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,.

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. .

A particle is moving round **a circle of radius** 10cm. The angular speed is **2** rad s-1. Find the (linear) speed. We want the **radius** in metres, which is 0.1m . ... the **radius** of the **circle** the particle **moves** in is 0.5 m and the angle at A is 45 degrees. Find the angular speed of P. The weight is 2g (W= mg), where g is the acceleration due to gravity.
