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

Friction causes kinetic energy to be converted into what energy

Gennadij [26K]

Friction causes kinetic energy to be converted into 'thermal energy'. The answer to this question is 'thermal energy'. An example would be if something is being rubbed against another object, there is friction and thermal energy will be produced. I hope this helps you on your assignment! You're welcome.

Prove that young modulus of elasticity and pressure have the same dimensions

ivann1987 [24]

Answer:

The dimensions of Young's Modulus, as well as material stress, are the same as pressure because stress is like pressure in a solid, except with some key differences that warrant the use of different terminology.

A balloon is 3m in diameter and is filled with 5 kg of N2. Find the specific volume of the gas in the balloon. Express it in bo

enyata [817]

Answer:

The the specific volume and weight are 79.16m³/k mol and 49 N.

Explanation:

Given that,

Diameter = 3 m

Mass of N₂ = 5 kg

We need to calculate the volume of balloon

Using formula of volume

$V= \dfrac{4}{3}\pi r^3$

$V= \dfrac{4}{3}\pi \times{\dfrac{d}{2}}^3$

$V= \dfrac{4}{3}\pi \times(\dfrac{3}{2})^3$

$V=14.137\ m^3$

We need to calculate the specific volume in the balloon

$Specific\ volume=\dfrac{Volume}{mass}$

$Specific\ volume=\dfrac{14.137}{5}$

$Specific\ volume=2.8274\ m^3/kg$

Now, Molar mass of N₂ gas is 0.028 kg/mol

Now, Specific volume of N₂ gas in the balloon is

$Specific\ volume =0.028\times2.8274=0.0791672\ m^3/mol$

$Specific\ volume =79.16m^3/kmol$

(b). We need to calculate the weight of the gas in the balloon

Weight of the balloon is dependent on the mass of the gas.

The weight of the gas is given by

$W = mg$

$W = 5\times9.8$

$W = 49\ N$

Hence, The the specific volume and weight are 79.16m³/k mol and 49 N.
