How should the table be changed to correctly distinguish between mechanical and electromagnetic waves? earth earthquake waves and radiation waves need to change places. light waves and x-ray waves need to change places ocean waves and x-ray waves need to change places. sound waves and light waves need to change places.

Sound waves and light waves need to change places.

Explanation:

The electromagnetic spectrum has 7 different types of waves with wave different wave lengths and frequencies. They include radio waves, micro waves, infrared eradication, visible light, ultraviolet, xrays, and gamma rays. They do not require a medium of air or water. Mechanical waves need air and water to spread.

Sound waves and light waves need to change

Explanation:-

Electromagnetic waves are waves which can travel through the vacuum. electromagnetic waves have electrical and magnetic component associated with them. They all travel with the speed of light.The energy transport through a medium involves the absorption and re emission of the wave energy by the atoms of the material.  Example: Light waves, X rays, Radiation waves

Mechanical waves require a medium to travel so that they can transport their energy from one location to another.  Example: Ocean waves, sound waves , Earthquake waves

Thus light waves are electromagnetic waves and sound waves are mechanical waves and thus should exchange places.

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation

this is not my own answer, this is an answer for the same question by the user blahblahmali. i do not claim ownership of this account.

a electronegativity decreases beacuse the size of nucleus is bigger.
