To develop this problem it is necessary to apply the Rayleigh Criterion (Angular resolution)criterion. This conceptos describes the ability of any image-forming device such as an optical or radio telescope, a microscope, a camera, or an eye, to distinguish small details of an object, thereby making it a major determinant of image resolution. By definition is defined as:
Where,
= Wavelength
d = Width of the slit
= Angular resolution
Through the arc length we can find the radius, which would be given according to the length and angle previously described.
The radius of the beam on the moon is
Relacing
Replacing with our values we have that,
Therefore the diameter of the beam on the moon is
Hence, the diameter of the beam when it reaches the moon is 7361.82m
Answer:
<h2>0.64 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
m is the mass
v is the volume
From the question
m = 45 g
v = 70 mL
We have
We have the final answer as
<h3>0.64 g/mL</h3>
Hope this helps you
Answer:
Convection and Radiation mechanisms carry most of the heat
Explanation:
This is because Convection proceeds strongy as heated air rises from the hot element while Radiation is also strong, although the material of the cooking pots will how effective it is.
Answer: The electromagnetic waves reach Earth, while the mechanical waves do not.
Explanation:
From the moment it leaves Terry's hand ... all the way up and then all the way down ... until the moment the ball hits the ground, its acceleration is 9.8 m/s^2 downward. That's the acceleration of gravity (on Earth), and gravity is the only force acting on the ball.
By the way ... Terry needs to control his rage and go get a job as a pitcher for Major League Baseball. That 100 m/s of his is more than double the speed that professional pitchers typically deliver !
