What kinds of energy does the Sun provide earth

2 answers:

7 0

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 $1$

find the mass of a single washer

Divide the total mass by the number of washers

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

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

Step $2$

Convert kg to mg

we know that

$1 kg=1*10^{6} mg$

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

therefore

the answer is

$416.8 mg$

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
