Answer: V2= 15.0403226 Liters
Explanation:
Use V1/T1=V2/T2
Make sure you change the degrees Celsius to Kelvin. (Kelvin = degrees Celsius +273)
10.0L / 248 K = V2/ 373 K
Cross multiply V1 and T2 and divide by T1
(10.0 L)( 373K)/ 248 K = V2
V2= 15.0403226 Liters (Kelvin cancels out)
Answer:
444 L
Explanation:
According to Archimedes the buoyancy force is equal to the weight of the displaced substance. In this case, the displaced substance is Air. So to calculate the lifting power of Helium, start with the weight of air in volume
Since the Helium itself has weight, we need to use the difference in density between air and helium.
We know that the density of air is 1.2
Density of Helium is 0.1787
To lift a object of 1 pound which is equal to 0.453 kg we need
helium There is 1000 liters in a
So the required volume of helium= 0.444×1000=444 L
The frequency of this photon is 5.94 x .
Solution:
The speed of light has a value of approximately <u>3.00×108 m/s</u>
The wavelength should have units of meters.
The frequency should have units of Hz or s−1. Hz is hertz or reciprocal seconds.
We know the value of the speed of light and we are given the wavelength. All we have to do is rearrange the equation to solve for the frequency:
<u>v = c/λ</u>
= 3.00× m/s/505×
m
= 5.94Xs-1
= <u>5.94X</u><u> Hz</u>

Frequency describes the number of waves passing through a particular location at a particular time. A class interval frequency is the number of observations that occur in a particular predefined interval. So, for example, if 20 of her ages 5-9 appear in the survey's data, the interval 5-9 has a frequency of 20. The class interval endpoints are the lowest and highest possible values of the variable.
