How do you stop pooling water? Identify where you have standing water in your yard. Use a shovel to dig a trench in that area that leads to a place where the water can more easily drain. Line the trench with pea gravel. Purchase a French drain pipe or simply get a plastic, flexible landscape […]

Does heat affect pipes? Whether hot or cold, extreme temperatures can have a serious effect on your plumbing. The expansion of pipes due to an abundance of heat can cause your pipes to burst, and, conversely, so can the freezing of water from severe cold temperatures. Does PVC expand with heat? Like all materials, PVC […]

Which singer has hit the highest note? Georgia Brown Which key is lower than C? In the major scale, there are eight notes going up the steps from bottom to top. These are the eight notes of the octave. On a C scale, the notes from low to high would be C, D, E, F, […]

Why are soap bubbles spherical? The attraction of the molecules, called surface tension, contracts the soap bubble to the smallest possible area. At the same time, the air inside the soap bubble presses against it. The bubble forms into a sphere because it can contain the largest contents with the smallest circumference. What do these […]

How many lobes is the human brain divided into? Each side of your brain contains four lobes. The frontal lobe is important for cognitive functions and control of voluntary movement or activity. The parietal lobe processes information about temperature, taste, touch and movement, while the occipital lobe is primarily responsible for vision. Who is known […]

What muscles are used to lift arm? Supraspinatus is responsible for beginning the upward motion of your arm. After about 15 degrees, the deltoid and trapezius muscles do the work. What muscle moves the arm across the body? The pectoralis major, latissimus dorsi, deltoid, and rotator cuff muscles connect to the humerus and move the […]

Why is a black body a perfect emitter? The name “black body” is given because it absorbs all colors of light. It is an ideal emitter: at every frequency, it emits as much or more thermal radiative energy as any other body at the same temperature. What is a black body BYJU’s? A black body […]

What color can Fireworks not be? Bright blue fireworks are far more challenging to produce than common colors like red, white, or green. Pyrotechnicians have been trying to produce brilliant blue fireworks for centuries, to no avail. Why are blue fireworks so rare? Too much or too little of the chemicals make significant changes in […]

Who is discovered Proton? Proton The quark content of a proton. The color assignment of individual quarks is arbitrary, but all three colors must be present. Forces between quarks are mediated by gluons. Classification Baryon Discovered Observed as H+ by Eugen Goldstein (1886). Identified in other nuclei (and named) by Ernest Rutherford (1917–1920). Who discovered […]

Why impact test is required? Impact Testing of metals is performed to determine the impact resistance or toughness of materials by calculating the amount of energy absorbed during fracture. The impact test is performed at various temperatures to uncover any effects on impact energy. What are the types of impact test? There are basically two […]
