Answer:
-3.2 ×1.6 ×10^-19C
Explanation:
Number of proton = 6
Number of electron = 8
To determine the quantity of the charge, we would first find the difference between the number of
protons and electrons. Then multiply the difference by charge 1.6 x 10 -19 C to determine the charge on the object.
Difference between proton and electron is elementary charge
Elementary charge = proton - electron
= 6 - 8
Elementary charge = -2e
Recall, charge (q) = 1.6 ×10^-19C
1e = 1.6 ×10^-19C
Magnitude of the charge of object = -2× (1.6 ×10^-19C)
Magnitude of the charge of object = -3.2 ×1.6 ×10^-19C
Answer:
A that the answer I think I'm not tryna do u bad thi
Explanation:
but try it
If the echo (the reflected sound) reaches your ear less than about
0.1 second after the original sound, your brain doesn't separate them,
and you're not aware of the echo even though it's there.
If the echo comes from, say, a wall, 0.1 second means you'd have to be
about 17 meters away from the wall. If you're closer than that, then the
echo reaches you in less than 0.1 second and you're not aware of it.
A. 30 meters . . .
No. You hear that echo easily
B. you're standing within range of both sounds . . .
No. You hear that echo easily, if you're at least 17 meters from the wall.
C. less than 0.1 second later . . .
That's it. The echo is there but your brain doesn't know it.
D. 21.5 meters
No. You hear that echo easily.
