Help me FAST! please. I will give BRAINLIEST 1. what form of electromagnetic radiation do x-rays use
2. what form of electromagnetic radiation do remote controls use

Answers

Answer:

The X-Rays have ranges of energies from  100 eV to 200 keV, this range is commonly knowed as X-Radiation, but the original name is "Röntgen radiation", after the scientist who discovered it, Wilhelm Röntgen.

The electromagnetic radiation that remote controls use is the Infrared radiation (or infrared light), where the energy is lower than the one of the visible light (this is why is called "infrared", because is below of the red frequency) and this is why you can not see these wave signals.

Tim adds salt as he starts to heat a pot of water to cook pasta. When the water is boiling, he notices the salt has dissolved

Answers

Answer:

The salt is dissolved by the water and heat. If the pot isn't boiling, the salt wouldn't dissolve, it would stay undissolved.

A car traveling in a straight line has a velocity of 6m/s at some instant. After 6.32s its velocity is 13.2m/s . What is the average acceleration in this time interval?

Answers

Average acceleration  =  (change in speed) / (time for the change) .

Average acceleration  =  (13.2 - 6) / (6.32) = 7.2 / 6.32 = about  1.139... m/s² .

Answers

Answer:

-5.63 m/s

Explanation:

Given:

y₀ = 1.62 m

y = 0 m

v₀ = 0 m/s

a = -9.8 m/s²

Find: v

v² = v₀² + 2a (y − y₀)

v² = (0 m/s)² + 2(-9.8 m/s²) (0 m − 1.62 m)

v = -5.63 m/s

A +0.2 µC charge is in an electric field. What happens if that charge is replaced by a +0.4 µC charge?

Answers

Whenever that charge would be substituted with a +0.4 C charge, this same electric potential remains unchanged, however, the electrostatic potential energies increases.

Electric field

It has been well understood that the electric field is responsible for the generation of electric potential. As nothing more than a consequence, it is determined only by the electric field and not that the amount of the charge.

As a result, whenever a charge is multiplied by two, the overall electric potential remains constant. Since that day, the phrase for calculating electric potential seems to be as follows.

→ U = qV

Thus the response above is correct.

Find out more information about the electric field here:

Explanation:

It is known that electric field is responsible for creating electric potential. As a result, it depends only on the electric field and not on the magnitude of charge.

So, when a charge is increased by a factor of 2 then electric potential will remain the same. Since, expression to calculate the electric potential is as follows.

                 U = qV

Since, the electric potential is directly proportional to the charge. Hence, when 0.2 tends to replaced by 0.4 then charge is increased by a factor of 2. Hence, the electric potential energy is doubled.

Thus, we can conclude that if that charge is replaced by a +0.4 µC charge then electric potential stays the same, but the electric potential energy doubles.
