Solution:
As per the question:
Hall emf,
Magnetic Field, B = 0.10 T
Hall emf,
Now,
Drift velocity,
Now, the expression for the electric field is given by:
(1)
And
Thus eqn (1) becomes

The answers are located in each of the explanations showed below
Explanation:
a)
(i) Surface Tension: The tensile force that causes this tension acts parallel to the surface and is due to the forces of attraction between the molecules of the liquid. The magnitude of this force per unit of length is called surface tension.
σ = F/l [N/m]
where:
F = force [N]
l = length [m]
σ = Surface Tension [N/m]
(ii) Frequency is the number of repetitions per unit of time of any periodic event.
f = 1/T [1/s] or [s^-1] or [Hz]
where:
T = period [s] or [seconds]
f = frecuency [Hz] or [hertz]
(iii) Each of the units will be shown for each variable
v = velocity [m/s]
a = accelertion [m/s^2]
s = displacement [m]
b) To find the velocity we must derivate the function X with respect to t because this derivate will give us the equation for the velocity, it means:
ii) replacing in the derivated equation.
iii) the average velocity is defined by the expresion v = x/t

a) Pascal's principle or Pascal's law, where the pressure exerted on an incompressible fluid and in balance within a container of indeformable walls is transmitted with equal intensity in all directions and at all points of the fluid.
Therefore:
P1 = pressure at point 1.
P2 = pressure at point 2.
P1 = F1/A1
P2= F2/A2
b) One of the applications of the surface tension is the <u>capillarity</u> this is a property of liquids that depends on their surface tension (which, in turn, depends on the cohesion or intermolecular force of the liquid), which gives them the ability to climb or descend through a capillary tube.
Other examples of surface tension:
The mosquitoes that can sit on the water.
A clip on the water.
Some leaves that remain floating on the surface.
Some soaps and detergents on the water.
There isn't a direct answer to this, but I can show you!
This is how you group Pennies, Nickels, and Dimes.
1 Penny= 1 cent.
1 Nickel= 5 cents.
1 Dime= 10 cents.
Imagine if there was 5 pennies, 3 dimes, and 8 Nickels.
That might seem like a lot of numbers, but it's pretty simple!
You know how pennies are worth 1 cent? If we had 5 pennies, that would be 5 cents.
1+1+1+1+1=5 cents.
Then, we have 3 dimes. Dimes are each 10 cents.
So, 10x3 (If you know multiplication, if not, you will learn it later) :)
10+10+10= 30 cents.
Now, nickels. We have 8 nickels! Remember, each nickel is 5 cents.
5+5+5+5+5+5+5+5=
40 Nickels.
Now add all of the coins up.
5 cents + 30 cents + 40 cents = 75 cents!
I hope this helped! If you need more help, you can ask me. :)
