Answer:
E = 5.03 10⁻³ N / C
Explanation:
For this exercise we can use Gauss's law
Ф = E. dA = /ε₀
Where as a Gaussian surface we select a cylinder
Ф= E A = q_{int} /ε₀
Let's use the concept of surface charge density
σ = q / A
q = σ A
E A = σ A /ε₀
E = sig /ε₀
Since the plate is non-conductive, the fux does not flow through the plate
With this equation the electric field does not depend on the distance, so the field at 1 cm
E = 45 10³ N/C
σ = E ε₀
σ = 45 10³ 8.85 10⁻¹²
σ = 3.98 10⁻¹⁰ C / m²
As the point where the field is requested is very far from the plate we can not ignore the finite size of it
At r = 15 m the plate has a very small size, so let's calculate the field as created by a point load at this distance
E = k q / r²
The plate area is
A = L L
A = 0.75²
A = 0.5625 m²
q = σ A
q = 3.98 10⁻¹⁰ 0.5625
q = 1.26 10⁻¹⁰ C
Let's calculate
E = 8.99 10⁹ 1.26 10⁻¹⁰ / 15²
E = 5.03 10⁻³ N / C
The answer is option C) The car experienced negative acceleration with velocity in the positive direction.
It is the heat required to raise the temperature of the unit mass of a given substance by a given amount (usually one degree).
For us to understand the missing item that would complete beta decay reaction, we need to achieve in depth understanding of chemical formulas and nuclear symbols. Next is to have great comprehension of the following points:
<span>1.) Neutron in nucleus breaks down and changes into a proton.
2) Then it emits an electron, as well as an anti-neutrino which go into space.
3) Lastly, atomic number continuously goes UP while mass number remains unchanged.</span>
