Answer:
Answer: C
Explanation:
The closer the city is by the ocean, the cooler it will get because of the winds it is created from the ocean. Meanwhile, Atlanta is slightly away from the ocean but wont be as cool as the Tybee Island. So the heat will hit more to the city away from the ocean.
Answer:
Explanation:
<h3>a and b</h3>
We can use the following formula, from kinematics:
where is the final speed, is the initial speed, a is the acceleration and d the distance traveled.
Knowing that the final speed is zero, and the initial speed is
we obtain
Now, knowing that
then
<h3>c</h3>
We can use the following formula
so
<h3>d</h3>
Answer:
fem = -0.126 V
Explanation:
Faraday's law is
fem =
where the flow is
Ф = B . A = B A cos θ
bold letters indicate vectors.
In this case, the normal to the area is parallel to the magnetic field, so the angle is zero and the cos0 = 1
fem =
in this case they indicate that to carry the loop from outside to inside the field in Δt = 5 s, so we can change them by variations
fem =
let's calculate
fem = - 0.7 (0.9 -0) / 5
fem = -0.126 V
What are the statements? both of the objects do move attract and maybe that is the answer
Answer:
0.82 mm
Explanation:
The formula for calculation an bright fringe from the central maxima is given as:
so for the distance of the second-order fringe when wavelength = 745-nm can be calculated as:
where;
n = 2
= 745-nm
D = 1.0 m
d = 0.54 mm
substituting the parameters in the above equation; we have:
= 0.00276 m
= 2.76 × 10 ⁻³ m
The distance of the second order fringe when the wavelength = 660-nm is as follows:
= 1.94 × 10 ⁻³ m
So, the distance apart the two fringe can now be calculated as:
= 2.76 × 10 ⁻³ m - 1.94 × 10 ⁻³ m
= 10 ⁻³ (2.76 - 1.94)
= 10 ⁻³ (0.82)
= 0.82 × 10 ⁻³ m
= 0.82 × 10 ⁻³ m
= 0.82 mm
Thus, the distance apart the second-order fringes for these two wavelengths = 0.82 mm
