A8.10×103 ‑kg car is travelling at 25.8 m/s when the driver decides to exit the freeway by going up a ramp. after coasting 383 m along the exit ramp, the car's speed is 12.6 m/s, and it is ℎ=12.5 m above the freeway. what is the magnitude of the average drag force exerted on the car?

Hydrogen atoms are excited by a laser to the =4n=4 state and then allowed to emit. what is the maximum number of distinct emission spectral lines (lines of different wavelengths) that can be observed from this system? 8 6 2 7 4 5 1 3 calculate the wavelength of the 4⟶14⟶1 transition. =λ=

(there could be more than one correct choice.) a) increase the charge on the plates b) decrease the poten5al between the plates c) increase the potential between the plates d) introduce a dielectric material between the plates e) decrease the separation between the plates

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