Answer:
D. A radio telescope (hope this helps)
Explanation:
Answer:
No, the apparent weight will be different.
Explanation:
Although the mass is still the same, the apparent weight will be different. This is because of the centripetal acceleration caused by the Earth's rotation. At the poles, there is no centripetal acceleration. The closer you get to the equator, the larger the centripetal acceleration becomes, and the lower the apparent weight becomes.
To solve this problem it is necessary to apply the concepts related to the condition of path difference for destructive interference between the two reflected waves from the top and bottom of a surface.
Mathematically this expression can be described under the equation
Where
n = Refractive index
t = Thickness
In terms of the wavelength the path difference of the reflected waves can be described as
Where
\lambda = Wavelenght
Equation the two equations we have that
Our values are given as
Wavelength of light
Therefore the minimum thickness of the oil for destructive interference to occur is approximately 34.0 nm
-- Bob covered a distance of (32m + 45m) = 77 meters.
-- His displacement is the straight-line distance and direction
from his starting point to his ending point.
The straight-line distance is
D = √(32² + 45²)
D = √(1,024 + 2,025)
D = √3,049 = 55.22 meters
The direction is the angle whose tangent is (32/45) south of east.
tan⁻¹(32/45) = tan⁻¹(0.7111...) = 35.42° south of east.
D. Must be implemented using a computer.
It is possible to make scientific models without computers and/or other technology.
