A1.2 kg mass in placed on the end of a 1.4 m string. one end of the string is fixed, creating a simple pendulum. the mass is pulled to the side so that the string makes an angle of 8◦ with respect to the vertical and released from point a at t = 0. (a) what is the angular frequency of the system? (b) what is the maximum angular velocity of the pendulum? (c) what is the maximum linear speed of the mass? (d) at which point is the magnitude of the angular acceleration greatest? i. b ii. c iii. d

Abody of weight 60 kg is standing in a lift the lift going upward with a uniform velocity of 4.9 metre per second slows down and stops in two seconds then apparent weight of the body during the slow down process is

In the sport of parasailing, a person is attached to a rope being pulled by a boat while hanging from a parachute-like sail. a rider is towed at a constant speed by a rope that is at an angle of 15 ∘ from horizontal. the tension in the rope is 1900 n. the force of the sail on the rider is 30∘ from horizontal. what is the weight of the rider? express your answer with the appropriate units.

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.
