Answer:
-2.79 x 10²J
Explanation:
using the pressure volume work formula which states that
work = -PΔV
= -(1.0 atm) (2.7-0.0)L = -2.7L . atm
Convert litre.atmosphere to Joules.
1 L . atm = 101.325 joules
-2.75 L .atm = -2.75 x 101.325 = -278.64375 =
Work = -2.79 x 10²J
Answer: D. Storage spaces in the cell.
Explanation: The organelle labeled E is called a vacuole and it’s used for storage in both plant and animal cells.
The focal length would likely decrease as the refractive index and the increase when the curvature radius of the lens increases. The decrease in focal length happens since a higher index of refraction would signify that the rays of the sun striking to an object would tend to bend more.
Moles x Mol mass = mass.
<span>Having looked it up, the mol.mass of U-238 is 238.03g/mol. </span>
<span>7.50 moles x 238.03g/mol. = 1,785.23g/mol</span>
Your first step is to find the circumference of the earth, with the numbers given. You can do that by putting the radius of 6200 kilometres into the 2πr equation. That should get you a circumference of 12400π, or about 38,955.75 kilometres.
Next, you can use the rate the Jetson's car is going (180km/h) and divide the 38,955.75 by it to see how many hours it would take at that constant speed.
38,955.75 / 180 = 216.42 hours
Then you can divide that by 24 to get how many days
