The speed of a bobsled is increasing because it has an acceleration of 2.0 m/s2. at a given instant in time, the forces resisting the motion, including kinetic friction and air resistance, total 450 n. the mass of the bobsled and its riders is 255 kg. (a) what is the magnitude of the force propelling the bobsled forward

The earth remains in orbit around the sun due to the force of gravity. how does the force of gravity exerted by the sun on the earth compare to the force of gravity exerted by the earth on the sun?

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.
