Answer:
The overall velocity of the water when it hits the bottom is:

Explanation:
Use the law of conservation of energy.
Call it instant [1] to the moment when the water is just before reaching the falls.
At this moment its height h is 206 meters and its velocity horizontally
is
m/s.
At the instant [1] the water has gravitational power energy 

The water also has kinetic energy Ek.

Then the Total E1 energy is:

In the instant [2] the water is within an instant of touching the ground. At this point it only has kinetic energy, since the height h = 0. However at time [2] the water has maximum final velocity 
So:

As the energy is conserved then 

Now we solve for
.

Answer:
I think 1 is d and 2 is A

Answer:
The voltage drop through which the proton moves is 39.1 V.
Explanation:
Given that,
Distance = 4.76 cm
Time 
We need to calculate the acceleration
Using equation of motion

Where, s = distance
a = acceleration
t = time
Put the value in the equation



We need to calculate the voltage drop
Using formula of electric field

....(I)
Using newton's second law
....(II)
Put the value of F in equation (I) from equation (II)


Where, q = charge
a = acceleration
d = distance
m= mass of proton
Put the value into the formula


Hence, The voltage drop through which the proton moves is 39.1 V.
