A. less than
In fact, the resistance will be less than that of the lowest resistance resistor.
The tank has a volume of 
, where 
is its height and 
is its radius.
At any point, the water filling the tank and the tank itself form a pair of similar triangles (see the attached picture) from which we obtain the following relationship:
The volume of water in the tank at any given time is
and can be expressed as a function of the water level alone:
Implicity differentiating both sides with respect to time 
gives
We're told the water level rises at a rate of 
at the time when the water level is 
, so the net change in the volume of water 
can be computed:
The net rate of change in volume is the difference between the rate at which water is pumped into the tank and the rate at which it is leaking out:
We're told the water is leaking out at a rate of 
, so we find the rate at which it's being pumped in to be
Heya!!!
Answer to your question:
All you need to do is to compare both the equations...
On comparing, you'll get
d=6m
v=6.5m/s
a=-9.81m/s^2
we know,
6= 6.5t -0.5 (9.81)t^2
6=6.5t-4.905 t^2
4.905 t^2-6.5t +6=0
now you can use quadratic eq. to solve this.
Hope it helps ^_^
Answer:
HCI creates an acidic environment, which promotes the process of pepsin.
When that happens, pepsin is maximally active and works on a fully digestion of the presented protein.
On the other hand HCI prevents the activeness of the amylase, thereby only a small part of starch is digested.
Explanation:
The physiological significance of these effects are: salivary glands found in the mouth which has a neutral pH environment segregates amylase, meanwhile pepsinogen becomes pepsin thanks to the compatibility with this environment.
While pepsin is widely active at a lower pH inside the stomach, amylase activity, on the other hand decreases at lower pH environment.
