Answer:
1: D- attach the muscle to bones and allow for movement
2:A- skeletal
3. A- speaking
Explanation:
25 km/h means that 15 kilometers will be 15/25ths of an hour. Therefore, 3/5 of an hour is 36 minutes, so it would take 36 minutes to fly that distance.
89.67J
Explanation:
Given parameters:
Mass of rock = 6.1kg
Height of fall = 1.5m
Unknown:
Potential energy = ?
Solution:
The potential energy is the energy at rest or due to the position of a body.
Potential energy is mathematically expressed as;
Potential energy = mgh
m is the mass of the rock
g is the acceleration due to gravity of the rock
h is the height of the rock
Potential energy = 6.1 x 9.8 x 1.5 = 89.67J

The acceleration of the given wave is 2.5m/s^2
<h3>Wave property</h3>
The standard wave function is expressed according to the equation
y = Asin(2πft+2πx/λ)
where
λ is the wave length
Given the equation below
y = 0.120 sin((π/8)x + 4πt)
Compare both equation to have:
(π/8)x = 2πx/λ
8 = 2/λ
λ = 2/8
λ = 1/4
λ = 0.25m
For the frequency
Compare both equation to have:
4πt = 2πft
4 = 2f
4/2 = 2f/2
f = 2 Hz
Speed = fλ
speed = 2(0.25)
speed = 0.5m/s
Determine the acceleration
acceleration = change in velocity/time
acceleration = 0.5/ 0.200
acceleration = 2.5m/s^2
Hence the acceleration of the given wave is2.5m/s^2
