<span>Like charges repel and opposite charges attract.
The further away two charged objects are the weaker the electrical force between them.
The closer two charged objects are the stronger the electrical force between them.

Answer:

Option (2), (4), (6)

Explanation:

According to the properties of charges, two like charges repel each other and two unlike charges attract each other.

If two positive or two negative charges kept at a distance, then they repel each other.

If one positive and one negative charges kept at a distance, they always attract each other.

Now according to the Coulomb's law, the force between the two charges, is directly proportional to the product of two charges and inversely proportional to the square of distance between them.

So, farther the two charges, weaker is the force.

And closer the two charges, stronger is the force.

Write down an equation describing a sinusoidal traveling wave (in 1-D). Tell us (words and/or equations) what in your equation t
Natalija [7]

Answer:

Explanation:

The standard equation of the sinusoidal wave in one dimension is given by

y = A Sin\left ( \frac{2\pi }{\lambda }\left ( vt-x \right )+\phi  \right )

Here, A be the amplitude of the wave

λ be the wavelength of the wave

v be the velocity of the wave

Φ be the phase angle

x be the position of the wave

t be the time

this wave is travelling along positive direction of X axis

The frequency of wave is f which relates with velocity and wavelength as given below

v = f x λ

The relation between the time period and the frequency is

f = 1 / T.

A tightrope walker more easily balances on a tightwire if his pole
cestrela7 [59]
B) droops.

Why?
To maintain balance, you do not need something short so you're balanced well... You need something long and droopy to maintain balance. The pole should be held by your waist and it should be light.

Hope this helps!~
