The biggest thing you're doing wrong is ignoring the units
when you're working with the quantities.
Now let's look at the rest of the problem:
The formula you used is correct:
Net flux through the surface = (net charge inside) / ε₀
and ε₀ = 8.85 x 10⁻¹² farad/meter.
What's the net charge inside the surface in this problem ?
It's (5.85 x 10⁷ electrons) x (the charge on each electron)
= (5.85 x 10⁷ electrons) x (-1.6 x 10⁻¹⁹ coulomb/electron)
= -9.36 x 10⁻¹² coulomb .
Finally, (net charge inside) / ε₀
= (-9.36 x 10⁻¹² coulomb) / (8.85 x 10⁻¹² farad/meter)
= -1.058 newton-m²/coulomb .
The sign and the significant figures in your answer are correct, so
we can see that you know what you're doing. The only thing left is
the order of magnitude. You most likely took one of the negative
exponents and made it positive. You got an answer that's 10²² too
small. Big deal. You could claim "that's close", and see whether you
can convince a teacher.
Crystalline Solids.
In theses solids the molecules or ions are arranged in a pattern.
The smallest repeating structure is called a unit cell.Thses unit cells combine to from crystal latttices.
Salt and minerals are such an example.
Thses are also called true solids
Answer:
10 seconds
Explanation:
If the height is modeled by the function , then the seconds it takes to reach the water (when the height equals 0) is modeled by the following.
The one that <span>invented the clamping mechanism that made elevators significantly safer was: Elijah Graves Otis
Before his invention, Elevators could only be used to carry out things with small weight, since most elevators couldn't sustain heavy objects and often fall. After his invention, a stronger restraint for the elevator is formed and it became safe enough to carry out a several people.</span>
Answer:400m
Explanation: x=20⋅10+ 4.10^2/2 =400m
