Why can electric field lines never cross? Electric field lines cannot cross. This is because they are, by definition, a line of constant potential. The equipotential at a given point in space can only have a single value. If lines for two different values of the potential were to cross, then they would no longer […]

What is the formula for FG?
When waves pass through an opening or around a corner the waves bend as they pass the corners?
When waves pass through an opening or around a corner the waves bend as they pass the corners? Refraction is the change in direction of waves that occurs when waves travel from one medium to another. Refraction is always accompanied by a wavelength and speed change. Diffraction is the bending of waves around obstacles and […]
Why does the pressure exerted by gas not depend on the type of gas?
Why does the pressure exerted by gas not depend on the type of gas? Explanation: the pressure exerted by a gas does not depend on the type of the gas because pressure is a physical force its has not chemical composition. So, pressure depends upon the numbers of molecules of the gas because gas molecules […]
What are the different types of observation explain with examples?
What are the different types of observation explain with examples? When it comes to observational research, you have three different types of methodologies: controlled observations, naturalistic observations, and participant observations. Let’s quickly look at what each type of observation includes, how they differ, and the strengths and weaknesses of each type of observation. What are […]
What is the warmest layer of the atmosphere?
What is the warmest layer of the atmosphere? The thermosphere is often considered the “hot layer” because it contains the warmest temperatures in the atmosphere. What flew in the thermosphere before it was grounded? E. The thermosphere contains a layer of charged particles called the ionospherewhich makes communication by radio wavespossible and is home to […]
What makes water drinkable?
What makes water drinkable? Filtration – The clear water on top passes through filters composed of sand, gravel and charcoal to remove dissolved particles such as dust, parasites, bacteria, viruses and chemicals. Disinfection – Chlorine or chloramine is added to kill parasites, bacteria, viruses and germs. How do you sanitize water? Boil water, if you […]
What is a real life example of a single replacement reaction?
What is a real life example of a single replacement reaction? An example of a single replacement reaction occurs when potassium (K) reacts with water (H2O). A colorless solid compound named potassium hydroxide (KOH) forms, and hydrogen gas (H2) is set free. The equation for the reaction is: 2K + 2H2O → 2KOH + H. […]
