the correct answer choice woud be C. hope this helps :)
Explanation: Mountain ranges that form close to a subduction zone are likely to experience volcanic activity.
Hacks in real life are tricks to help solve a problem with a simple solution.
Say for example, add a pinch of salt to whip egg white faster.
The magnetic field is described mathematically as a vector field<span>. This vector field can be plotted directly as a set of many vectors drawn on a grid. Each vector points in the direction that a compass would point and has length dependent on the strength of the magnetic force. </span>
Explanation:
It is given that,
Velocity of the particle moving in straight line is :
![v(t)=t^2e^{-2t}\ m/s](https://tex.z-dn.net/?f=v%28t%29%3Dt%5E2e%5E%7B-2t%7D%5C%20m%2Fs)
We need to find the distance (x) traveled by the particle during the first t seconds. It is given by :
![x=\int\limits {v.dt}](https://tex.z-dn.net/?f=x%3D%5Cint%5Climits%20%7Bv.dt%7D)
![x=\int\limits {t^2e^{-2t}dt}](https://tex.z-dn.net/?f=x%3D%5Cint%5Climits%20%7Bt%5E2e%5E%7B-2t%7Ddt%7D)
Using by parts integration, we get the value of x as :
![x=\dfrac{-(2t^2+2t+1)e^{-2t}}{4}\ meters](https://tex.z-dn.net/?f=x%3D%5Cdfrac%7B-%282t%5E2%2B2t%2B1%29e%5E%7B-2t%7D%7D%7B4%7D%5C%20meters)
Hence, this is the required solution.
