What are physical properties Class 7? Physical properties include size, shape, colour and state (solid/liquid/gas) of a substance. Any change to the physical properties of a substance is called a physical change. Physical changes are usually reversible as no new substance is formed. It is the same substance but with changed physical properties. What are […]
Do sunspots affect weather?
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 the role of technology in healthcare?
What is the role of technology in healthcare? Our ability to store, share and analyze health information is directly tied to improved technology. The use of technology increases provider capabilities and patient access while improving the quality of life for some patients and saving the lives of others. What is the important role of science […]
Who disproved steady state theory?
Who disproved steady state theory? quasars Is the particular solution the steady state? The steady-state solution is the particular solution to the inhomogeneous differential equation of motion. It is determined by the driving force and is independent of the initial conditions of motion. What is steady state and transient? In general, nearly every process or […]
How much power does a water wheel generate?
How much power does a water wheel generate? Microhydropower systems usually generate up to 100 kilowatts of electricity. Most of the hydropower systems used by homeowners and small business owners, including farmers and ranchers, would qualify as microhydropower systems. Can a watermill generate electricity? Waterwheels are often overlooked for generating electricity but can be successfully […]
How do you show a force is conservative?
How do you show a force is conservative? Equivalently, a force is conservative if the work it does around any closed path is zero: Wclosed path=∮→Econs⋅d→r=0. What are conservative forces give two examples? Gravitational force is an example of a conservative force, while frictional force is an example of a non-conservative force. Other examples of […]
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 […]
