7. A some s dropped from the top of a tower 500 m high into a pond of water at
the base of the tower. When is the splash heard at the top ?
= 10 ms and speed of sound = 340 ms?)
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.

The mechanical advantage of a wheel and axle is the radius of the wheel divided by the radius of the axle. On wheel and axle A, the wheel and axle are very close in size. On wheel and axle B, the radius of the wheel is much greater than the radius of the axle.
Answer:
The wheel and axle B has a greater mechanical advantage than wheel and axle B
Explanation:
Given
Let
[tex]R_W = Radius\ of\ the\ wheel[/tex]
[tex]R_A = Radius\ of\ the\ axle[/tex]
[tex]MA = \frac{R_w}{R_A}[/tex]
Required
Which wheel and axle has the greater mechanical advantage? (Missing Information)
For Wheel and Axle A:
[tex]R_w[/tex] is close to [tex]R_A[/tex]
For calculation purpose, we can assume that:
[tex]R_W \approx\ R_A[/tex]
So:
[tex]MA = \frac{R_w}{R_A}[/tex]
[tex]MA = \frac{R_A}{R_A}[/tex] or [tex]MA = \frac{R_W}{R_W}[/tex]
[tex]MA = 1[/tex]
For Wheel and Axle B:
[tex]R_w[/tex] far from [tex]R_A[/tex]
For calculation purpose, we can assume that:
[tex]R_W > R_A[/tex]
and
[tex]R_A = nR_A[/tex]
Where:
[tex]n > 1[/tex]
So:
[tex]MA = \frac{R_w}{R_A}[/tex]
[tex]MA = \frac{nR_A}{R_A}[/tex]
[tex]MA = n\frac{R_A}{R_A}[/tex]
[tex]MA = n * 1[/tex]
[tex]MA = n[/tex]
Since: [tex]n > 1[/tex]
Then
[tex]MA > 1[/tex]
So, we have:
[tex]MA = 1[/tex] ---> For Wheel and Axle A
[tex]MA > 1[/tex] ---> For Wheel and Axle B
By comparison, the wheel and axle B has a greater mechanical advantage than wheel and axle B

The knee is the complex and the largest joint of the human body and it helps in connecting the femur to the tibia bone in the leg region. Other smaller bones together make up the knee joint.
It is true that when the knees are out the pulling will be from the bigger muscles.
What is the role of the muscles in the knee?Muscles are important for the movement of the knee and its joint for locomotion and other activities. There are various muscles attached to the knee bones that help in knee movement.The muscles like the quadriceps, popliteus and hamstring allow knee movement, stability and balance of the bones. The knee muscles move in a stabilized manner for flexing, extending and stabilizing the knee movement.Thus, the statement is true.
