Calculate the energy, in electron volts, of a photon whose frequency is the following.
Tems11 [23]

Answer:

(a) E=2.42eV

(b) E=1.45*10^{-5}eV

(c) E=1.66*10^{-7}eV

Explanation:

The Planck-Einstein relation allows us to know the energy (E) of a photon, knowing its frequency (f). According to this relation, the energy of the photon is defined as:

E=hf

Here h is the Planck constant.

(a)

E=(4.14*10^{-15}eV\cdot s)(585*10^{12}Hz)\\E=2.42eV

(b)

E=(4.14*10^{-15}eV\cdot s)(3.50*10^{9}Hz)\\E=1.45*10^{-5}eV

(c)

E=(4.14*10^{-15}eV\cdot s)(40.0*10^{6}Hz)\\E=1.66*10^{-7}eV

Which statement below best describes the relationship between the voltage, resistance, and current?
aliina [53]

Answer:

As voltage increases, current increases and resistance stays the same .

Explanation:

Ohm's law gives the relationship between the voltage, resistance, and current. The mathematical form of Ohm's law is given by :

V\propto I\\\\V=IR

R is resistance

I is current

V is voltage

So, as voltage increases, current increases and resistance stays the same. The correct option is (A).

While doing the dishes, you drop an iron skillet that’s very hot (200° C or more) into a sink containing a few inches of water a
k0ka [10]

Remember the fact that every object has a specific amount of latent heat of vaporization

The specific heat capacity of iron and water are different

  • They may have same mass but not same specific heat capacity
  • So same amount of temperature can't create same amount of heat .
  • Also water is liquid so heat get transmitted through out the solution.

How does a submarine submerge and then float on water
vfiekz [6]

Answer:

Submarines have tanks called ballasts.  To submerge, the ballasts are filled with water.  This increases the submarine's mass which also increases its density, allowing it to sink.

To rise, compressed air is used to push the water out of the ballasts.  This decreases the submarine's mass which also decreases its density, allowing it to rise.
