Kelly should position the ruler such that the border of the ruler would be against the thing. The parallax error occurs whenever the distance of objects is measured to be less or more than the initial length of this same object.Whenever a viewer watches an element at such an oblique angle corresponding towards the scale, it appeared together in changed or modified location on some kind of scale.

Thus the approach above is right.

Answer from: memester74

To minimize parallax, she should Place the ruler in such a way that the edge is against the object.

Explanation:

When the measurement of the length of an object is lesser or greater than the original length of that object, then the Parallax error happens. The main reason for the occurrence of this type of error is due to the wrong position of eyes to the measurement marking angle. On a scale, an object appears at a different or modified position,When a person views an object at an oblique angle corresponding to the scale. This is where the parallax error comes in existence.

This error can be minimized by placing the device used for measurement on the edge. This will result in making the same level for the device for measurement and the object that is to be measured.

It won't lose or gain electrons if it's a covalent bond it shares the electrons with another atom or atoms. if it is an ionic bond it will lose the 3 electrons on the outer shell and become a positively charged ion. credit goes to @sunshinebaby of answers.yahoo.com.

Answer: it will take 4.36 seconds to reach her average velocity 10.69 miles/hour.explanation: we have equation of motion $s=ut+\frac{1}{2} at^2$ ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/s $s=0*t+\frac{1}{2} *2.18*t^2$ $s=1.09t^2[/ 2equating equation 1 and 2 [tex]4.75t = 1.09t^2\\ \\ t=4.36 seconds.$ so it will take 4.36 seconds to reach her average velocity 10.69 miles/hour.

Ablock of mass m = 2.5 kg is attached to a spring with spring constant k = 740 n/m. it is initially at rest on an inclined plane that is at an angle of theta= 26 with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is uk = 0.17. in the initial position, where the spring is compressed by a distance of d = 0.16 m, the mass is at its lowest position and the spring is compressed the maximum amount. take the initial gravitational energy of the block as zero. the block's initial mechanical energy is 9.472 j.b. if the spring pushes the block up the incline, what distance l in meters will the block travel before coming to rest? the spring remains attached to both the block and the fixed wall throughout its motion.
