Answer:
The distance between the two slits is 1.2mm.
Explanation:
The physicist Thomas Young establishes, through its double slit experiment, a relationship between the interference (constructive or destructive) of a wave, the separation between the slits, the distance between the two slits to the screen and the wavelength.
(1)
Where 
is the distance between two adjacent maxima, L is the distance of the screen from the slits, 
is the wavelength and d is the separation between the slits.
If light pass through two slits a diffraction pattern in a screen will be gotten, at which each bright region corresponds to a crest, a dark region to a trough, as consequence of constructive interference and destructive interference in different points of its propagation to the screen.
Therefore, d can be isolated from equation 1.
(2)
Notice that it is necessary to express L and in units of millimeters.
⇒ 
⇒ 
Hence, the distance between the two slits is 1.2mm.
Answer:
1. Count the atoms of each element in the reactants and the products.
2. Use coefficients; place them in front of the compounds as needed.
Explanation:
A balanced force is upon it because balanced means both sides are equal so they cancel each other out, while unbalanced means one side is weaker/stronger than the other and in this case its in a state of rest so the net force would be equal/balanced.
Answer:
a) 1273.23 A/m^2
b) 7.19*10^-5 m/s
c) 236881.7 Ohms
Explanation:
(a) To find the current density you use the following formula:
I: current in the wire
A: cross area of the wire
r: radius of the wire
(b) The electron drift speed is given by:
n: number of conduction electrons per m^3
q: charge of the electron = 1.6*10^-19C
The number of free electrons is calculated by using:
Next, you replace the values of the parameters in the equation for vd:
(c) The conductivity is given by:
You first calculate R:
Next, replace for sigma:
