Answer: water freezes inside a rock, causing it to break
Weathering is a natural process in which the rocks break into pieces or sediments by the action of wind, water and chemical agents. Frost wedging is a physical weathering process. It occurs in an area where temperature fluctuations occurs due to change in the climatic conditions. This occurs due to rapid heating and cooling. The rocks lying in a cold environment, the water residing in the rocks gets freezed. The water in ice form that is solid form acquire more space than in liquid form, therefore, the developed ice will affect the physical structure of the rock. The formation of ice results in the development of break or crack in the rock typically in the shape of a wedge and thus the phenomena is called as frost wedging.
Hence, frost wedging happens when water freezes inside a rock, causing it to break.
Answer:
I don't really know much about the whole stars thing, but I've written a lot of paragraphs in science
Explanation:
Remember:
- A paragraph should be in CER formation: Claim (hypothesis/discovery), Evidence, and Reasoning
- Your reasoning should never start with I believe or I think, your reasoning and evidence are 100% fact based
- The actual hypothesis should only be 1-2 sentences and be straight to the point
Include:
- for your hypothesis, keywords relating to your subject, I'm assuming for your topic you should include things like marking, telescope, stars, etc.
- why you believe your hypothesis is true
- so use prior knowledge to justify your hypothesis
Answer:
F = 19.375 x 10^-6 N
Explanation:
This problem can be solved by applying Coulomb's Law, which lets us determine the force between two electrically charged particles.
It is defined as
F = (ke * q1 * q2)/ r^2
Where,
ke = is Coulomb's constant ≈ 9×10^9 N⋅m^2⋅C^−2
q1 = 5.0 x 10^-8 C
q2 = 1.0 x 10^-7 C
r = 5 ft = 1,524 m
F = (9×10^9 N⋅m^2⋅C^−2)*(5.0 x 10^-8 C)*(1.0 x 10^-7 C)/ ((1,524 m)^2)
F = (9×10^9 N⋅m^2⋅C^−2)*(5.0 x 10^-8 C)*(1.0 x 10^-7 C)/ ((1,524 m)^2)
F = 19.375 x 10^-6 N
D: both weight and displacement are vector quantities
vector quantities have both magnitude and direction while scalar quantities only have magnitudes
