I don't understand at all, please help if you're able! Part A. Find the direction and of the vector r (arrow above, pointing right) [?° ccw from the +x-axis
Part B. Find the magnitude of the vector r (arrow) [? m]
Part C. Suppose that rx and ry are doubled, find the direction and the magnitude of the new vector r (arrow)'
Part D. r' = ? m

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.

Awater-filled u-tube manometer is used to measure the pressure inside a tank that contains air. the water level in the u-tube on the side that connects to the tank is 5 ft above the base of the tank. the water level in the other side of the u-tube (which is open to the atmosphere) is 2 ft above the base. determine the pressure within the tank.
