Which of the following is true about antagonist drugs?

A particle is in uniform circular motion about the origin of an xy coordinate system, moving counter-clockwise with a period of

zepelin [54]

Answer: $\hat{v}=\frac{1}{\sqrt{2}}\hat{i}-\frac{1}{\sqrt{2}}\hat{j}$

Explanation:

Given

Time Period $T=6.5 s$

Position Vector $\vec{r}=6\hat{i}-6\hat{j}$

Since it is moving in a circular path therefore magnitude of position vector will give the radius of circular path

$|r|=\sqrt{6^2+6^2}$

$|r|=6\sqrt{2}$

$distance=velocity\times time$

$6\sqrt{2}=velocity\times 6.5$

$velocity=\frac{6\sqrt{2}}{6.5}$

$v=1.305$

this velocity is at angle of $\tan \theta =\frac{-6}{6}$

$\theta =-45^{\circ}$

velocity $\vec{v}=v\cos \theta +v\sin \theta$

$\vec{v}=1.305\cos (-45)+1.305\sin (-45)$

Therefore unit velocity vector

$\hat{v}=\frac{1}{\sqrt{2}}\hat{i}-\frac{1}{\sqrt{2}}\hat{j}$

Externally oriented planning is the third out of four discrete phases of the planning process, according to Gluck, Kaufman and Walleck’s

Read more: Externally oriented planning is one of the discrete phases of the planning process as described by Gluck, Kaufman and Walleck. It is a process used to search for untapped or emerging market opportunities while attempting to understand basic marketplace phenomena where in organizations begin to search for new ways to define and satisfy customer needs. It emphasizes on formal strategy formulation which include strategic thinking, understanding market elements that can be affected by rapid change drivers etc. with focus on consumers, competitors and suppliers. Here, lower level staff members may make decisions when financial and forecast based planning phases are ongoing.

4 states in at least one North American desert

Dmitry_Shevchenko [17]

<span>In relation to the Andes mountain, the Atacama desert is located to the west. It actually lies between the pacific ocean and the Andes mountain. The Atacama desert is one of the driest place on earth. It is a rainless pleatue located in Southern America. The Atacama desert covers almost a 1000 kilometers. The desert mainly consists of salt lakes, rocks and sand. This is a place where rain occurred numerous years ago and so it is considered a totally rainless place. There is every probability that the Atacama desert is the oldest desert present in the earth.
