A uniform meter stick with a mass of 180 g is supported horizontally by two vertical strings, one at the 0-cm mark (with tension T1) and the other at the 80-cm mark (with tension T2). A small pentagonal object of mass = 50g is placed at the 60cm mark. Required:
a. Draw a picture showing all forces acting on the stick (do not forget the weight of the meter stick).
b. Calculate the tensions in the strings at the 0-cm and 80-cm mark by choosing the pivot point at T1.

Give your knowledge of these things in your paper, you will compare and contrast analog and digital signals to determine which is more reliable for encoding and transmitting information. you’ll compare these features: signal shape numerical values for signal measurements amount of data that can be transmitted energy requirements privacy and security (ability of the signal to be encoded in a secret code) clarity of signal in the space provided, write down what you already know about any of these features. if you’re not sure, write down questions you might have about the features.

Which pair of quantities includes one quantity that increases as the other decreases during simple harmonic motion?

When is a current produced? when the terminals of an electrochemical cell are connected by a wire if the electric circuit is opened in an electrochemical cell if the electrolyte is removed from an electrochemical cell when the electrodes are reversed in an electrochemical cell
