5. Bill is swimming and drops his swim goggles in the pool. He looks from above the top of the water to see where they fell and

positions himself directly above the goggles. He dives down to the bottom of the pool with his eyes closed so that the chlorine doesn't burn his eyes. He tries several times to retrieve his goggles but comes up empty handed each time. Which interaction of light is distorting the image of where his goggles appear to be?

The interaction of light that distorted the image of where Bill's goggles appear to be is Refraction.

<h3>What happens to the speed of light when it hits water in a swimming pool?</h3>

The light slows down when it passes from the less dense air into the water, this slow down of the ray of light which  causes the ray of light to change direction and then the changes the speed of the light that causes refraction.

The swimming pool appears shallow than it appear to be  because the rays of light coming from the bottom of the swimming pool that is refracted by the water making the height of the swimming pool to be above the actual swimming pool bed and there by misleading the observer(Bill).

Light with a wavelength of 395 nm illuminates a metal cathode. The maximum kinetic energy of the emitted electrons is 0.76 eV .
lutik1710 [3]

Answer:

520.8 nm

Explanation:

We are given that

\lambda=395 nm=395\times 10^{-9} m

1 nm=10^{-9} m

Maximum kinetic energy,K_{max}=0.76 eV=0.76\times 1.6\times 10^{-19} V

1 e=1.6\times 10^{-19} C

We have to find the maximum wavelength of light.

We know that

h\nu=\frac{hc}{\lambda_0}+K_{max}

Where c=3\times 10^8 m/s

h=6.625\times 10^{-34}

6.625\times 10^{-34}\times \frac{3\times 10^8}{395\times 10^{-9}}=\frac{6.625\times 10^{-34}\times 3\times 10^8}{\lambda_0}+0.76\times 1.6\times10^{-19}

6.625\times 10^{-34}\times \frac{3\times 10^8}{395\times 10^{-9}}- 0.76\times 1.6\times10^{-19}=\frac{6.625\times 10^{-34}\times 3\times 10^8}{\lambda_0}

\lambda_0=\frac{6.625\times 10^{-34}\times 3\times 10^8}{6.625\times 10^{-34}\times \frac{3\times 10^8}{395\times 10^{-9}}- 0.76\times 1.6\times10^{-19}}

\lambda_0=5.208\times 10^{-7} m=520.8 nm

A proton that has a mass m and is moving at +164 m/s undergoes a head-on elastic collision with a stationary carbon nucleus of m
Irina18 [472]
The concept of this problem is the Law of Conservation of Momentum. Momentum is the product of mass and velocity. To obey the law, the momentum before and after collision should be equal:

m₁ v₁ + m₂v₂ = m₁v₁' + m₂v₂', where
m₁ and m₂ are the masses of the proton and the carbon nucleus, respectively,
v₁ and v₂ are the velocities of the proton and the carbon nucleus before collision, respectively,
v₁' and v₂' are the velocities of the proton and the carbon nucleus after collision, respectively,

m(164) + 12m(0) = mv₁' + 12mv₂'
164 = v₁' + 12v₂'  --> equation 1

The second equation is the coefficient of restitution, e, which is equal to 1 for perfect collision. The equation is

(v₂' - v₁')/(v₁ - v₂) = 1
(v₂' - v₁')/(164 - 0) = 1
v₂' - v₁'=164 ---> equation 2

Solving equations 1 and 2 simultaneously, v₁' =  -138.77 m/s and v₂' = +25.23 m/s. This means that after the collision, the proton bounced to the left at 138.77 m/s, while the stationary carbon nucleus move to the right at 25.23 m/s.

The pressure of a gas is reduced from 1200.0 mm hg to 850.0 mm hg as the volume of its container is increased by moving a piston
Kamila [148]
From gas laws:
\frac{PV}{T} = Constant

Therefore,
\frac{ P_{1}  V_{1} }{ T_{1} } =  \frac{ P_{2}  V_{2} }{ T_{2} }

P1 = 1200 mm
V1 = 85 ml
T1 = 90°C = 363.15 K
P2 = 850 mm
V2 = 350 ml
T2 = ?

Substituting;
T_{2} =  \frac{ P_{2}  V_{2}  T_{1} }{ P^{1}  V^{1} } =  \frac{850*350*363.15}{1200*85} = 1059.19 K = 786.04 °C
