At a wedding reception, you notice a small boy who looks like his mass is about 25 kg running part way across the dance floor, then sliding on his knees until he stops. if the kinetic coefficient of friction between the boy's pants and the floor is .15, what is the frictional force acting on him as he slides?

Question 9: use your experiences from questions 6, 7, and 8 to you state a general rule for identifying the three declination ranges given the observer's latitude.

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.
