Answer:
P = 359.8 atm
Explanation:
The van der Waals' equation relates the properties of a gas, introducing constants "a" and "b" in order to consider gases as real gases. The equation is:
where,
P: pressure
a: correction factor for intermolecular forces
V: volume
b: correction factor for molecules' volume
n: moles
R: ideal gas constant
T: absolute temperature
The image formed by a concave mirror with the object placed at the center of curvature is real inverted and formed at the center of curvature. Using the ray diagram a ray from the top of the object to the mirror through f then reflected parallel to the principal axis,then the ray through the center of curvature reflected through the same point both intersect at a plane through center curvature and perpendicular to the principal axis. The point of intersection forms the top of the image and the center of curvature forms the bottom. Therefore, the correct choices are : real and inverted
we know that,
Frequency = 1/ time period
hence, Feq = 1/5 ===> 0.2 Hz
hence, wave velocity = freq * wavelength
hence,
V = 0.2 * 100
==> Wave velocity = 20 m/s
Answer:
if the mass of both objects is doubled, then the force of gravity between them is quadrupled and so on
Answer: 
Explanation:
Firstly, let's convert these length to meters 
, in order to work with the same units:
a. 400 millimeters
b. 22 kilometers
c. 170 meters
Here the lenght is already in meters
d. 3.3 centimeters
Now that we have all the lengths in meters, we can order them from shortest to longest:
or
