Answer:
a) 5 m from the finish line
b) 4875 s
Explanation:
distance = 1 km
tortoise speed = 0.2 m/s
speed of hare = 8 m/s
time take by hare t reach 0.8 km =
time taken by tortoise to travel 1 km =
time taken by the hare to travel 0.2 km =
time taken by the tortoise to travel 0.2 km =
distance traveled by tortoise in 25 second = 25 × 0.2 = 5 m
a) when tortoise is 5 m from the finish line then hare will resume the race.
b) the hare will be stationary for = 5000 - 125 = 4875 s
Blue because usually people will think the color of water is blue so it will match/blend more than red or green
V= frequency x wavelength
The average velocity of a microwave is 3x10^8m/s.
3x10^8m/s= (.05m) x frequency
f= 6x10^9Hz
