How is gravitational potential calculated? Since the force required to lift it is equal to its weight, it follows that the gravitational potential energy is equal to its weight times the height to which it is lifted. PE = kg x 9.8 m/s2x m = joules.PE = lbs x ft = ft lb. What is...
Why is gravitational potential energy of a body always negative of the work done on a body? Explain about gravitational and elastic potential energy. What is the difference between potential energy and gravitational potential energy? What is the difference between gravitational potential ...
The formula is: ΔH = ΣΔH(products) - ΣΔH(reactants). How do we calculate the energy used in heating substances? The energy used to heat a substance can be calculated using the formula: Q = mcΔT, where Q is the heat energy in joules, m is the mass of the substance...
Enthalpyis a quantity in thermodynamics describing the heat that is transferred during chemical reactions. As heat, it can be thought of as one of the many forms of energy in physical science (e.g., gravitational potential energy, kinetic energy, sonic energy and so on). Bond enthalpyis the...
What Is Bond Enthalpy? Enthalpyis a quantity in thermodynamics describing the heat that is transferred during chemical reactions. As heat, it can be thought of as one of the many forms of energy in physical science (e.g., gravitational potential energy, kinetic energy, sonic energy and so on...
Calculate the potential energy of planet Earth at aphelion. What is the distance between the sun and Saturn? What is the circumference of Saturn, and how is it calculated? How far is 100 astronomical units? What is the orbital period of Venus? What is Jupiter's orbital period? How do orb...
Stress can be calculated formally using a simple algebraic equation that relates Young's modulus Y, the force per unit area F/A and the lengthwise deformation of the beam. You can find a steel beam calculator free online to help with the computation of t
With both measurements, scientists calculated a new value for the Hubble constant. However, the estimate came with a relatively large uncertainty of 14 percent, much more uncertain than the values calculated using the Hubble Space Telescope and the Planck satellite. ...
Dubbed "quintessence," this substance would fill the universe like a fluid and exhibit negative gravitational mass [source: NASA]. Other theories involve the possibilities that dark energy doesn't occur uniformly, or that our current theory of gravity is incorrect. Dark Matter in an Expanding ...
For each panel, urban porosity and average building side length are calculated from the building footprint data. Additionally, the DEM of each panel is analyzed to find the maximum slope and direction. We subsequently calculate the effective chord length in the direction of maximum slope in each...
