Light has a wavelength of 340.0 nm and a frequency of 5.403 x 1014 Hz when traveling through a certain substance. What substance from Table 26.1 could this be? Show your calculation

The image shows the positions of a car on a roller coaster track. arrange the cars in order based on their gravitational potential energy. begin with the lowest potential energy and end with the highest.

The sun’s mass is 2.0×10^ 30 kg, its radius is 7.0×10 5 km, and it has a rotational period of approximately 28 days. if the sun should collapse into a white dwarf of radius 3.5×10 3 km, what would its period be if no mass were ejected and a sphere of uniform density can model the sun both before and after?

The energy produced as a result of this flow of electrons from atom to atom is called
