Answer:
TRUE
Explanation:
Cinder cones are usually characterized by the cone-shaped, steep sloping volcanoes, and are typically comprised of pyroclastic materials. These volcanoes have a slope of about 30° to 40° and have a summit at the mouth of the volcano. They are of short height and are found mostly adjacent to the bigger volcanoes such as strato-volcanoes and central vent volcano. They erupt at a much faster rate compared to the long-lived ones.
Thus, the above-given statement is True.
Eₖ = √1/2 mv²
Eₖ/v² = 1/2 m
2Eₖ/v² = m
mgh = 1/2 mv²
gh = 1/2 v²
2gh = v²
v = √2gh
= √2 × 10 N/kg × 2 m
= 6.324 ms⁻¹
m = 9.8/(6424)²
= 9.8/39.993
= 0.245 g
I am not sure if it's correct.
i transposed for m in the first equation then to find the velocity I combined the potential and kinetic energy equation. there was no mass because velocity doesn't depend on the mass
Then I used earth's gravitational field strength (g) 10 N/kg and the 2 m was the height provided in the question
you can try working and see if you get the same
Answer:D&E
Explanation:
Hope this helps :) please mark branilst
Ocean acidification is the ongoing decrease in the pH of the Earth's oceans, caused by the uptake of carbon dioxide from the atmosphere.
1.51 is the partial pressure of gas Y. as At 300 K, the volume of the flask that contains a gaseous mixture of two gases, X and Y, is 20 L. If the total pressure of the container is 2 atm and 0.1.
<h3>What is
gaseous mixture?</h3>
The gaseous combinations that are properly considered in this book are blends of different ingredients that may or may not vary outside of certain bounds.
These gases often belong to the category of "fuel gases," and each gas is any of a number of fuels that are gaseous at normal temperatures and pressure.
Thus, 1.51 is the correct answer.
