Answer: when an object begins to fall its potential energy decreases and it’s kinetic energy increases, potential energy is equal to kinetic energy because a decrease in potential energy is exactly equal to the increase in kinetic energy.
It will eventually wear down the rock due to hydraulic action and etc
Bag of feathers because it weighs the least
Answer:
B. Zero
Explanation:
Here the number of downloads between minute 14 and minute 15 is 3000. The number does not increase or decrease so the slope is zero.
The slope of line between two points (x₁, y₁) and (x₂, y₂) is given by
![m=\frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
Here,
![m=\frac{30-30}{15-14}\\\Rightarrow m=\frac{0}{1}=0](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B30-30%7D%7B15-14%7D%5C%5C%5CRightarrow%20m%3D%5Cfrac%7B0%7D%7B1%7D%3D0)
The slope of a function is given by the differential of the function.
Answer:
For which country do we locate the most earthquakes? Japan. The whole country is in a very active seismic area, and they have the densest seismic network in the world, so they are able to record many earthquakes.
