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 […]

What does a hollow point do to a body?
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?
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 […]
Why is the pulley less than 100% efficient?
Why is the pulley less than 100% efficient? It is important to remember that NO pulley system is 100% efficient. This is due to friction of the ropes against the pulley wheels and the friction of the bearings of the pulley wheels as they rotate. This type of pulley arrangement will always have the same […]

How do I calculate weight of pipe?
How do I calculate weight of pipe? So now we have to multiply this volume by CS pipe density (7850Kg/m3) to get the actual weight of 1 m of pipe length. So Metal weight of 1 m of Pipe length=0.0036004565*7850=28.26358356 Kg. To calculate the pipe weight for more lengths simply multiply the above value with […]
Are most stars redshifted or Blueshifted?
Are most stars redshifted or Blueshifted? Are most stars redshifted or blueshifted? Most stars are affected by redshift. This tells us that the universe is expanding and the galaxies with high gravity that are close are blue shifted while the rest spread apart and are redshifted because of the expansion. Is redshift moving away or […]
How do you know if an appliance is grounded?
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 […]
