In a television picture tube the electrons are accelerated from rest through a potential difference V. Just before an electron strikes the screen, its de Broglie wavelength is 8.00 10-12 m. What is the potential difference

V = 23515.53volt

Explanation:

wavelength λ= 1.1 x 10 -11 m

We know λ= h /√ [2mVq]

Where h = Plancks constant

            = 6.625 x 10 -34 J s

        m = mass of electron

           = 9.11 x 10 -31 kg

         q = charge of eectron

           =1.6 x 10 -19 C

From above potential difference V = ( 1/2mq) (h /λ)²

V = 23515.53volt

hi there!

your question asks at which segment does freezing occur.

since we're talking about water, the freezing point of water will be 32 degrees fahrenheit or below.

hope this ! ~

c because the action was the roller coaster reaches bottom of hill (action) reaction would be blood tends to drain away from head

hope this !
