Answer:
Explanation:
Let be % of at time (time in minutes).
Amount of in room=Volume of room
Rate of change of in room=Volume of room x
Rate of inflow of =
Rate of outflow
Therefore rate of change of is
% rate of change is
Therefore we have:
Integrate both:
InIn
Raise both sides to base ,
Initially, there's only 0.25% of ,
Now substitute and
To me I would most think the answer is A.

Answer
there are strong attractive forces between atoms of liquids with a high viscosity
Explanation:
viscosity:
Viscosity is the state of being sticky and thick . There are strong attractive forces between atoms of liquids with a high viscosity on the other hand in non viscous liquid there are weak attractive forces between atoms of liquids. A semi fluid liquid like jelly is said to be viscous. Viscosity increases with stronger inter molecular forces at normal temperature. Viscosity decreases as temperature increases
Hope this answer will help you
Answer:
c) The slope is not constant and increases with increasing time.
Explanation:
The equation for the position of this particle (starting from rest is)
We can take derivative of this with respect to time t to get the equation of slope:
As time t increase, the slope would increases with time as well.
