(a) In figure point A is in the fourth quadrant In the fourth quadrant X is positive and Y is negative .So the coordinate of A is (4,−3) In figure point B is in the third quadrant .In the third quadrant X is negative and Y is also negative.So the coordinate of B is (−3,−1)
$$\displaystyle△{x}={x}{2}−{x}{1}$$
$$\displaystyle△{x}=−{3}−{4}=−{7}$$
$$\displaystyle△{y}={y}{2}−{y}{1}$$
$$\displaystyle△{y}=−{1}−{\left(−{3}\right)}=−{1}+{3}={2}$$
(b) In figure point A is in the first quadrant In the first quadrant X is positive and Y is also positive .So the coordinate of A is (2,1) In figure point B is in the second quadrant .In the second quadrant X is negative and Y is also positive .So the coordinate of B is (−4,3)
$$\displaystyle△{x}={x}{2}-{x}{1}$$
$$\displaystyle△{x}=−{4}−{2}=−{6}$$
$$\displaystyle△{y}={y}{2}−{y}{1}$$
$$\displaystyle△{y}={3}−{1}={2}$$

The drawing shows two strings that have the same lengthand the same linear density. The left end of each string is attached to a wall,while the right end passes over a pulley and is connected to objects of different weights(Wa and Wb). Different standing waves are set up on each string, but theirfrequencies are the same. If $$\displaystyle{W}_{{a}}={44}\ {N}$$, what is $$\displaystyle{W}_{{b}}$$.

Oscar chose A as the correct answer. How did he get that answer?
A pair of forces with equal magnitudes, opposite directions,and different lines of action is called a "couple". When acouple acts on a rigid object, the couple produces a torque thatdoes not depend on the location of the axis. The drawing shows acouple acting on a tire wrench, each force being perpendicular tothe wrench. Determine an expression for the torque produced by thecouple when the axis is perpendicular to the tired and passesthrough (a) point A, (b) point B, and (c) point C. Express youranswers in terms of the magnitude F of the force and the length Lof the wrench
The photograph shows a workman struggling to keep a stack of boxes balanced on a dolly. The man's right foot is on the axle of the dolly. Assuming that the boxes are identical, which one creates the greatest torque with respect to the axle?
a) the highest box
b) the lowest box
c) the box farthest to the right
d) the box farthest to the left
The figure shows 3 crates being pushed over a concrete floor by a horizontal force f of magnitude 440N. The masses of the cratesare $$\displaystyle{m}_{{1}}={30}$$ kg, $$\displaystyle{m}_{{2}}={10}$$ kg, and $$\displaystyle{m}_{{3}}={20}$$ kg.The coefficient of kineticfriction between the floor and each of the crates is 0.7. a) what is the magnitude $$\displaystyle{F}_{{{32}}}$$ of the force on crate 3 from crate 2? b) If the crates then slide onto a polished floor, where the coefficientof kinetic friction is less than 0.700, is magnitude PSKF_{32}ZSL more than,less than, or the same as it was when the coeffient was 0.700?
