What makes a roller coaster go faster? The kinetic energy that makes a rollercoaster car move at speed comes from the potential energy the car gained when it was hauled to the top of the very first hill on the ride. The further they go down the hill, the faster they go, and the more […]
How we can measure shear rigidity?
How we can measure shear rigidity? Modulus of rigidity or shear modulus is the rate of change of unit shear stress with respect to unit shear strain for the condition of pure shear within the proportional limit. Modulus of rigidity formula is G = E/(2(1+v)), and modulus of rigidity is G, elastic modulus is E […]
When should states be capitalized?
When should states be capitalized? You capitalize “state” only when it follows the name of the state, as in “New York State is also called the Empire State,” or when it’s part of a traditional name for a state, like “Empire State” or “Lone Star State.” When it precedes the name of the state, don’t […]

What is hands on activity in science? Hands-on science is defined mainly as any instructional approach involving activity and direct experience with natural […]
What is the formula for capacitance of a capacitor?
What is the formula for capacitance of a capacitor? The generalised equation for the capacitance of a parallel plate capacitor is given as: C = ε(A/d) where ε represents the absolute permittivity of the dielectric material being used. How can you increase the capacitance of a parallel plate capacitor? The capacitance of a set of […]
How many hours of sun does a north-facing garden get?
How many hours of sun does a north-facing garden get? You’ll get quite a bit at the height of summer, I should think about 7 hrs a day ime, central England latitude — more if you’re further north. Obviously at the ends of the day (morning, early evening. Good aspect for a conservatory (won’t get […]
What is the relationship between heat work and internal energy?
What is the relationship between heat work and internal energy? The relationship between the internal energy of a system and its heat and work exchange with the surroundings is: E = q + w (The form of work will be restricted to gaseous, PV-type for this discussion.) Interestingly, both q and w are not state […]
How can water be used to generate electricity at home?
How can water be used to generate electricity at home? A new turbine uses running tap water to generate electricity at home. Vortical Tech LLC launched the first prototype of their turbine, which generates electricity whenever tap water is used. The hybrid Tesla turbine converts kinetic energy produced by the flow of water into electricity. […]
