The diagram shows a transistor
which explains whether boron or arsenic is the dopant most
likely used in the semiconductor layer marked with +?
this layer is the controller of an npn transistor, so it
could include boron.
this layer is the emitter of an npn transistor, so it could
include arsenic.
this layer is the controller of a pnp transistor, so it could
include arsenic.
this layer is the emitter of a pnp transistor, so it could
include boron.

Ineed extreme for task 2. my student number is 571721. many to whoever solves this correctly, im in debt to you.

According to the tide table below what time of day will the highest tide occur?

Arotating space station is said to create “artificial gravity”—a loosely-defined term used for an acceleration that would be crudely similar to gravity. the outer wall of the rotating space station would become a floor for the astronauts, and centripetal acceleration supplied by the floor would allow astronauts to exercise and maintain muscle and bone strength more naturally than in non-rotating space environments. if the space station is 200 m in diameter, what angular velocity would produce an “artificial gravity” of 9.80 m/s^{2} 2 at the rim?
