Answer:
We know that the electronic charge is 1.6 E-19 coulombs
Therefore 1 coulomb of charge contains 1.6 E19 electrons
A charge of 16.7 E6 coulombs therefore contains
N = 16.7 E6 * 1.6 * E-19 = 2.67 E-12 electrons
Also, the charge on the proton equals that on the electron
Answer:
d₂ = 1.466 m
Explanation:
In this case we must use the rotational equilibrium equations
Στ = 0
τ = F r
we must set a reference system, we use with origin at the easel B and an axis parallel to the plank
, we will use that the counterclockwise ratio is positive
+ W d₁ - w_cat d₂ = 0
d₂ = W / w d₁
d₂ = M /m d₁
d₂ = 5.00 /2.9 0.850
d₂ = 1.466 m
Answer
D. move a small magnet back and forth within a section of the coiled wire.
Explanation:
i put that for the test and i got it right
Answer:
The object starts away from the origin and then moves toward the origin at a constant velocity. Next, it stops for one second. Finally, it moves away from the origin at a greater constant velocity.
