The radial acceleration of a body a distance <em>R</em> from the center of a circular path and with period <em>T</em> has magnitude <em>a</em> such that
<em>a</em> = 4 <em>π </em>² <em>R</em> / <em>T </em>²
The given period is
<em>T</em> = 365.3 days ≈ 3.156 x 10⁷ s
(i.e. multiply the number of days by 24 hours/day and 3600 seconds/hour)
So the Earth's radial acceleration is
<em>a</em> = 4 <em>π</em> ² (1.5 x 10¹¹ m) / (3.156 x 10⁷ s)²
<em>a</em> ≈ 0.0059 m/s²
Answer:
The difference in atomic mass between the two isotopes is 1.002780942 atomic mass unit.
Explanation:
For an isotope-I (heavier)
Mass of an isotope-I=M
Number of neutrons = n+1
Number of protons = p
For an isotope-II
Mass of an isotope-II=M'
Number of neutrons = n
Number of protons = p
Difference in binding energy:

B.E-B.E'=5.4810 MeV
A) heterogeneous mixture & I believe B?
I know A is correct though
Answer:
B
Explanation:
The Southern Hemisphere reflects a tremendous amount of radiation during the December solstice.
Answer:
C. strike-slip fault
Explanation:
The scientist must have observed a strike- slip fault.
A fault is an evidence of brittle deformation of the crust in the presence of applied stress on earth materials. Here, the earth material is the rock subjected to tension.
Where a fault occurs, there must have been movement between two blocks of rocks. The direction of movement helps us to delineate the fault type.
- When two blocks moves past each other horizontally, it is a strike-slip fault like rubbing your palms together.
- When a block moves in the direction of the dip, it forms a dip-slip fault which results in a fault-block mountain characterized by graben and horst systems.
Option A, Plateau is a table landform usually a mountain with flat peak.
Option B is a bowl shaped stratigraphic pattern in which the youngest sequence is at the core of the strata or a fold.
So, the most fitting option is C, a strike-slip fault.
