How do power lines kill birds? Birds can be injured or killed with they collide with electric lines in mid-flight. Although birds of all sizes and types collide with wires, their behavior and body type put them more at risk for line collisions. Can a human hang from a power line? Hanging from a power […]

Which best describes the difference between radiation and conduction? Convection is the transfer of energy by movement of a medium, whereas radiation is the transfer of energy by, well, thermal radiation. Conduction also requires a medium, but, again, it is a fundamentally different mechanism than either convection or radiation; in this case it is the […]

What are examples of loud sounds? Loud sound has a high volume while soft sound has a low volume. Banging of a hammer and a car’s horn are examples of loud sounds while playing of a piano and sound of blowing wind are examples of soft sounds. What are the examples of soft sounds? Soft […]

What are 2 types of speed? There are two types of speed: result-speed and task-speed. What are 3 types of speed? In general, there are three types of speed limits: absolute, presumed and basic. What are 4 types of speed limits? In California, there are four major Speed Laws: Basic, Prima Facie, Maximum, and Minimum. […]

How did you separate the components of salt water solution? For example, water can be separated from salt solution by simple distillation. This method works because water has a much lower boiling point than salt. When the solution is heated, the water evaporates. It is then cooled and condensed into a separate container. What technique […]

Is kicking a ball an example of third law of motion? Newton’s Third Law Of motion Newtons third law states that “for every action, there is an equal and opposite reaction.” In soccer, when you kick the soccer ball you will feel the force of the kick back into your leg. You wont feel the […]

Which Colour deviates more and why? All the colors of white light have different wavelengths and their deviation is also different. Also, the violet color has the least wavelength. Therefore when it travels from one medium to another, then it has the maximum value of the angle of incidence and the violet color will deviate […]

What is the change of state when wax melts? Melting of wax, by itself, involves a change of state from solid to liquid. When the physical state of a substance changes, no new products are formed. Hence, it is a physical change. What state was the wax in before it was heated? solid What will […]

What type of energy is a boy walking in the street? kinetic energy What happen if you hammer a nail in a wood? Answer. When you use a hammer to pound a nail into a board, you transfer kinetic energy to the hammer and the hammer transfers that kinetic energy to the nail. Any form […]

What are the 3 types of wells? There are three types of private drinking water wells. Dug/Bored wells are holes in the ground dug by shovel or backhoe. Driven wells are constructed by driving pipe into the ground. Drilled wells are constructed by percussion or rotary-drilling machines. Does rain fill your well? While your well […]
