The Schwarzschild radius of the sun can be calculated using Rs= (2GM)/c2. Substitute in the mass of the sun (M=21030), the speed of light (c=3108), and the univer...
As the potential difference across the filament lamp increases the current across the lamp also increases due to Ohm's law.The increase in current flow also causes the lamp to heat up which causes the res...
Newtons first law states that is an object is moving it will continue to do so in a constant direction and uniform velocity unless acted upon by an external force.Newtons second law states that the change...
Radioactive isotopes are useful as they can be detected. Detecting these waves can help us find problems within the body and come up with prognoses. An example of this is PET scans. These use substances t...
The luminosity of our Sun could be derived by the Stefan-Boltzmann, otherwise known as Luminosity law. It says the total energy produced by a unit surface per unit time area (power per unit area) is: Answered by Denislav G. • Physics tutor1630 Views
