Answer:

The table can be used to predict the properties of elements, even those that have not yet been discovered. Columns (groups) and rows (periods) indicate elements that share similar characteristics. The table makes trends in element properties apparent and easy to understand. The table provides important information used to balance chemical equations. Atoms are important because they form the basic building blocks of all visible matter in the universe. There are 92 types of atoms that exist in nature, and other types of atoms can be made in the lab. The different types of atoms are called elements. Hydrogen, gold and iron are examples of elements comprised of unique types of a single kind of atom.

Write the equation of a wave traveling along the +x-axis with an amplitude of 0.02 m, a frequency of 440 Hz, and a speed of 330m

Airida [17]

The equation of the wave travelling along the +x-axis is y = 0.02 sin (880π/330 x – 880 πt)

Explanation:

Given data

Amplitude 0.02 m , Frequency= 440 Hz ,Speed = 330 m/s

The equation format is written as,

y = A sin ( k x – ω t)

We need the value of A, k, x -ω t

1. Find the k value

v = f ×λ

330 = 440×λ

k = 2π×λ

k = 880 π /330 m-1

440 ×2π = w

2. Find the ω value

f×2π =ω

ω = 880 π s-1

3. Find the A value

we get A value from the given data

A = 0.02 m

By the formula,

y = A sin ( k x – ω t)

Substitute the values we get the equation,

y = 0.02 sin (880π/330 x – 880 πt)

The equation of the wave travelling along the +x-axis is y = 0.02 sin (880π/330 x – 880 πt)

Now, remove the positive charge by dragging it back to the basket, and drag one negative charge toward the middle of the screen.

Bess [88]

The correct option is;

The voltages become negative instead of positive and keep the same magnitudes

Explanation: Here we have that there is a change in direction from positive to negative with the direction pointing to opposite of the initial direction whereby the field strength does not change due to the reversal of the. Therefore the voltage becomes negative instead of negative while keeping the the magnitude.

That is there is a electric field reversal or a change electric field direction.
