Answer:
velocity relative to the ground = 2.54 m/s
Explanation:
given data
still water Vx = 2.30 m/s
across a steam Vy = 1.20 m/s
solution
we get here first velocity relative to the ground is express as
velocity = ...............1
put here value and we get
velocity =
velocity = 2.54 m/s
B. Free electrons are concentrated in the P-type material and holes form in the N-type material.
C. The negative terminal of the source of voltage is connected to the N-type material within a reverse-biased setup.
D. Only a small current will flow through the diode in the forward-biased setup.
Answer:
The first one.
If the road becomes wet or crowded, you should slow down and increase your following distance.
If the road becomes wet or crowded, you should slow down and increase your following distance. This is important because wet roads reduce tire traction and increase the risk of sliding and losing control. By slowing down and increasing your following distance, you give yourself more time to react and stop if necessary.

A. nuclei
B. nucleons
C. electrons
D. protons
E. neutrons
The correct option is C.
Atoms are neutral; they contain the same number of protons as electrons. By definition, an ion is an electrically charged particle produced by either removing electrons from a neutral atom to give a positive ion or adding electrons to a neutral atom to give a negative ion.
An isotope is one of two or more forms of the same chemical element. Different isotopes of an element have the same number of protons in the nucleus, giving them the same atomic number, but a different number of neutrons giving each elemental isotope a different atomic weight.
