Problem 5 You are playing a game where you drop a coin into a water tank and try to land it on a target. You often find this gam

Dvinal [7]

Answer:

Option D: 1.5in in front of the target

Explanation:

The object distance is $y= 6in$ .

Because the surface is flat, the radius of curvature is infinity .

The incident index is $n_i=\frac{4}{3}$ and the transmitted index is $n_t= 1$ .

The single interface equation is $\frac{n_i}{y}+\frac{n_t}{y^i}=\frac{n_t-n_i}{r}$

Substituting the quantities given in the problem,

$\frac{\frac{4}{3}}{6in}+\frac{1}{y^i}= 0$

The image distance is then $y^i=-\frac{18}{4}in =-4.5in$

Therefore, the coin falls $1.5in$ in front of the target

Mrrafil [7]

1. 408.4 J

The work done by a gas is given by:

$W=p\Delta V$

where

p is the gas pressure

$\Delta V$ is the change in volume of the gas

In this problem,

$p=1.01\cdot 10^5 Pa$ (atmospheric pressure)

$\Delta V=4048.3 cm^3 - 4.5 cm^3 =4043.8 cm^3 = 4043.8 \cdot 10^{-6}m^3$ is the change in volume

So, the work done is

$W=(1.01\cdot 10^5 Pa)(4043.8 \cdot 10^{-6}m^3)=408.4 J$

2. 10170 J

The amount of heat added to the water to completely boil it is equal to the latent heat of vaporization:

$Q = m \lambda_v$

where

m is the mass of the water

$\lambda_v = 2.26\cdot 10^6 J/kg$ is the specific latent heat of vaporization

The initial volume of water is

$V_i = 4.5 cm^3 = 4.5\cdot 10^{-6}m^3$

and the water density is

$\rho = 1000 kg/m^3$

So the water mass is

$m=\rho V_i = (1000 kg/m^3)(4.5\cdot 10^{-6}m^3)=4.5\cdot 10^{-3}kg$

So, the amount of heat added to the water is

$Q=(4.5\cdot 10^{-3}kg)(2.26\cdot 10^6 J/kg)=10,170 J$

False.

Force is found by multiplying mass of an object by its acceleration.

F = mass * acceleration
