Explanation:
Orbital speed= 2pi x radius / time period
=2pi x 1.5x10^11 / 365.25
=2.58x10^9m/day
<u>Answer</u>
5.9 × 10¹⁴ Hz
<u>Explanation</u>
The wave equation states that;
V = λf
Where V ⇒ velocity of light
λ ⇒ wavelength
f ⇒ frequency
V = λf
3.0×10⁸ = 510×10⁻⁹ × f
Dividing both sides by 510×10⁻⁹,
f = (3.0×10⁸) / (510×10⁻⁹)
= 5.8824 × 10¹⁴ Hz
Answer to the nearest tenth, 5.9 × 10¹⁴ Hz.
if it is a displacement time graph, It will increase upwards in a straight line.
If it is a velocity time graph it will remain as a straight horizontal line
If it is an acceleration time graph there will be a horizontal straight line at 0

Answer:
Yes
Explanation:
Certain types of weathering are more common in certain environments than others.
This is very true.
- Weathering is the physical disintegration and chemical decomposition of rocks to form sediments and soils.
- Different forms of weathering are dictated by their geographies on the earth surface.
- Ice or frost wedging is only possible in temperate or polar regions of the world.
- Exfoliation is pronounced around the tropical region as series of thermal expansion and contraction is involved.
- Alternate freezing and thawing which expands cracks is also a geographical phenomenon.
