Three forces act on a hot-air balloon: the lift force from the hot air is 5020 N; the weight of the balloon and load is 4050 N; the leftward force from the wind is 950 N. Draw a free-body diagram of the balloon and find the resultant force.

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.

If a balloon is taken outside on a very cold day, what will occur?

What sort of waves exhibit the doppler effect?
