrow g=123.76237\ m/s^2

The acceleration due to gravity on the planet is 123.76237 m/s²

Equating the value of g in the first equation

5\times 10^5=P+808\times 123.76237\times 2\\\Rightarrow P=5\times 10^5-808\times 123.76237\times 2\\\Rightarrow P=300000.01008\ Pa

The atmospheric pressure on the planet is 300000.01008 Pa
