Answer:
The oldest functioning car is La Marquise, a steam-powered, four-wheeled, four-seater vehicle, manufactured by De Dion Bouton et Trépardoux (France) in 1884; three years later it won the world's first automobile race, powering along the 30.5-km (19-mile) track at an average of 42 km/h (26 mph) from Paris to Neuilly, .
Answer:
The displacement of the air drop after 3 second is 18.27 m.
Explanation:
Mass of the rain drop = m =
Weight of the rain drop = W
Duration of time = t = 3 seconds
Drag force on rain drop =
Motion of the rain drop:
Net force on the rain drop , F= W - D
v = 12.18 m/s
Initial velocity of the rain drop = u = 0 (since, it is starting from rest)
v=u+at (First equation of motion)
(second equation of motion)
s = 18.27 m
The displacement of the air drop after 3 second is 18.27 m.
The earth rotates (spins) at the same time as it orbits in a circular motion around the sun. fun fact : it takes 365 days to complete 1 orbit for 3 years and then 366 days for a leap year! you don't have to put that last part but maybe for some extra points you can!
