Calculate the value of the g at a hight h = 4R from surface earth ( take g = 10m/s) at the earth
- A ray of light from the sun strikes the windshield of a car at an angle of incidence of 36.0° and refracts at an angle of 24.0°. If the initial light had a wavelength of 630 nm, determine the wavelength of the light after it has refracted.
At a distance of 55 million light years from Earth, and with a mass equal to 2.4e12 solar masses, calculate the angular diameter of that black hole's event horizon as viewed from the Earth. (express your answer in arcseconds)
-link all the relevant physics ideas to each other and to the context to integrate them into your explanation of how or why the physics relates to tidal heating.
-The key physics ideas tidal heating should include:
Newton’s law of gravitation and tidal forces
Centre mass of orbiting systems
Satellite motion (Kepler’s laws)
Synchronous orbits and how they form over time
Orbital resonance of Jupiter’s moons and the implications of this for tidal heating
Average energy emission per hydrogen atom in hydrogen fusion = 6.55 MeV
The luminosity of the Sun = 3.86 ×10^26 J/S
