Under water turbans that are placed at the above to middle of the ocean they are used to capture kinetic motion
Answer:
a) red wave hs a longer wavelength than the green wave
b)f = 1.875 10¹¹ Hz
, f_green = 5.45 10¹⁴Hz
c) E = 1.24 10⁻²² J
, E_green = 3.6 10⁻¹⁹ J
d) The red wave is in the infrared range, heat waves
The green wave is in the visible wavelength
Explanation:
a) The green wave are on the left in the electromagnetic spectrum so the red wave has a longer wavelength than the green wave
The green wavelength is in the range of 550 10⁻⁹ m
The speed of the wave is
c = λ f
f = c /λ
b) The frequency of the red wave is
f = 3 10⁸ / 1.6 10⁻³
f = 1.875 10¹¹ Hz
For the green wave
f_green = 3 10⁸/550 10⁻⁹
f_green = 5.45 10¹⁴Hz
c) The photon energy is given by the Planck equation
E = h f
E = 6.63 10⁻³⁴ 1.875 10¹¹
E = 1.24 10⁻²² J
For the green wave
E_green = 6.63 10⁻³⁴ 5.45 10¹⁴
E_green = 3.6 10⁻¹⁹ J
d) The speed of electromagnetic waves is constant and has a value of 3 108 m / s
e)
The red wave is in the infrared range, heat waves
The green wave is in the visible wavelength

Answer:
The y-axis should be labelled as W in Newtons (kg·m/s²)
Explanation:
The given data is presented here as follows;
Mass (kg)
Newtons (kg·m/s²)
3.2
31.381
4.6
45.1111
6.1
59.821
7.4
72.569
9
89.241
10.4
101.989
10.9
106.892
From the table, it can be seen that there is a nearly linear relationship between the amount of Newtons and the mass, as the slope of the data has a relatively constant slope
Therefore, the data can be said to be a function of Weight in Newtons to the mass in kilograms such that the weight depends on the mass as follows;
W(m) in Newtons = Mass, m in kg × g
Where;
g is the constant of proportionality
Therefore, the y-axis component which is the dependent variable is the function, W(m) = Weight of the body while the x-axis component which is the independent variable is the mass. m
The graph of the data is created with Microsoft Excel give the slope which is the constant of proportionality, g = 9.8379, which is the acceleration due to gravity g ≈ 9.8 m/s²
We therefore label the y-axis as W in Newtons (kg·m/s²)
