Answer: 247.67 V
Explanation:
Given
Potential At A 
Potential at 
when particle starts from A it reaches with velocity
at Point while when it starts from C it reaches at point B with velocity 
Suppose m is the mass of Particle
Change in Kinetic Energy of particle moving under the Potential From A to B

Change in Kinetic Energy of particle moving under the Potential From C to B

Divide 1 and 2 we get

on solving we get


Answer:
it is light
Explanation:
the arrow that says light is on the glass it must be near from tungsten
Answer:

Explanation:
Since fluid is pumping in and out at the same rate (5L/min), the total fluid volume in the tank stays constant at 350L. Only the amount of salt and its concentration changed overtime.
Let A(t) be the amount of salt (g) at time t and C(t) (g/L) be the concentration at time t
A(0) = 10 g
Brine with concentration of 1g/L is pouring in at the rate of 5L/min so the salt income rate is 5 g/min
The well-mixed solution is pouring out at the rate of 5L/min at concentration C(t) so the salt outcome rate is 5C g/min
But the concentration is total amount of salt over 350L constant volume
C = A / 350
Therefore our rate of change for salt A' is
A' = 5 - 5A/350 = 5 - A/70
This is a first-order linear ordinary differential equation and it has the form of y' = a + by. The solution of this is

So 
with A(0) = 10
c + 350 = 10
c = 10 - 350 = -340

Answer:
c. predation, competition, parasitism
Explanation:
The important and only biotic factors from the given choices that can affect the structure and organization of biological communities are predation, competition and parasitism.
These factors ensures that there are interaction between organisms of the same and different species and only occur in life.
Biotic factors are the living component of the ecosystem that dictates what happens therein.
- Predation is an interaction between two organisms in which the predator, bigger organism feeds on the prey, smaller organism.
- Competition occurs where two organism of the same or different species struggles for limited resources in the ecosystem.
- Parasitism is an interaction where one organism feeds on the another and it causes harm to it. The organism feeding on another is called the parasite. And the one it is dependent on is the host.
All of these are biotic factors.
