The Temperatureslider controls the heat of the metal filamentinside the light. Scientists use the Kelvin scaleto measure the tem

perature of very hot objects. It is like the Celsius scale except 0 K (absolute zero) is the coldest anything can ever be.Slowly move the Temperatureslider all the way to the right. What happens? ___________ the color changes. The light energy emitted by the flashlight is called radiation

Answer:

The after  the light changes to more energetic Violet light

Explanation:

This type of thermometer is called a pyrometer, the light from the bulb is facing the light received from the hot object by moving the knob to the right for more current through the filament and the light changes towards more energy, violet. When the intensity from the hot source and the deserter are the same, the radiation is absorbed and the device is black, at this time the temperature is read.

The after  the light changes to more energetic Violet light

goblinko [34]

Answer:

Δt = 5.29 x 10⁻⁴ s = 0.529 ms

Explanation:

The simple formula of the distance covered in uniform motion can be used to find the interval between when the sound arrives at the right ear and the sound arrives at the left ear.

\Delta s = v\Delta t\\\\\Delta t = \frac{\Delta s}{v}

where,

Δt = required time interval = ?

Δs = distance between ears = 18 cm = 0.18 m

v = speed of sound = 340 m/s

Therefore,

\Delta t = \frac{0.18\ m}{340\ m/s}

<u>Δt = 5.29 x 10⁻⁴ s = 0.529 ms</u>

at location a, what are the directions of the electric fields contributed by the electron. calculate the magnitudes of the elect
Lisa [10]

We can use the equation E = k | Q | r 2 E = k | Q | r2 to find the magnitude of the electric field. The direction of the electric field is determined by the sign of the charge,

<h3>What is electric and magnetic field ?</h3>

With the use of electricity and other types of artificial and natural illumination, invisible energy fields known as electric and magnetic fields (EMFs) and radiation are created.

  • While the magnetic field is discernible by the force it exerts on other magnetic particles and moving electric charges, the electric field is actually the force per unit charge experienced by a non-moving point charge at any given location inside the field.
