Answer:
1.884 meters per second
Explanation:
s = d/t
d = C = 2πr = 2π(6) = 37.68 m
t = 20 s
s = (37.68 m)/(20 s)
s = 1.884 m/s
Answer: 1500metres
Explanation: the formula for distance is speed × time which equals 150m/min × 10 min = 1500m
This formula can be rearranged...
Speed = Distance ÷ time.
Time= Distance ÷ speed.
Distance= Time × speed.
The air around you has weight, and it presses against everything it touches. That pressure is called atmospheric pressure, or air pressure
Answer:
wave front
Explanation:
wave front is an imaginary line of a wave that joins all adjacent points that are in phase,
