What is the probability of getting a doublet of even number? We know that the number of possible outcomes is 36. Thus, the probability of getting a doublet of an even number is =336=112. What is the probability of getting a sum of 14 when two dice are thrown simultaneously? The options for a sum […]
Does freezing require energy?
Does freezing require energy? Note that melting and vaporization are endothermic processes in that they absorb or require energy, while freezing and condensation are exothermic process as they release energy. What takes more energy freezing or boiling? It takes just as long for water to freeze as it takes for ice to melt, if the […]
Can coefficient of friction be above 1?
Can coefficient of friction be above 1? The coefficient of friction is dimensionless and it does not have any unit. It is a scalar, meaning the direction of the force does not affect the physical quantity. The coefficient of friction depends on the objects that are causing friction. The value is usually between 0 and […]

What are transverse and longitudinal waves give examples?
What are transverse and longitudinal waves give examples? Examples of transverse waves include vibrations on a string and ripples on the surface of water. We can make a horizontal transverse wave by moving the slinky vertically up and down. In a longitudinal wave the particles are displaced parallel to the direction the wave travels. Can […]
What happens if you mix ammonia with water?
What happens if you mix ammonia with water? Ammonia gas dissolves easily in water to form ammonium hydroxide, a caustic solution and weak base. Ammonia gas is easily compressed and forms a clear liquid under pressure. What are some signs of ammonia stress in a tank? Signs of Ammonia stress Lethargy. Loss of appetite. Hovering […]
What are the 4 stages of water cycle?
What are the 4 stages of water cycle? So how can we understand this magical process called the water cycle? There are four main parts to the water cycle: Evaporation, Convection, Precipitation and Collection. Evaporation is when the sun heats up water in rivers or lakes or the ocean and turns it into vapour or […]
