Q:

How far does a bullet travel in water?

A:

The distance a bullet travels through water depends on the shape and initial velocity of the round. Generally, the faster a round is moving, the less distance it travels underwater. Likewise, blunt-tip bullets retain more velocity underwater than their pointed counterparts.

Pointed-tip rounds with a muzzle velocity of 1,000 feet per second travel between 2 and 15 feet, although they are slowed enough that they are non-fatal beyond 3 feet. Similarly, pointed-tip rounds fired at 2,500, 2,800 or 3,000 feet per second will fragment in the first three feet, thus having a negligible travel distance. Blunt-tip rounds with a muzzle velocity between 900 and 2,000 feet per second can travel up to 8 feet and still be fatal; beyond that they are slowed.

    What is Isaac Newton's theory of gravity?

    A:

    Isaac Newton's theory of gravity states that every particle in the universe attracts every other particle with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. The law is represented as: F=G (m1m2)/R.

    What is the formula for acceleration?

    A:

    The formula for acceleration is given as a = (v2 - v1) / (t2 - t1), where "a" denotes the acceleration, "v2" indicates the final velocity, "v1" represents the initial velocity and "t2 - t1" is the time interval between the final and initial velocities. The SI unit for acceleration is meters per second squared (m/s2), while the British imperial unit is feet per second squared (ft/s2).

    How is a toilet paper dispenser a wheel and axle?

    A:

    A toilet paper dispenser is an example of a wheel and axle. The rod that supports the roll of toilet paper serves as the axle, and the toilet paper roll serves as the wheel. Like all wheel and axle machines, the toilet paper rotates concentrically around the cylindrical holder, which is fastened in place.
