How do we know the nucleus is positive? Rutherford deduced that the atomic nucleus was positively charged because the alpha particles that he fired at the metal foils were positively charged, and like charges repel. In Rutherford’s experiments most of the alpha particles passed straight through the foil without being deflected. Is a nucleus positive? […]
Does high spin speed damage clothes?
Does high spin speed damage clothes? Myth: Higher spin speeds will ruin your clothes! Busted: No! Higher spin speeds will not ruin your clothes when you use the appropriate settings. High spin speeds are ideal for cottons, bulky items such as towels and bedding and denim. Can you rinse clothes in a spin dryer? You […]

Is eating no meat healthy?
Is eating no meat healthy? The health factor And people who don’t eat meat — vegetarians — generally eat fewer calories and less fat, weigh less, and have a lower risk of heart disease than nonvegetarians do. Even reducing meat intake has a protective effect. Will I get sick if I eat meat after being […]

What does the atomic mass tell you?
What does the atomic mass tell you? The atomic mass tells us the weight of protons and neutrons. How do you know how many electrons there are surrounding the nucleus of a particular atom? Why isn’t the atomic mass always a whole number? Atomic mass is never an integer number for several reasons: The atomic […]

What is the primary difference between the concepts of health and wellness?
What is the primary difference between the concepts of health and wellness? In understanding the difference between health and wellness, in short, health is a state of being, whereas wellness is the state of living a healthy lifestyle (3). Health refers to physical, mental, and social well-being; wellness aims to enhance well-being. How do health […]
Which is better PNP or NPN transistor?
Which is better PNP or NPN transistor? A NPN transistor has electrons as majority charge carriers whereas the PNP transistor has holes as majority charge carrier. The mobility of electrons is better than mobility of holes. mobility of electrons is more than hole,so as a result npn transistor are faster than pnp that’s why they […]
What is going to happen in 2099?
What is going to happen in 2099? Artificial intelligence will move its influence beyond Earth’s limits to the entire Solar System, and then it will move on to other galaxies. Stars, planets, and meteors will be transformed into a structured matter capable of sustaining life. By 2099, machines will be capable of building computers the […]
