In contrast, a transparent material allows you to clearly see the objects on the other side. Frosted glass is translucent, and regular glass is transparent. Why is […]

What happens to your body after plane crash? When there is an explosion that tears a big hole into the plane and the cabin’s little bubble of pressure is suddenly burst, something called “explosive decompression” takes place. Basically, the pressure difference comes rushing at your body so fast that it tears your body apart. Do […]

How far does a GFCI have to be from a sink? six feet Do you need a ground for a GFCI to work? A GFCI does not need a ground wire in order to trip properly. A GFCI simply trips when a fault is detected on the neutral wire. An ungrounded outlet will not trip […]

What are 5 examples of a compound? Compounds Examples Water – Formula: H2O = Hydrogen2 + Oxygen. Hydrogen Peroxide – Formula: H2O2 = Hydrogen2 + Oxygen2 Salt – Formula: NaCl = Sodium + Chlorine. Baking Soda – Formula: NaHCO3 = Sodium + Hydrogen + Carbon + Oxygen3 Octane – Formula: C8H18 = Carbon8 + Hydrogen18 […]

What happens when an atom gains a proton? Adding or removing protons from the nucleus changes the charge of the nucleus and changes that atom’s atomic number. So, adding or removing protons from the nucleus changes what element that atom is! For example, adding a proton to the nucleus of an atom of hydrogen creates […]

Can brain waves be amplified? Physicists have shown for the first time that electrical signals in the human brain are amplified by noise. In many complex systems, weak periodic signals can be strengthened by noise. Does listening to alpha waves do anything? What are the benefits of alpha waves? You may be wondering why alpha […]

Does copper react with oxygen at room temperature? Answer: At high T , you may get a state where Cu(I) oxide is stabler, but in the presence of excess Oxygen, it will be oxidized to Cu(II) oxide. 0.150 g of copper reacts with oxygen form 0.188 g of copper oxide. Why do copper vessels lose […]

What to do if electricity keeps tripping? Switch off and unplug the appliance or fitting and try again. If you don’t know what might be causing the fuse box to trip, take a look at the switches and work out which fuse is tripping alongside the RCD. This will allow you to identify the room […]

What is the maximum heart rate for a 20 year old person? For example, for a 20-year-old person, the estimated maximum age-related heart rate would be calculated as 220 – 20 years = 200 beats per minute (bpm). What is the target heart rate for a 25 year old? Ideal heart rate for exercise Target […]
