Consider a household that uses 22.0 kW-hour of electricity per day on average. Most of that electricity is supplied by fossil fu

Lelu [443]

Answer:

$A_{net} = 13.469\,m^{2}$

Explanation:

The daily energy consumption of the household is:

$\Delta E_{day} = (22\,kWh)\cdot (\frac{3600000\,J}{1\,kWh} )$

$\Delta E_{day} = 79200000\,J$

The needed area of solar panel to power the household is:

$\Delta E_{day} = \eta\cdot G\cdot A_{net}\cdot \Delta t$

$A_{net} = \frac{\Delta E_{day}}{\eta\cdot G\cdot \Delta t}$

$A_{net} = \frac{79200000\,J}{(0.181)\cdot (376\,\frac{W}{m^{2}} )\cdot (86400\,s)}$

$A_{net} = 13.469\,m^{2}$

A laser beam is incident at an angle of 30.2° to the vertical onto a solution of corn syrup in water. (a) If the beam is refract

mote1985 [20]

Answer:

a) n2 = 1.55

b) 408.25 nm

c) 4.74*10^14 Hz

d) 1.93*10^8 m/s

Explanation:

a) To find the index of refraction of the syrup solution you use the Snell's law:

$n_1sin\theta_1=n_2sin\theta_2$ (1)

n1: index of refraction of air

n2: index of syrup solution

angle1: incidence angle

angle2: refraction angle

You replace the values of the parameter in (1) and calculate n2:

$n_2=\frac{n_1sin\theta_1}{sin\theta_2}=\frac{(1)(sin30.2\°)}{sin18.82\°}=1.55$

b) To fond the wavelength in the solution you use:

$\frac{\lambda_2}{\lambda_1}=\frac{n_1}{n_2}\\\\\lambda_2=\lambda_1\frac{n_1}{n_2}=(632.8nm)\frac{1.00}{1.55}=408.25nm$

c) The frequency of the wave in the solution is:

$v=\lambda_2 f_2\\\\f_2=\frac{v}{\lambda_2}=\frac{c}{n_2\lambda_2}=\frac{3*10^8m/s}{(1.55)(408.25*10^{-9}m)}=4.74*10^{14}\ Hz$

d) The speed in the solution is given by:

$v=\frac{c}{n_2}=\frac{3*10^8m/s}{1.55}=1.93*10^8m/s$

How many miles of MgCI2 are there in 339g of compound?

harkovskaia [24]

I'm going to answer this by using rounded numbers for the atomic masses. You need only go back and put the numbers in from your periodic table. My answers will be close, but not what you should get.

Find the Molar Mass of MgCl2

Mg = 24 grams

2Cl = 2 * 35.5 = 71 grams

Total = 95 grams

Find the mols in 339 grams

1 mole = 95 grams

x mol = 339

Solve

339 = 95x Divide by 95

339/95 = x

x = 3.67 mols Answer
