So Hey whatsup guys today at engraver beats we are gonna talk about that how to create android apps without codding
yes, android apps can be created without codding but with some limitations but then also you can create an awesome app and also can do most of the things and even through that you can earn money from ads same like a website.So first of all there are these websites through which you can android apps
1.
https://thunkable.com/#/ (Ads allowed medium)
2.
https://www.kodular.io/ (Ads allowed all types Best)
3.
http://appinventor.mit.edu/explore/ (Ads not allowed low)
4.
https://appybuilder.com/ (Ads allowed Higher than medium)
These all are best app creating platform without codding and if you want to know how to create apps by using above sites you can go on youtube and watch just searching any above and what you want to make The apps created from above platform can also be published on playstore now some channels which can help you for learning building apps are on youtube
1.walya express (search on youtube)
2.7 star media (search on youtube)
3. The developer 2.0 (Search on youtube)
Best channels for learning developing apps using website
Now lets tell you about all platform seperately and what are there advantages and disadvantages
Lets go
Thunkable
Thunkable is one of the oldest and best app creators without codding they provide a good customer support through there own thunkable community where you can ask any problem facing in thunkable or any new thing you want to know and also they have admob banner,intestional ads feature but not any other if you want to add other ads you can use extension there is also one more version of thunkable which is thunkable modern above which i tell you about was thunkable classic with new modern thu

Hi Guys this is Ayush and you are at Engraver Beats and today gonna talk about Radioactivity. Is really radioactivity harmful,how many types of radioactivity are there and there properties So LETS GET STARTED
What is Radioactivity ?
=> Radioactivity is the nuclear phenomenon of spontaneous emission of alpha,beta,gamma radiations from the nuclei of atoms during there decay.
Henry Becquerel discovered the phenomenon of radioactivity in 1896 .At starting these rays were known as Becquerel rays .
The substances which disintegrate by the spontaneous emission of radiations are called the radioactive substances.e.g. uranium,radium.polonium,actinium etc.
The symbol of radioactivity is in below image wherever there is this type of sign do not go there
There are basically three types of radiations alpha,beta,gamma and gamma is the most harmful among three so lets know in deep
Alpha Particles
Alpha particles consist of two protons and two neutrons.It is same as a doubly ionised helium atom i.e., a helium nucleus containing two protons and two neutrons.It is represented as He++.The mass of alpha particles is four times the mass of protons i.e., 6.68 * 10^-27 kg and it has positive charge of +3.2*10^-19 c and its specific charge is 4.79*10^7 c kg^-1 .The speed of alpha particles is 10^7 m/s. Alpha particles strongly ionises the gas through which it passes. AS alpha particles are positively charge they are deflected by magnetic and electric fields. It also affect the photographic plate and cause fluorescence material on striking the fluorescent material. These destroy the living cell and cause biological damage . Alpha particles can be stopped from thin micca foils
Beta Particles
Beta particles are fats moving electrons and its mass is 9.1*10^-31 kg. Its charge is -1.6*10^-19 c and specific charge is 1.76*10-11 c/kg.
