The major transition occurred is that the universe became transparent to light for the first time. This is the consequence that might happen because of the changes in the universe at this time. The reaction between the elements that are present in the space can affect the present universe.

If the pressure is 100,000 Pa, R is 8.314, the temperature is 300 K, and the number of moles of gas (n) is 100, what is the volu

djyliett [7]

We can solve the problem by using the ideal gas equation:
$pV=nRT$
where
p is the pressure of the gas
V is the volume of the gas
n is the number of moles of the gas
R is the gas constant
T is the absolute temperature of the gas

For the gas in our problem, we have:
$p=100000 Pa$
$R=8.314 J mol^{-1} K^{-1}$
$T=300 K$
$n=100$

If we rearrange the equation and we put these numbers into it, we find the volume of the gas:
$V= \frac{nRT}{p}= \frac{(100)(8.314)(300)}{100000}=2.49 m^3$

A cart travels down a ramp at an average speed of 5.00 centimeters/second. What is the speed of the cart in

Lostsunrise [7]

A cart travels down a ramp at an average speed of 5.00 centimeters/second. What is the speed of the cart in miles/hour? To solve this problem we have set the conversion values to determine the product during the conversion process. 
1. 1 centimeter = 0.00000621371 mile 
2. 1 hour = 60 minutes 3. 1 minute = 60 seconds
Thus, we shall have
1. 5 cm x 0.00000621371 mile/1cm = 0.000031069 mi
2. 0.000031069 seconds x 1 hr / 3600 = 0.111846815 miles / hr
