<u>Alpha radiation</u> is a type of airborne particle that rapidly loses energy as it moves through the atmosphere, has weak penetrating strength, and can be prevented by clothing or a piece of paper.
<h3><u>Why does alpha radiation exist?</u></h3>
Two protons and two neutrons are bonded together to form an object resembling a helium-4 nucleus, which is what is known as an alpha particle, also known as an alpha ray, or alpha radiation. Although there are additional possibilities, they are often created during the alpha decay process.
The Greek letter, which begins the alphabet, is where the name "alpha particle" originates. Alpha is represented by the sign 2+. Net spin is zero for alpha particles. Alpha particles typically have a kinetic energy of around 5 MeV and a velocity in the area of 4% of the speed of light because of the mechanism of their generation in ordinary alpha radioactive decay.

B. saved lives. Mandatory seatbelt laws have saved lives.
So the equation would be 500 km ÷ 10 km/h = 50 (500÷10=50) Therefore your answer is 50
Answer:
If you are trying to reduce the cost of college, following strategies can save you the most money;
- Try and buy second hand recycled books instead of the new ones. This can cause you a tremendous amount of money. Borrowing from a senior is also a good choice.
- Look for TA ships where the salary is deducted from the annual fee of college and it eventually reduces the cost of tuition. A part time job can serve the same purpose.
- Transport is a big chunk of college cost along with residency if it is far from where you live. Try to find a room in sharing or affordable hostels closer to the college.
