property of gas
gas molecules are very loosely bonded with each other so the force between the molecules is very weak
Due to this weak force the molecules of gas can attain any shape and any volume.
So gas moles have no finite shape and no finite volume
Property of Solids
Solids are tightly packed and having very strong bond between the molecules
If all molecules are tightly bonded then they have always a finite shape and finite volume so in this case we can not change the volume or shape of the solids as it is fixed.
Property of Liquids
Liquid molecules are moderately bonded together and since the force is more than the force between the gas molecules so liquids have finite volume but indefinite shape
liquid attains the shape of the container but its volume is fixed
So in above all examples Liquid is correct answer
Are there a list of things to choose from, without that its hard to answer
<span>In order to answer her question regarding how many students at her high school had summer jobs Nan must follow the procedure given in answer option B: First, randomly select 100 students, then ask them if they have summer jobs. In statistics this method is known as Population Sampling. These 100 students are chosen at random in order to avoid bias - we need them to be representative of the entire high school population.</span>
Answer:
The bicyclist's acceleration is 2.2m/s^2
Explanation:
Given
---- Initial Velocity
---- Final Velocity
---- Time
Required
Determine the acceleration
This will be solved using the first equation of motion
![v = u + at](https://tex.z-dn.net/?f=v%20%3D%20u%20%2B%20at)
Substitute values for v, u and a
![12.5 = 2.5 + a * 4.5](https://tex.z-dn.net/?f=12.5%20%3D%202.5%20%2B%20a%20%2A%204.5)
![12.5 = 2.5 + 4.5a](https://tex.z-dn.net/?f=12.5%20%3D%202.5%20%2B%204.5a)
Collect Like Terms
![4.5a = 12.5 - 2.5](https://tex.z-dn.net/?f=4.5a%20%3D%2012.5%20-%202.5)
![4.5a = 10.0](https://tex.z-dn.net/?f=4.5a%20%3D%2010.0)
Solve for a
![a = 10.0/4.5](https://tex.z-dn.net/?f=a%20%3D%2010.0%2F4.5)
---- (approximated)
<em>Hence, the bicyclist's acceleration is 2.2m/s^2</em>
