Do sunspots affect weather? A new study in the journal Science by a team of international of researchers led by the National Center for Atmospheric Research have found that the sunspot cycle has a big effect on the earth’s weather. When in the cycle does the maximum number of sunspots occur? Solar maximum or solar […]
What are the steps of design thinking?
What are the steps of design thinking? The five stages of Design Thinking, according to d. school, are as follows: Empathise, Define (the problem), Ideate, Prototype, and Test. Let’s take a closer look at the five different stages of Design Thinking. Who can use design thinking? Design thinking has been used to solve business problems […]
What is unit of stiffness?
What is unit of stiffness? In the International System of Units, stiffness is typically measured in newtons per meter ( ). In Imperial units, stiffness is typically measured in pounds(lbs) per inch. How do you increase the stiffness of a material? More generally, stiffness is calculated by F/Δ. To ↑ k, ↑ A and E […]
How many electrons are there in a neutral atom of?
How many electrons are there in a neutral atom of? A neutral atom is an atom where the charges of the electrons and the protons balance. Luckily, one electron has the same charge (with opposite sign) as a proton. Example: Carbon has 6 protons. The neutral Carbon atom has 6 electrons. Which two particles in […]
What is the role of second messenger in hormone action?
What is the role of second messenger in hormone action? Second messengers are molecules that relay signals received at receptors on the cell surface — such as the arrival of protein hormones, growth factors, etc. But in addition to their job as relay molecules, second messengers serve to greatly amplify the strength of the signal. […]
Are orbits stable?
Are orbits stable? Although the numerical simulations all indicate chaos in planetary orbits, in a qualitative sense the planetary orbits are stable—because the planets remain near their present orbits—over the lifetime of the sun. What happens if a satellite slows down? If the satellite slows down it would crash into the object it is orbiting. […]
What percentage of the block is submerged?
What to do if you are being spied on?
What are the six most common elements found in living things?
What are the six most common elements found in living things? The acronym CHNOPS, which stands for carbon, hydrogen, nitrogen, oxygen, phosphorus, sulfur, represents the six most important chemical elements whose covalent combinations make up most biological molecules on Earth. How many amino acids exist? 20 amino acids How many amino acids can humans not […]
What process produces oxygen?
What process produces oxygen? photosynthesis What role does cellular respiration play in the carbon cycle? Cellular respiration is the process by which organic sugars are broken down to produce energy. It plays a vital rolein the carbon cycle because it releasescarbon dioxide into the atmosphere. This means that cellular respirationcan be thought of as the […]
