The resistance, R to the motion of a car is partially constant and partly varies as the square of the speed, v. When the car is moving at 30km/h, the resistance is 650N and the car moving at 50km/h the resistance is 960N.
(a). find an expression for R interms of V
(a) the resistance at 80km/h​

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.

Amass weighing 24 pounds, attached to the end of a spring, stretches it 4 inches. initially, the mass is released from rest from a point 8 inches below the equilibrium position. find the equation of motion. (use g = 32 ft/s2 for the acceleration due to gravity.)

If a star is moving toward earth, it is
