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 […]

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 […]

Why are the first 3 years of life so important?

What are the similarities and differences between the somatic nervous system and the autonomic nervous system?

What are the similarities and differences between the somatic nervous system and the autonomic nervous system? The somatic nervous system has sensory and motor pathways, whereas the autonomic nervous system only has motor pathways.

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 […]
