Does a bullet touch the barrel?

Does a bullet touch the barrel? Bullets touch the inside of the gun’s barrel during normal operation. There’s rifling inside the barrel that’s supposed to impart spin on the bullet. So the barrel rubs grooves in the bullet (this is how CSI can match a bullet to a gun) but the softer bullet does little […]

Does carrying a heavy bag build muscle?

Does carrying a heavy bag build muscle? When you lift your backpack to place onto your back, you use your shoulder muscles (i.e. deltoids). Throughout the hike you will do this a number of times so make sure that you also have enough strength. Like the abdominal muscles, they stabilise the body and prevent fatigue […]

At what distance does gravity end?

At what distance does gravity end? Near the surface of the Earth (sea level), gravity decreases with height such that linear extrapolation would give zero gravity at a height of one half of the Earth’s radius – (9.8 m·s−2 per 3,200 km.) What is SI unit of weight? The SI unit of mass is the […]

Is absolute dating better than relative?

Is absolute dating better than relative? In relative dating, fossils are dated according to the depth at which they were buried. While in the absolute dating, isotopes of carbon are used for dating fossils. The absolute dating is more precise than relative dating because it tells the exact age of the fossils. What is the […]

Why are the first 3 years of life so important?

Why are the first 3 years of life so important? Recent research confirms that the first five years are particularly important for the development of the child’s brain, and the first three years are the most critical in shaping the child’s brain architecture. They have a direct impact on how children develop learning skills as […]

What is the weakest of the four fundamental forces?

What is the weakest of the four fundamental forces? Actually, gravity is the weakest of the four fundamental forces. Ordered from strongest to weakest, the forces are 1) the strong nuclear force, 2) the electromagnetic force, 3) the weak nuclear force, and 4) gravity. Because they both have mass, the two protons exert gravitational attraction […]
