Answer:
a) v = 2.9 m / s, b) A = 0.350 m, c) v = 2.9 m / s, d) A = 1.00 m
Explanation:
The oscillatory motion is described by the expression
x = A cos (wt + Ф)
the wavelength which is the distance for the wave to repeat and the frequency which is the number of times a wave oscillates per unit of time
a) In this part they ask us for the speed of the wave.
Let's use the relationship between speed, wavelength and frequency
v = λ f
For the wavelength they indicate that the distance between two crest is 6.1 m
λ / 2 = 6.10
λ = 12.20 m
They give us the period of the wave is the time it takes to return to the same point, in this case they give half a period
A / 2 = 2.10
A = 4.20 me
f = 1 / t
f = ¼, 2
f = 0.238 Hz
let's calculate
v = 12.20 0.238
v = 2.9 m / s
b) the amplitude of the wave, is the distance from zero to some maximum
2A = 0.700
A = 0.350 m
c) the speed of the wave is not function of the amplitude, so the speed is the same
v = 2.9 m / s
d) the amplitude is
2A = 0.50
A = 1.00 m
Density = 7.36 grams ÷ (2 cm × 2 cm × 2cm) = 0.92 g/cm^3
Support and protect the body is NOT a function of the digestive system
Your body's skeletal structure serves as a support system. It gives the body its structure, permits mobility, produces blood cells, offers organs protection, and stores minerals. A different name for the skeletal system is the musculoskeletal system.
<h3>What is digestive system ?</h3>
The digestive system consists of organs that are crucial for breaking down both food and water. These include the anus, pharynx (throat), stomach, small and large intestines, rectum, and oesophagus.
- The body needs nutrients for energy, growth, and cell repair, and nutrients are broken down into via the digestive process. Prior to the blood absorbing nutrients from food and drink and transporting them to body cells, those nutrients must be broken down into smaller molecules.

Answer:
The momentum of the two-block system is 18 kg-m/s
Explanation:
It is given that,
Mass of block A,
Mass of block B,
Velocity of block A,
Velocity of block B, (it is moving in opposite direction)
We need to find the momentum of two block system. It is given by the product of mass and velocity for both blocks i.e.
p = -18 kg-m/s
So, the momentum of two block system is 18 kg-m/s. Hence, this is the required solution.
