A student wanting to measure voltage E1 of a battery finds no null point possible. He then diminishes R to 10 Ω and is able to locate the null point on the last segment of the potentiometer. Find the resistance of the potentiometer wire and potential drop per unit length across the wire in the second case.

Thus a circle which has radius r will have 2 * pi * r "points" on its circumference. The total number of points is pi * R^2. Thus you should give the circle r a probability equal to (2 * pi * r) / (pi * R^2) = 2 * r/R^2. This is much easier to understand and more intuitive, but it's not quite as mathematically sound.. The magnitude of a particle's acceleration moving in a circular motion is given by, a = ω 2 r. This being so, radius r = 25 cm and frequency = 2 revolutions per second. We remember, angular speed, ω = 2 π f. ⇒ ω = 2 π × 2 = 4 π r a d / sec. Radius = 25cm = 25 100 m = 0.25 m. Still, Centripetal acceleration,.

Answer. The missing length is the circumference. Using the knowledge that the diameter is 4.3m on the diagram and knowing that C = πd, we can calculate the circumference. With a little thinking we can easily figure out that, C = π x 4.3m = 13.51m (to 2 decimal places). The missing length is 13.51m..

This calculator computes the values of typical circle parameters such as radius, diameter, circumference, and area, ... It can also be defined as a curve traced by a point where the distance from a given point remains constant as the point.

Then you rotate this circle, so that the point lands on a surface of a sphere. First let's declare two angles, theta (polar, 0..2Pi) and phi (azimuthal, -Pi/2..Pi/2). There are zillions of conventions, but I'm fond of the one where the 360 rotation goes around the polar axis (longitude), and then the other dictates the distance from the equator (latitude).

VIDEO ANSWER:So what we see for this problem is that we have a wheel and it's rotating. We have the origin right here. This is our radius. And then this is the point p, and then we have This is also the radius right here. And then we have some value of theta, and this can be the point. And then from here we have this, which is the the rod of length l attached to a point p. \[T=\dfrac{2\pi R}{v}\], where v is the velocity of rotation. In a uniform circular motion, speed will be constant but the direction will be different at each point of the circle. Frequency is the number of revolutions completed by the particle in a unit time. In a uniform circular motion, the velocity is always tangent to the path of the object.. Since 2 is your radius, you have to sq it. 2 X 2 = 4 X pi to get your area of the full circle, 12.56. Then the hint it gives you is "Remember, a quarter of the circle is missing." So you divide 12.56 by 4 and get 3.14. Then you subract 3.14 from 12.56 to get 9.42, but it says to round to the nearest tenth in which you would round down to 9.4. .

This is according to the formula: 2πr (where r is radius of a circle). Now for displacement we know that this is a vector quantity and we need to observe the initial and final position of the body. Whenever the initial and final position of a body is same ,as in this case, the displacement will be zero. Chuck Britton. T. required for the particle to complete one circle is given by. T = 2 π R v. So the path on the circle travelled by the particle is. s = t T. ⇒ s = π R 2 v 2 π R v. ⇒ s = 1 4. Hence, the particle has travelled one fourth of the total circle.
