Answer:
resistances is inversely proportional to the area of cross section of the conductor
Answer:
The final pressure of oxygen gas is 8.33 atm.
Explanation:
From the given data
V=26 m^3 or 26000 L
T1=270K
T2=440K
n1=6000 moles
R=0.0821 L.atm/molK
Now from the ideal gas equation

As the options given are not defined in which unit thus the final pressure of oxygen gas is 8.33 atm.
<em>*The options are provided for a different question where </em>
Answer:
a) 
b) 
c) Generally the most probable speed is 8m/s as it the most posses by particles being the average
Explanation:
From the question we are told that:
Sample size N=15

Generally the equation for Average speed is mathematically given by

Therefore


b)
Generally the equation for RMS speed of the particle is mathematically given by




c
Generally the most probable speed is 8m/s as it the most posses by particles being the average
Answer:
A. 20 N down
Explanation:
It's asking how much force of gravity is acting on it. The book weighs 20 Newtons so that's how much gravity is being applied. Hope this helps
