In which glass of water did the salt dissolve faster? Salt does dissolve quicker in room temperature water than in cold water. In fact, you can take that even further, and say that any solid substance that can dissolve in water, will dissolve quicker in hot water than room temperature water. What are the two […]

How do you know if an electron will be ejected? The number of electrons ejected can be determined by measuring the current between the wire and plate. In equation form, the photon energyis E = hf, where E is the energy of a photon of frequency f and h is Planck’s constant. What is difference […]

Why is it called a shield volcano? Illustrated Volcano Glossary Shield volcanoes are volcanoes that mainly erupt fluid (usually basaltic) lava flows that are able to travel over long distances and thus construct over time broad, gentle slopes. They are called shield volcanoes, because they resemble the shape of a warriors’shield. How dangerous is a […]

How do you calculate cooling capacity of a heat exchanger? Using the energy equation of Q = ṁ x Cp x ΔT we can calculate the cooling capacity. We add 273.15K to the celcius to convert it to units of Kelvin. The Specific heat capacity (Cp) is measured in units of kJ per kg per […]

Does anyone know anyone? ‘Anybody’ is a third person singular form and takes -s in the present simple tense. That’s why the question form requires -s and ‘Does anybody’ is correct. The same would apply to ‘Does anyone’, ‘Does anything’ etc. What is the difference of do and are? We use does and is with […]

What is mechanical energy give two examples? A moving car possesses mechanical energy due to its motion (kinetic energy). A moving baseball possesses mechanical energy due to both its high speed (kinetic energy) and its vertical position above the ground (gravitational potential energy). How many types of mechanical energy explain it? two types Does a […]

Which chemical equation is unbalanced? According to the law of conservation of, the number of atoms in the products of a chemical reaction must be balanced with the number of atoms in the reactants. The chemical equation for the formation of ammonia is unbalanced. Which is an example of chemical change quizlet? Define a chemical […]

What describes the length of a vector? Which describes the length vector? It is in the direction of the current. What is the length of unit basis? A unit vector is a vector with length/magnitude 1. A basis is a set of vectors that span the vector space, and the set of vectors are linearly […]

In which light photosynthesis takes place faster? white light Do plants grow better in white light or blue light? White light is actually made by combining other colors on the spectrum such as red, green, and blue. Therefore white light will actually be much more beneficial for the photosynthesis process than yellow light. What color […]

What is the process that converts physical energy? Transduction: It is the biological process in which any external physical stimuli is received and relayed from one part of the body to another part. During this process energy i.e stimuli is converted into electro chemical stimuli. What is the first step in sensation for some sensory […]
