On the device below, when the hanging bob (mass 440 grams) is pulled to the point...
Static Equilibrium Lab: Wheel and Axle If you wanted to lift something heavy using this device, would you have the heavy object connected to the larger disc and then pull one the smaller disc, or vice-versa? Why? What would be the effect of using this device on the speed that the object lifts? That is, if you pulled your string at a speed of 10 cm/s, would the object lift 10 cm/s, or would it lift faster or slower? Activity...
how to find abs error of time 25 ? help me fill out the blanks and show calculation of F centripetal... Centripetal Force and Acceleration For a body in motion to ch force on a body is in the sa acceleration in that the speed i direction opposite to that of the velocit undergoing negative acceleration. In thes speed, not direction. In this lab we lo wdy in motion to change either its speed or direction, a force is required....
use UNITS for all final answers no collaboration, no talking to each other is allowed you can use your book and your calculator, but nothing else! (1) 10 points Three identical charges (q- -4.8 pC) lie along a circle of radius 2.0 m at angles of 30°, 150°, and 270°, as shown in the figure. (a) What is the resultant electric field at the center of the circle (magnitude and orientation)? (b) What is the electric potential at the center...
question 4-7 4. Travelling Waves and Their Characteristics A rope wave travels in the positive x -direction. You are also told that the speed of the wave is 1000 cm/s, its frequency is 200 Hz, and that the wave is subject to the following initial conditions: at x 0 and t = 0: y =-1 cm, and, at x = 0 and t : ar = +20 cm/s (this is the velocity of the point on the rope at horizontal...
please give me answers to all the questions and i would really appreciate that thank you 6. -0 points My Notes O Ask Your Teache A 10.1 kg object oscillates at the end of a vertical spring that has a spring constant of 2.20 x 104 N/m. The effect of air resistance is represented by the damping coefficient b = 3.00 N-s/m (a) Calculate the frequency of the dampened oscillation. H2 (b) By what percentage does the amplitude of the...
