Answer:
F = 755 N and h = 10.0 m and a = 9.8 m/s 2 and m=? and v = ?
Answer:
one of the object is at rest after the collision
Answer:a
Explanation:
Given
![[H^+]=5.3\times 10^{-4}\ M](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3D5.3%5Ctimes%2010%5E%7B-4%7D%5C%20M)
and 
Also ![pH=-\log [H^+]](https://tex.z-dn.net/?f=pH%3D-%5Clog%20%5BH%5E%2B%5D)
therefore 


Thus 

and ![pOH=-\log [OH^{-}]](https://tex.z-dn.net/?f=pOH%3D-%5Clog%20%5BOH%5E%7B-%7D%5D)
![[OH]^{-1}=10^{-10.25}](https://tex.z-dn.net/?f=%5BOH%5D%5E%7B-1%7D%3D10%5E%7B-10.25%7D)
![[OH]^{-1}=1.88\times 10^{-11}\ M](https://tex.z-dn.net/?f=%5BOH%5D%5E%7B-1%7D%3D1.88%5Ctimes%2010%5E%7B-11%7D%5C%20M)
As the pH is less than 7 therefore solution is acidic
Answer:
The car's angular speed is
.
Explanation:
Angular velocity is usually measured with
, so I'm going to use that to answer your question.
The relationship between tangential velocity and angular velocity (ω) is given by:

Using the values from the question, we get:


Therefore, the car's angular speed is
.
Hope this helped!
