Python lists are commonly used to store data types. Lists are a collection of information typically called a container. Think of

a physical container that can hold all kinds of objects, not just one object of the same type. Python includes a built-in list type called a list. They can be managed by many built-in functions that help fill, iterate over, add to, and delete a list. Why is it useful to store information with different data types?

Answer:

Explained

Explanation:

Data Type specifies the processor how much amount of memory to be reserved for  a variable.

For example :If a variable is declared as String or Integer this tells the processor  to stored this much of space for this variable to store the value.

List :

1.List is sort of an array used to store values of different data types

2.Lists are ordered .Element in the list are elements in a list are indexed according to a definite sequence and placed at a specific index.Lists can hold different data types.

Here is an example of List ,List = ['a', 1,'b',4,[a,b,c,1]

1. Dictionary is an dis ordered collection of data values, used to store data values .

2.Dictionary is for key,value maps , Keys of a Dictionary are (should be ) unique and of immutable data type such as Strings, Integers and tuples.

Dict = {1: 'Apple', 2: 'Boy', 3:'God',4:[1, 2, 3, 4]}

Each unique key holds a value.  So it depends on the requirement or scenarios where we have to chose between list or dictionary

Match each titration term with its definition.
Illusion [34]

Answer:

1) titration

2) titrand

3) equivalence point

4) titrant

5) Burette

6) Indicator

Explanation:

The process in which a known volume of a standard solution is added to another solution so that the standard solution can react with the solution of unknown concentration such that its concentration is determined  can be referred to as titration.

The solution which is added to another solution  is called the titrant.  The titrand is the solution of unknown concentration

A burette is a glassware used to slowly add a known volume of the titrant to the titrand.

The indicator used signals the point when the reaction is complete by a color change. At this point, a stoichiometric amount of titrant has been added to the titrand. This is also referred to as the equivalence point.

What is the velocity of flow in an asphalt channel that has a hydraulic radius of 3.404 m, length of 200 m and bed slope of 0.00
yKpoI14uk [10]

Answer:

The velocity of flow is 10.0 m/s.

Explanation:

We shall use Manning's equation to calculate the velocity of flow

Velocity of flow by manning's equation is given by

V=\frac{1}{n}R^{2/3}S^{1/2}

where

n = manning's roughness coefficient

R = hydraulic radius

S = bed slope of the channel

We know that for an asphalt channel value of manning's roughness coefficient = 0.016

Applying values in the above equation we obtain velocity of flow as

V=\frac{1}{0.016}\times 3.404^{2/3}\times 0.005^{1/2}\\\\\therefore V=10.000m/s

The basic barometer can be used to measure the height of a building. If the barometric readings at the top and the bottom of a b
Levart [38]

Answer:

230.51 m

Explanation:

Pb = 695 mmHg

Pt = 675 mmHg

Pb - Pt = 20 mmHg

Calculate dP:

dP = p * g * H = (13600)*(9.81)*(20/1000) = 2668.320 Pa

Calculate Height of building as dP is same for any medium of liquid

dP = p*g*H = 2668.320

H = 2668.32 / (1.18 * 9.81) = 230.51 m

1. Examine the following circuit. Find RT, I3, R1, R2, R3, V1, V2 and V3. Show all of your work clearly below.
Mkey [24]

Explanation:

Ohm's law is used here. V = IR, and variations. The voltage across all elements is the same in this parallel circuit. (V1 =V2 =V3)

The total supply current is the sum of the currents in each of the branches. (It = I1 +I2 +I3)

Rt = (8 V)/(8 A) = 1 Ω . . . . supply voltage divided by supply current

I3 = 8A -3A -4A = 1 A . . . . supply current not flowing through other branches

R1 = (8 V)/(3 A) = 8/3 Ω

R2 = (8 V)/(4 A) = 2 Ω

R3 = (8 V)/(I3) = (8 V)/(1 A) = 8 Ω

V1 = V2 = V3 = 8 V
