4 0

Answer:

(1.) gamma rays.    (2.) X-rays.   (3.) ultraviolet.    (4.) visible light.    (5.) infrared.

(6.) radio waves

Explanation:

Notice that these wavelengths span an enormous range. The wavelengths of gamma rays can be smaller than the size of an atomic nucleus, while the wavelengths of radio waves can be many meters (or even milometers) long. Visible light spans only a very narrow range of wavelengths, from about 400 nano meters at the blue (violet) end to about 700 nano meters at the red end.

One might be tempted to say that exothermic processes are always spontaneous since the system is emitting energy (heat) in order
Crank

Answer : This reaction occur spontaneously at temperature above in kelvins is, 340 K

Explanation : Given,

\Delta H = 17 KJ/mole = 17000 J/mole

\Delta S = 50 J/mole.K

Gibbs–Helmholtz equation is :

\Delta G=\Delta H-T\Delta S

As per question the reaction is spontaneous that means the value of \Delta G is negative or we can say that the value of \Delta G is less than zero.

\Delta G

The above expression will be:

0>\Delta H-T\Delta S

T\Delta S>\Delta H

T>\frac{\Delta H}{\Delta S}

Now put all the given values in this expression, we get :

T>\frac{17000J/mole}{50J/mole.K}

T>340K

Therefore, this reaction occur spontaneously at temperature above in kelvins is, 340 K

The answer to the question stated above is letter a. run at highest <span>speed.

</span>Jumpering out the resistors in a resistance-controlled three-speed fan will cause the motor to <span>run at highest speed. If resistors are jumpered, the three-speed fan will over speed and probably burns out.</span>
