You are trapped on an alien world because you lost the keys to your spaceship and need to survive until help can arrive. Most of the plants and animals here look too much like CGI for you to want to eat, but from atop a 190 m cliff you spot a more viable game animal that you can hunt 150 m from the base of the cliff. All you have to hunt with is a Bow that can’t fire an arrow faster than 100 m/s. Select the velocity (speed and angle) with which you will shoot the animal.

the drift velocity is 1m/s under an external electric field electron drift slowly inside the conductor what is the relaxation time​

Answer» <html><body><p><strong>Explanation:</strong></p><p>In physics a drift velocity is the average velocity attained by charged particles, such as electrons, in a material due to an electric field. In general, an electron in a conductor will <a href="https://interviewquestions.tuteehub.com/tag/propagate-592982" style="font-weight:bold;" target="_blank" title="Click to know more about PROPAGATE">PROPAGATE</a> randomly at the Fermi velocity, resulting in an average velocity of zero. Applying an electric field adds to this random <a href="https://interviewquestions.tuteehub.com/tag/motion-1104108" style="font-weight:bold;" target="_blank" title="Click to know more about MOTION">MOTION</a> a small net flow in one direction; this is the drift.</p><p></p><p>Drift velocity is proportional to current. In a resistive material it is also proportional to the magnitude of an <a href="https://interviewquestions.tuteehub.com/tag/external-981194" style="font-weight:bold;" target="_blank" title="Click to know more about EXTERNAL">EXTERNAL</a> electric field. Thus Ohm's law can be explained in terms of drift velocity. The law's most elementary expression is:</p><p></p><p>{\displaystyle u=\mu E,}u=\mu E,</p><p>where u is drift velocity, μ is the material's electron mobility, and E is the electric field. In the MKS system these quantities' units are m/s, m2/(V·s), and V/m, respectively.</p><p></p><p>When a potential difference is applied across a conductor, <a href="https://interviewquestions.tuteehub.com/tag/free-465311" style="font-weight:bold;" target="_blank" title="Click to know more about FREE">FREE</a> electrons gain velocity in the direction opposite to the electric field between successive collisions (and lose velocity when traveling in the direction of the field), thus acquiring a velocity component in that direction in addition to its random <a href="https://interviewquestions.tuteehub.com/tag/thermal-706916" style="font-weight:bold;" target="_blank" title="Click to know more about THERMAL">THERMAL</a> velocity. As a result, there is a definite small drift velocity of electrons, which is superimposed on the random motion of free electrons. Due to this drift velocity, there is a net flow of electrons opposite to the direction of the field.</p></body></html>

What is time travel ? is it happened in real?​

Answer» <html><body><p><strong>Explanation:</strong></p><h3>Time travel is the concept of movement between certain points in time, analogous to movement between different points in space by an object or a person, typically with the use of a hypothetical device known as a time machine. Time travel is a widely recognized concept in philosophy and fiction. The idea of a time machine was popularized by H. G. <a href="https://interviewquestions.tuteehub.com/tag/wells-17822" style="font-weight:bold;" target="_blank" title="Click to know more about WELLS">WELLS</a>'s 1895 novel The Time Machine.[1]</h3><p></p><h3>It is uncertain if time travel to the past is physically possible.
