A parent or other trusted adult, such as a school counselor, could give great problem solving advice.
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.
That is false. No one starts doing drugs with the conscious decision to become an addict.
Answer:
r = -6/5
Explanation:
1/2r + 6 = 3-2r
Firsly, get all the number without x to one side and number with x to the other side, we got:
Simplify 1/2r to be r/2,
r/2 + 6 =3 - 2r
Multiply both sides by 2:
r + 12 = 6 - 4r
r + 4r = 6 - 12
5r = -6
Divide both side by 5,
r = -6/5
Hope this help you :3
