give me some answer please I make you brainlist ​

Answer:

Ernest Rutherford performed an experiment to know the arrangement of electrons within an atom. In this experiment, fast-moving alpha particles were made to fall on a thin gold foil (100 nm thickness). The a-particles are doubly charged helium ions. It was expected that a-particles would be deflected by subatomic particles in the gold atom. Since a-particles were much heavier than protons, he did not expect to see large deflections.

But, the a-particle scattering experiment gave totally unexpected results.

The following observations were made: (i) Most of the fast-moving -particles passed straight through the gold foil.

(ii) Some of the -particles were deflected by the foil by small angles.

(iii) Surprisingly one out of every 12000 particles appeared to rebound.please add brainliest

Explanation:

Answer:

Correct option is B)

Eukaryotes are the organisms which have membrane-bound cell organelles as well as membrane-bound nucleus. All the kingdoms except kingdom monera possess eukaryotes.

Paramecium caudatum and Amoeba proteus are the protozoans belonging to kingdom Protista. So, they are eukaryotes.

Euglena viridis also belongs to kingdom Protista. It is a protistan algae.

Escherichia coli is not a eukaryote. It is a gram -ve bacteria belonging to kingdom Monera. Monera is a kingdom of prokaryotes. They do not have membrane-bound organelles and an organised nucleus.

Answer:

option B.

Explanation:

the ability to query data as well as insert delete and ulta tuples is offered by DCL.

Data Manipulation Language (DML) is used to query data as well as  insert, delete and alter tuples

Explanation:

DDL (Data Definition Language):

It is responsible for the database's generation and destruction. It includes statements for creating/defining databases, modifying their structure once they've been formed, and destroying them when they're no longer needed.

Data Manipulation Language (DML)

Data Manipulation Language (DML) is a programming language that allows you to manipulate data. It's used to work with the database.

Inserting, modifying, deleting, or querying data in a database is referred to as manipulation.

It allows users to view or manipulate data that has been structured according to the relevant data model.

DCL (Data Control Language)

DCL (Data Control Language) is a programming language for granting and robbing database access, auditing database usage, and managing with transactions.

It explains how to limit a user's or a group of users' access to only particular parts of the data and to run only certain types of queries.

TCL (Transaction Control Language):

TCL (Transaction Control Language):is a programming language that is used to control the changes produced by DML statements.

It defines how transactions are started and ended, as well as how a group of concurrently running transactions is managed.

Answer:

In linear serach when you perform one operation you reduce the size of the problem by one . But when you do one operation in binary search you reduce the size of the problem by half . It sounds efficient , isn't it

That's why time complexity of linear/sequential search is O(n) while binary search is O(logn).

Note - binary serach is applied only on sorted arrays.

I answered this question assuming that you have already read theory and algorithm of Binary as well as sequential serach .
