What are the energy requirements for digital signals?

What is the average speed of a car that travels 40 mph for 1 hour and 60 mph in another hour?

Two horses begin at rest. after a few seconds, horse a is traveling with a velocity of 10 m/s west, while horse b is traveling with a velocity of 13 m/s west. which horse had a greater acceleration? a. horse a because its change in velocity was greater than horse b's in the same time. b. horse b because its change in velocity was greater than horse a's in the same time. c. horse b because its change in velocity was the same as horse a's, but it took less time. d. both horses had the same acceleration.

If we compare the force of gravity to strong nuclear force, we could conclude that
