Two balls undergo inelastic collision. the y-momentum after the collision is 98 kilogram meters/second, and the x-momentum after the collision is 100 kilogram meters/second. what is the magnitude of the resultant momentum after the collision?

The slope of a good speed time indicates ? a. velocity b. acceleration c. direction d. speed

Will you chech and finish these for me, because i am stumped with them.

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.
