A space vehicle approaches a space station in orbit. The intent of the engineers is to have the vehicle slowly approach, reducing velocity, until a docking maneuver is completed and the vehicle is attached to the station.
How does the total momentum of the docked vehicle and station compare to the momentum of each object before the
docking maneuver?
40
greater momentum
same momentum
less momentum

Does this organism still meet the definition of a eukaryote ? why or why not?

Suppose an objects initial velocity is 10m/s and it’s final velocity is 4 m/s. mass is constant. what can best be concluded about the object based in the work-energy theorem

Antireflective coatings on solar cells are often made by applying a thin film of silicon nitride (sinx), which has an index of refractive of 1.2, on the top of the silicon solar cell, which has a refractive index of about 3.5. however, the sun emits radiation of various wavelengths which the solar cell absorbs, and the antireflective coating can only absolutely minimize the reflection of one of these wavelengths. the coating thickness is chosen to reduce the reflection of green/yellow light (e = 2.2 ev), which is the most intense color in the solar spectrum (shown below). which of the following coatings would minimize reflection of green/yellow light? the answer is 820 nm how? what is the angular width of the central maximum of an electron traveling at 2 x 108 m/s going through a single slit of width 1 mm.
