The answer is:
All the above
The explanation:
The volume and the temperature and the number of particles will affect the pressure of an enclosed gas.
because according to boyle's law when the temperature constant so the pressure and volume of a gas have an inverse relationship, when temperature is constant.
when:
PV = nRT
when p is the pressure
V is the volume
n is number of moles
T is temperature
from this law we can know that there is a relation between P and V and when n has a relation with the number of particles so:
volume , temperature and number of particles affect the pressure of an enclosed gas.
Answer:
Option D
Explanation:
These advancements are very expensive and not available to everyone. The others are positive aspects of these advancements in transportation.
Answer:
1.974 g
Explanation:
Electrochemical equivalent of copper, z = 0.000329 g/C
I = 10 A
t = 10 minutes = 10 x 60 = 600 seconds
By the use of Farady's law of electrolysis
m = z I t
m = 0.000329 x 10 x 600
m = 1.974 g
Newton's Third Law of Motion states that springs exert a restoring force when they are pulled. The relationship between the spring force, spring constant, and spring displacement is governed by Hooke's Law.
Mass of the object= k*x/a= 26kg
what is Hooke's law?
The force (F) required to extend or compress a spring by a certain distance (x) scales linearly with respect to that distance, according to the empirical law known as Hooke's law.
according to Hooke's law
f=-k x (-ve because spring is compressing)
from force equation f=ma m-=mass, a= acceleration , k=spring constant, x= displacemt due to compression
so, ma=-k x, (mass can not be -ve so remove -ve sign)
m=k x/a= 40*2/3=26.67 kg
