What does a hollow point do to a body? But what does this have to do with hollow points? Well, it’s simple. Since a hollow-point bullet expands when it enters soft tissue, it creates a larger wound channel inside the target, increasing the chances that incapacitating damage will be done. Can you survive a hollow […]

What are the four properties of water? The main properties of water are its polarity, cohesion, adhesion, surface tension, high specific heat, and evaporative cooling. A water molecule is slightly charged on both ends. What are physical and chemical properties of water? We have seen the physical and chemical properties of water and understood its […]

Is 10cc equal to 10 ml? 1ml is equal in volume measurement to 1 cc. equal to 1ml= 1 cc or cm3; So, 10 ml is close to 10 cm3 or 10cc. Is 1cc the same as 1 ml? What’s the difference between a cubic centimeter (cc) and milliliter (mL)? These are the same measurement; […]

At what point the velocity of the projectile is maximum and minimum during its flight? Answer. In a Trajectory the projectile would have Minimum velocity at Trajectory point ( At the maximum height ) . & Possess Maximum velocity at initial projection point (due to initial acceleration) & at the point when projectile hits the […]

Is flow rate the same as velocity? Rate of flow, or simply flow, is the quantity of water, for example, that flows in a tube or other medium, in an interval of time. Examples: 2 kg of water per second, or 100 cubric meters of air per minute. Velocity is how fast the water, air […]

What is the difference between polar and spherical coordinates? Spherical coordinates define the position of a point by three coordinates rho ( ), theta ( ) and phi ( ). is the distance from the origin (similar to in polar coordinates), is the same as the angle in polar coordinates and is the angle between […]

Can humans grow tails? Many believe that human ancestors had and used some form of a tail. Over time as a species, however, we evolved past the need for such an organ, which is why the majority of humans no longer grow them. Most humans grow a tail in the womb, which disappears by eight […]

Does the 9th planet exist? The ninth planet was no more. At the same time, the discovery of these objects uncovered a major new lead in the search for a hidden planet. It turns out that Sedna is not moving in the way everyone expected – tracing elliptical rings around the Sun, from within the […]

How do you know if an appliance is grounded? You can usually tell whether your electrical system is grounded by checking your power outlets. If they accept plugs with three prongs, your system should have three wires, one of which is a grounding wire. Similarly, an appliance designed to be grounded is equipped with a […]
