Answer: Option A) Atoms to the left on the periodic table

Explanation:

The periodic table has metallic elements on the left side, semi-metal or metalloids in the middle, and nonmetallic elements of the right side.

Since, electronegativity of an atom tells of its power to attract electrons. Metals give off electrons rather than attract electrons like non-metals; thus, metals have the lowest electronegativity (with values less than 2.4 while nonmetal have high electronegativity values above 2.7

Infact, the element with the highest electronegativity is a non-metal (fluorine) while the element with the lowest electronegativity is a metal (potassium)

Thus, metallic atoms located on the left side of the periodic table have the lowest electronegativity

A basketball player can leap upward 0.43 m. how long does he remain in the air? use an acceleration due to gravity of 9.80 m/s2

MArishka [77]

From the equations of linear motion,
v² = u² + 2as where v is the final velocity, u is the initial velocity and a is the gravitational acceleration, and s is the displacement,
Thus, v² = u² -2gs, but v=0
hence, u² = 2gs
= 2×9.81×0.43
= 8.4366
u = √8.4366
=2.905 m/s
Hence the initial velocity is 2.905 m/s
Then using the equation v= u +gt .
Therefore, v = u -gt. (-g because the player is jumping against the gravity)
but, v = 0
Thus, u= gt
Hence, t = u/g
= 2.905/9.81
= 0.296 seconds

Make a conclusion on the relationship of mass to the rate of the change of motion of the balloon at a constant force.

sasho [114]

At a constant force, the mass of the balloon is inversely proportional to the rate of change motion of the balloon.

The force applied to an object can be determined by applying Newton's second law of motion, the force applied to an object is directly proportional to the product of mass and acceleration of the object.

F = ma

$F = m\frac{\Delta v}{t} \\\\\frac{F}{\frac{\Delta v}{t} } = m$

The mass of an object is inversely proportional to the rate of change motion of the object.

Thus, we can conclude that at constant force, the mass of the balloon is inversely proportional to the rate of change motion of the balloon.

A sample of gold has a volume of 2 cm3 and a mass of 38.6 grams. What would be the density, and three other properties of the sa

lukranit [14]

The density of the gold is calculated to be "19,300 kg/m³".

<u>Explanation:</u>

Given:

Volume = 2cm³

Mass = 38.6 grams.

To Find:

Density of the gold = ?

Solution:

Density is obtained by dividing mass of the sample by its volume and it is given in the units of kg/m³.

Mass in grams is converted into kg as,

1 g = 0.001 kg

38. 6 g = $\frac{38.6}{1000} = 0.0386 kg$

Now we have to convert cm³ to m³ as,

1 cm³ = 10⁻⁶ m³

2 cm³ = 2 × 10⁻⁶ m³

So Density = $\frac{0.0386 k g}{2 \times 10^{-6} m^{3}}=19,300 \mathrm{kg} / \mathrm{m}^{3}$

Physical properties of Gold:

Gold is a heavy metal.

It is Malleable and ductile.

It is a corrosion resistant element.

<span>A. accelerate toward the more massive object is your answer. In fact, even the acceleration with accelerate, also known as the jer.k. The more massive object will pull on the smaller object and the smaller object will increase its speed towards the more massive object.
