Answer: A. Electronegativity increases as you move to the right of the periodic table.

B. Electronegativity is the ability of an atom to attract electrons.

D. Electronegativity increases with a decreased number of protons.

Explanation:-

Electronegativity is defined as the property of an element to attract a shared pair of electron towards itself.

The size of an atom decreases as we move across the period because the electrons get added to the same shell and the nuclear charge keeps on increasing. Thus the electrons get more tightly held by the nucleus.

As, the size of an element decreases, the valence electrons come near to the nucleus. So, the attraction between the nucleus and the shared pair of electrons increases.

Electronegativity increases when the protons increases as then the pull on electrons will be more.

An archer practicing with an arrow bow shoots an arrow straight up two times. The first time the initial speed is vi and second
Amiraneli [1.4K]

Answer:

The maximum height reached in the second trial is 16times the maximum height reached in the first trial.

Explanation:

The following data were obtained from the question:

First trial

Initial speed (u) = v

Final speed (v) = 0

Second trial

Initial speed (u) = 4v

Final speed (v) = 0

Next, we shall obtain the expression for the maximum height reached in each case.

This is illustrated below:

First trial:

Initial speed (u) = v

Final speed (v) = 0

Acceleration due to gravity (g) = 9.8 m/s²

Height (h₁) =.?

v² = u² – 2gh₁ (going against gravity)

0 = (v)² – 2 × 9.8 × h₁

0 = v² – 19.6 × h₁

Rearrange

19.6 × h₁ = v²

Divide both side by 19.6

h₁ = v²/19.6

Second trial

Initial speed (u) = 4v

Final speed (v) = 0

Acceleration due to gravity (g) = 9.8 m/s²

Height (h₂) =.?

v² = u² – 2gh₂ (going against gravity)

0 = (4v)² – 2 × 9.8 × h₂

0 = 16v² – 19.6 × h₂

Rearrange

19.6 × h₂ =16v²

Divide both side by 19.6

h₂ = 16v²/19.6

Now, we shall determine the ratio of the maximum height reached in the second trial to that of the first trial.

This is illustrated below:

Second trial:

h₂ = 16v²/19.6

First trial:

h₁ = v²/19.6

Second trial : First trial

h₂ : h₁

h₂ / h₁ = 16v²/19.6 ÷ v²/19.6

h₂ / h₁ = 16v²/19.6 × 19.6/v²

h₂ / h₁ = 16

h₂ = 16 × h₁

From the above illustrations, we can see that the maximum height reached in the second trial is 16times the maximum height reached in the first trial.

The main purpose of any wave, including sound waves and ocean waves, is to
dybincka [34]

The main purpose of any wave, including sound waves and ocean waves, is to carry energy from one place to another.

A sound wave is the pattern of disruption brought on by the movement of energy moving through a medium as it propagates away from the source of the sound (such as air, water, or any other liquid or solid matter). Pressure waves are produced when an object vibrates, such as a ringing phone, and these waves are known as sound waves.

A wave crest is produced when wind continuously disturbs the water's surface in an ocean or lake. Ocean waves, which often go by the name wind waves, are mostly gravity waves. The height, duration, and shape of succeeding waves vary with a certain level of randomness of ocean waves.

A 55 kg women is running at the speed of 3 m/s what is her kenitic energy
zloy xaker [14]

Kinetic energy of the women can be calculated using the formula,

K.E = \frac{1}{2}mv^{2}

We have, mass of the women = 55 kg

Speed of the women = 3 m/s

Substituting the values we get,

Kinetic energy of the women= \frac{1}{2}55(3)^{2}

= 247.5 J
