How gravity is created? Earth’s gravity comes from all its mass. All its mass makes a combined gravitational pull on all the mass in your body. You exert the same gravitational force on Earth that it does on you. But because Earth is so much more massive than you, your force doesn’t really have an […]
Why is the sodium potassium pump so important to the human body?
Why is the sodium potassium pump so important to the human body? In the kidneys the Na-K pump helps to maintain sodium and potassium balance in our body. It also plays a key role in maintaining blood pressure and controls cardiac contractions. What human body system depends on the sodium potassium pump? nervous system Why […]
What is the effective resistance between A and D?
What is the effective resistance between A and D? D=5Ω+10Ω+5Ω=20Ω What is the effective resistance in the given circuit? The effective resistance of a circuit containing resistances in parallel is smaller than any of the individual resistances. For example : R1=2Ω and R2=3Ω ∴ Effective resistance Rp1=R11+R21. Maximum effective resistance will be when all the […]

What is the half-life of AU 198?
What is the half-life of AU 198? 2.697 days How do you calculate the half-life of sodium 24? Notice that the time period between each of the yellow crosses is 15 hours. This tells us that the count rate of Sodium-24 halves every 15 hours. In other words, the activity of Sodium-24 is halved every […]
