Answer:
the water level was shallow beach, then it rose to deep sea, then the water receded to a beach
Answer:
Diffraction equation applies in this case:
d*Sin x = m*wavelength, where d = spacing of lines, x = angle = 39.5°, m = order of maximum = 2
Substituting;
d* Sin 39.5 = 2*600*10^-9
d = (2*600*10^-9)/Sin 39.5 = 1.88656*10^-6 m
In 1 mm (or 0.001 m), the number of lines is given as;
Number of lines = 0.001/d = 0.001/(1.88656*10^-6) = 530.065 ≈ 530 lines
<span>magma and lava are the same general components, the only difference in the term is that magma has not been erupted. Once magma is erupted it is than redefined as lava. hope that helps</span>
Answer:
-4.769x
Explanation:
In order to develop the problem it is necessary to bring up the concepts related to Eyepiece or Focal Length of an ocular lens, i. e, the distance from the principal plane of the eyepiece where parallel rays of light converges to a single point. The equation is given by,
Where,
N= Near point
Magnification
Focal length
By replacing the values we can obtain that:
It is then possible to find the magnification of the telescope with the previous data found through
Answer:
The time taken for the sound wave to make the round trip is 0.16 s.
Explanation:
Given;
distance traveled by the sound wave, d = 120 m
bulk modulus of sea water, B = 2.3 x 10⁹ N/m²
density of sea water, ρ = 1022 kg
The speed of the wave is given by;
Speed is given by;
total distance of the round trip = 2 x 120m = 240 m
Time taken for the sound wave to make the round trip is given by;
Therefore, the time taken for the sound wave to make the round trip is 0.16 s.
