Answer:149.73 ml
Explanation:
Given

change in volume is given by

![\Delta V=\nu_{initial}\beta _{acetone}\left [ T_f-T_i\right ]](https://tex.z-dn.net/?f=%5CDelta%20V%3D%5Cnu_%7Binitial%7D%5Cbeta%20_%7Bacetone%7D%5Cleft%20%5B%20T_f-T_i%5Cright%20%5D)
![V_{final}=\nu_{initial}+\nu_{initial}\beta _{acetone}\left [ T_f-T_i\right ]](https://tex.z-dn.net/?f=V_%7Bfinal%7D%3D%5Cnu_%7Binitial%7D%2B%5Cnu_%7Binitial%7D%5Cbeta%20_%7Bacetone%7D%5Cleft%20%5B%20T_f-T_i%5Cright%20%5D)
![V_{final}=150+150\times 1.50\times 10^{-4}\left [ 20-32\right ]](https://tex.z-dn.net/?f=V_%7Bfinal%7D%3D150%2B150%5Ctimes%201.50%5Ctimes%2010%5E%7B-4%7D%5Cleft%20%5B%2020-32%5Cright%20%5D)

Answer:

Explanation:
From the question we are told that
The number of turns is 
The radius is 
The position from the center consider is x = 3.45 cm = 0.0345 m
The induced emf is 
Generally according to Gauss law

=> 
Where A is the cross-sectional area of the solenoid which is mathematically represented as

=> 
=>
ggl;
Here
is the permeability of free space with value

=> 
=> 
You need distance and time to find average speed.
Answer:
pretty sure its B if it isnt im so so sorry
Explanation:
Alright. If it’s running at a constant speed of 120 km/h, in one hour it will have traveled 120 kilometers. hence “kilometers per hour”
20 minutes is 1/3 of an hour so 120/3 will be 40
therefore, in 20 minutes the cheetah would’ve ran 40km if it maintained 120km/h for 20 minutes.
