Why does aluminum foil block WiFi signals? If you’ve ever thought of resorting to aluminum foil to redirect your home’s poor WiFi signal, it turns out you’re not actually that far off the mark. The foil, an electrical conductor, creates a barrier called a Faraday Cage around the phone, blocking the radio signals on which […]

Are landfills a problem? Landfill sites are pretty ugly. And it’s not just the sight of increasing piles of waste that’s the problem. The three most important problems with landfill are toxins, leachate and greenhouse gases. What are the negative effects of landfills? Almost two thirds of landfill waste is biodegradable. This waste rots and […]

What is the specific volume of water? The specific volume that correlates to that density is 0.00094 m3/kg. Notice that the average specific volume of blood is almost identical to that of water: 0.00100 m3/kg. What happens to volume when height is doubled? Step-by-step explanation: So, if R = constant, the volume changes in direct […]

How are vectors used in real life? Vectors have many real-life applications, including situations involving force or velocity. For example, consider the forces acting on a boat crossing a river. The boat’s motor generates a force in one direction, and the current of the river generates a force in another direction. Both forces are vectors. […]

Should my skull be bumpy? The skull is not perfectly round or smooth, so it is normal to feel slight bumps and ridges. However, a dent in the head, especially if it is new, requires a trip to the doctor to determine the cause. In this article, we examine the possible causes and symptoms of […]

Is a pH of 11 acidic or basic? Pure water has a neutral pH of 7. pH values lower than 7 are acidic, and pH values higher than 7 are alkaline (basic)….What does it mean for a solution to be acidic or basic (alkaline)? pH Value H+ Concentration Relative to Pure Water Example 11 0.000 […]

What type of goal setting challenge is Isaac facing? Isaac is facing distractions in achieving his ultimate goal or distractions is the goal setting challenge he is facing. What are the 3 components of a mad goal? MAD Goal: Measurable, Attainable, and Deadline-driven. What does measurable mean in mad? The M in MAD stands for […]

Why is it hard to find the ideal CO2 level If the light intensity? Why would it be hard to find the ideal CO level if the light intensity were very low? – It would be difficult to find the ideal CO2 level with a low light intensity because the plant will have a difficult […]

How can water be used to generate electricity at home? A new turbine uses running tap water to generate electricity at home. Vortical Tech LLC launched the first prototype of their turbine, which generates electricity whenever tap water is used. The hybrid Tesla turbine converts kinetic energy produced by the flow of water into electricity. […]

What is 1st order kinetics? First order kinetics occur when a constant proportion of the drug is eliminated per unit time. Rate of elimination is proportional to the amount of drug in the body. The higher the concentration, the greater the amount of drug eliminated per unit time. What is the difference between zero-order and […]
