The minimum number of photons of green light that can be detected by the human eye is 6.

Given that;

E = nhc/λ

E = energy of the photon = 2.35 * 10^-18 J

n = number of photons = ?

h = Planks constant = 6.6 * 10^-34 Js

c = speed of light = 3 * 10^8 m/s

λ = 510 * 10^-9 m

Making number of photons the subject of the formula;

n =2.35 * 10^-18 *  510 * 10^-9 / 6.6 * 10^-34 * 3 * 10^8

n = 6 photons

a particular car has a fuel efficiency for 8 liters of gasoline per 100 kilometers. What is the fuel efficiency in miles per gal
tresset_1 [31]

Answer:

35.31mpg

Explanation:

From the question given, the efficiency of the fuel in L/100km is given by: 8L/100km.

The efficiency of the fuel in miles per gallon can be obtained as follow:

1L/100km is equivalent to 282.481mpg.

To obtain 8L/100km in miles per gallon, we simply divide 282.481 by 8L/100km as shown below:

8L/100km in mpg = (282.481)/(8L/100km) = 35.31mpg

Therefore, the efficiency of the fuel in miles per gallon is 35.31mpg

Georgia’s scores in six subjects are 89, 75, 92, 68, 78, 75, and 80. If she finds a single value that summarizes all the values
Allushta [10]
Hey there! :)

Your answer is mean
_____________________________________________________________

Mean is the average value of the data set.
Mode is the number that appears the most
Range is the difference between the greatest value and the lowest value in a data set.

Finding the mode is pretty useless because you can't do much with the score that you got the most.

Range isn't that helpful because it's the difference between your best and worst score.

Mean is best for summarizing because you have 1 number that's the average of the whole data set.
______________________________________________________________

Therefore, the answer is mean

Hope this helps :)

Ipatiy [6.2K]
Hydrogen gas density is 0.08988 kg/m3 under STP (0°C, 1 atm), so the volume is
V=m / ρ = 18,000 / 0.08988 = 2.002 × 105 (m3).

A local news story claims that 53 of high school males agree with the statement.
horrorfan [7]

Based on the information given regarding the sampling, the correct option is E. No, because p = 0.53 was one of the most common values in the sampling distribution.

<h3>How to solve the sample.</h3>

From the complete information, it can be deduced that on the dotplot, the center of the sampling distribution is around 0.53. This means that if we construct a confidence interval, there is a high probability that it will have a value of 0.53.

Also, for less than 53% to be true, then most of the dots should have been less than 0.53. In this case, it is centered around 0.53 and so this illustrates that a lot of values are equal to and above 0.53.
