Answer:
The correct answer is in the x-axis direction, where the distance travelled is 1.0 cm and the surface is 8 
.
Explanation:
The electrical resistance is lower when the contact surface is larger and the length is shorter.
An electrical resistance is an opposition to the flow of electric current through a conductor. For a given conductor, the resistance is given by the following formula:
R = ρ * 
Where:
R: Electrical resistance.
ρ: Resistivity of the material.
l: Length.
S: Surface of the conductor.
Thus, the direction in which the electrical resistance is lower is when the distance is minimum and the area is greater.
Have a nice day!
Answer:
Explanation:
If a be grating element
a = 1 x 10⁻² / 11000
= .0909 x 10⁻⁵
= 909 x 10⁻⁹ m
for first order maxima , the condition is
a sinθ = λ where λ is wavelength
909 x 10⁻⁹ sin 49.67 = λ₁
λ₁ = 692.95 nm .
λ₂ = 909 x 10⁻⁹ sin 50.65
= 702.91 nm
λ₃ = 909 x 10⁻⁹ sin 52.06
= 716.88 nm
λ₄ = 909 x 10⁻⁹ sin 52.89
= 724.90 nm
692.95 nm , 702.91 nm , 716.88 nm , 724.90 nm .
Hello =D
This problem is about cinematic
So
V = 45 mi/h
t = 2 h
Then
V= X/t
X = V*t
Then
X = (45)*(2)
X = 90 mi
Best regards
Metalloids are all solid at room temperature. Some metalloids, such as silicon and germanium, can act as electrical conductors under the right conditions, thus they are called semi-conductors. Silicon for example appears lustrous, but is not malleable or ductile (it is brittle - a characteristic of some nonmetals).
