The sun emits rays of heat and our solar panels take in that heat and transfer that heat into energy. Sun is also a way of keeping warm or thermal energy
Not going to explain how a solar panel transfers heat into electricity since that would take an entire college class period to explain.

A hardware salesman measures the mass of a box containing
sattari [20]

Step 1

<u>find the mass of a single washer</u>

Divide the total mass by the number of washers

\frac{0.4168}{1000} =0.0004168\ Kg

0.0004168kg=4.168*10^{-4} kg

Step 2

<u>Convert kg to mg</u>

we know that

1 kg=1*10^{6} mg

so

4.168*10^{-4}*10^{6} =4.168*10^{2}mg=416.8 mg

therefore

<u>the answer is</u>

416.8 mg

What is the wavelength of infrared radiation with a frequency of 3.85 x 10^12 Hz?
ELEN [110]

Answer:

Wavelenght is 7,79x10⁻⁵ m

Explanation:

The equation that connects wavelentgh (λ) and frequency (ν) is:

λ=c/ν

Where c is speed of light (3x10⁸ m/sec) and λ is expressed in lenght´s units and ν is expressed in "time⁻¹ " units (for example, sec⁻¹)

According to the details, if we just replace the given value of frequency, we just obtaing wavelenght data:

λ= (3x10⁸ m/sec)/(3,85x10¹² sec⁻¹) = 7,79x10⁻⁵ m

What is the mole fraction of ethanol in a solution of 3.00 moles of ethanol and 5.00 moles of water?
Rus_ich [418]
If theres a mixture of components we can calculate the mole fraction
mole fraction can be calculated as follows
mole fraction of component = \frac{number of moles of component}{total number of moles of all components }
number of moles of ethanol - 3.00 mol
total number of moles in mixture - 3.00 + 5.00 = 8.00 mol 

mole fraction of ethanol = \frac{3.00 mol}{8.00 mol }
mole fraction of ethanol is 0.375
