Answer:
11.47answer
Explanation:
Height of the tower, s = 500 m
Velocity of sound, v = 340 m sˆ’1
Acceleration due to gravity, g = 10 m sˆ’2
Initial velocity of the stone, u = 0 (since the stone is initially at rest)
Time taken by the stone to fall to the base of the tower, t1
According to the second equation of motion:
S = ut1 + 1/2gt12
500 = 0 x t1 + 1/2 x 10 x t12
t12 = 100
t1 = 10s
Now, time taken by the sound to reach the top from the base of the tower, t2= 500/340 = 1.47 s
Therefore, the splash is heard at the top after time, t
Where, t= t1 + t2 = 10 + 1.47 = 11.47 s.
False
The ingredients of the salad determine how healthy it is.
Answer:
Because of its unique physical features
Explanation:
Nepal is rich in biodiversity because of its unique physical features, thus we find many types of flora and fauna here.
