What do you want me to answer here?
Explanation:
C i’m pretty sure cuz the rest of them happen after
Answer:
. = 2574.08
Explanation:
given data
magnitude V1 = 80
magnitude V2 = 50
angle a = -37°
solution
= 80 k
= 50 cos{37} i - 50sin{37} k
so that here . is
. = 80 k . ( 50 cos{37} i - 50sin{37} k )
. = 80 k . ( 38.270 i + 32.176 k )
. = 2574.08
Answer:
Explanation:
In this case we will use the Bohr Atomic model.
We have that:
We can calculate the centripetal force using the coulomb formula that states:
Where K=
and r is the distance.
Now we can say:
The mass of the electron is = Kg
The charge magnitud of an electron and proton are=
Substituting what we have:
[/tex]
so:
"Oscilloscope" can be used to show the shape of a sound wave
Hope this helps!
