A lady moves a suitcase of mass 22.3 kg with frictionless wheels across a horizontal floor by pulling on a cord attached to the suitcase making an angle of 0 = 46.4 degrees to the horizontal, as shown in the diagram. If the lady pulls the cord with a force of 15.1 N, what is the magnitude of the acceleration of the suitcase, in units of m/s2

Aneutron and a proton combine to form a nucleus. why does the mass of the nucleus differ from the sum of the masses of the individual nucleons?

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.
